What’s the Difference Between FHO and THR?

Femoral Head Ostectomy (FHO) and Total Hip Replacement (THR) are two surgeries used to treat severe hip problems in dogs, but they work in very different ways.

FHO involves removing the femoral head, the ball part of the hip joint. After removal, the body forms a fibrous false joint made of soft tissue. This structure cushions the joint and allows pain-free movement, though some function may be reduced.

In contrast, THR replaces both the femoral head and the socket with artificial implants, creating a new, smooth joint surface. This restores full joint structure and offers more natural motion, especially in large or active dogs.

FHO is simpler and less expensive but may not offer the same range of motion. THR gives better joint function but is more complex and costly, requiring careful case selection and recovery.

Which Dogs Are Best Suited for Each Surgery?

Femoral Head Ostectomy (FHO) and Total Hip Replacement (THR) are selected based on a dog’s size, age, and activity level.

FHO is generally better for small to medium-sized dogs, usually under 20–25 kg (45–55 lbs). These dogs often adapt well to the false joint formed after surgery. FHO is also used in cases where cost is a concern or when other health issues make THR too risky.

THR is ideal for larger dogs or highly active breeds, especially those who need full joint function for work, running, or athletic play. It offers more natural movement and strength.

Age is another factor. THR requires skeletal maturity, usually around 10–12 months old, to ensure stable implant placement. FHO can be performed at younger ages in some cases.

Lifestyle also plays a role. FHO suits lower-energy dogs or those with mild muscle loss. THR is better for dogs expected to return to high activity. Your vet will assess your dog’s build, age, and daily function to guide the best surgical choice.

Comparing Surgery Risks and Complexity

FHO and THR differ in complexity and risk, and choosing the right one involves understanding what each surgery requires.

• FHO is considered a less invasive and technically simpler procedure. It involves removing the femoral head without entering the joint capsule deeply. Complications are rare, and recovery is usually straightforward in smaller dogs.
• THR, on the other hand, is a more advanced surgery. It requires specialized implants, precise bone cuts, and careful placement of both the socket and ball components. This surgery takes longer, needs a highly trained surgeon, and carries greater risks—especially related to anesthesia, infection, and implant complications.

Despite these risks, THR is often preferred when joint function must be fully restored, such as in large breeds with severe arthritis or dysplasia. FHO may be favored for dogs with medical concerns, budget limits, or when joint damage is not extensive.

Your vet or surgeon will weigh these factors—including recovery potential and long-term goals—before recommending the most suitable approach.

Cost Comparison: FHO vs. THR

The cost of FHO and THR can vary based on your location, the veterinary surgeon’s expertise, and your dog’s specific case.

• FHO surgery typically costs $1,000 to $2,500. This often includes pre-op bloodwork, surgery, pain meds, and follow-up care.
• THR is more expensive, ranging from $4,000 to $8,000 per hip, depending on implant type and facility. It also covers X-rays, advanced anesthesia, implant materials, surgical fees, and longer post-op monitoring.

FHO has a lower upfront cost and fewer material needs, making it more accessible for many dog owners. However, THR may offer better long-term function, especially in large or active dogs—possibly reducing future rehab costs or mobility issues.

It’s important to consider both short-term affordability and long-term quality of life. While THR is more expensive, the improved comfort and mobility may justify the higher cost in many cases. Your vet will help break down what's included in the estimate so you can make an informed decision.

Recovery Time and Rehabilitation Needs

Both FHO and THR require careful recovery, but the timelines and expectations differ.

• FHO recovery is typically shorter. Dogs often begin weight-bearing within a few days to 1 week, and most regain good walking ability by 4–6 weeks. Physical therapy is key to rebuilding strength and balance. Exercises start slowly and progress over 6–12 weeks.
• THR recovery takes longer and is more structured. Dogs are usually confined to limited movement for 6–8 weeks, with leash walks and controlled rehab. Physical therapy focuses on restoring range of motion, balance, and joint use. Full recovery can take 12–16 weeks or longer.

In both cases, post-op care includes pain control, anti-inflammatory meds, suture removal, and vet follow-ups. Jumping, running, and rough play are restricted during early healing.

THR requires more frequent rechecks to monitor implant placement. FHO patients benefit from consistent at-home exercises and hydrotherapy. While both procedures lead to good outcomes, success depends heavily on owner compliance with rehab and post-op instructions.

Long-Term Outcomes: What to Expect

Both FHO and THR offer good long-term results, but they differ in joint function and comfort over time.

• FHO creates a fibrous false joint. Dogs typically regain strong mobility and pain relief, though a slight limp or reduced range of motion may persist. Most small to medium-sized dogs do very well, especially with early physical therapy. Muscle tone often returns gradually, though some asymmetry may remain.
• THR offers the most natural joint function, especially in larger breeds. Dogs usually regain a smooth gait, full leg use, and a higher level of physical activity. Once fully healed, many dogs return to running, swimming, and even agility work with no visible lameness.

Both procedures dramatically improve quality of life for dogs suffering from hip pain. Reported satisfaction is high among owners for both surgeries when post-op care is followed closely.

Overall, THR provides superior function but requires more investment. FHO is a reliable alternative with fewer resources needed—especially for dogs not demanding peak performance.

Potential Complications to Watch For

Each surgery has its own set of possible complications, though most dogs recover well when care is properly managed.

FHO complications may include:

• Persistent or returning pain
• Limb shortening causing mild gait changes
• Weakness or instability in the operated leg
• Delayed or incomplete muscle regrowth

These are more likely in large dogs or those who skip rehab.

THR complications can be more serious, including:

• Implant dislocation if the joint isn’t protected during healing
• Infection, which may require implant removal
• Loosening or wear of the implant over time
• Nerve injury during the procedure (rare)

Strict post-op restrictions help avoid most issues. THR requires more frequent checkups to monitor implant stability, especially in active dogs.

In both surgeries, careful follow-up, pain management, and rehab are key to preventing problems. If signs like swelling, limping, or reluctance to use the leg return, prompt veterinary attention is needed.

Making the Right Choice for Your Dog

Choosing between FHO and THR depends on your dog’s size, lifestyle, pain level, and your resources. Here’s a simple way to look at it:

• FHO is practical for small to medium-sized dogs, dogs with lower activity needs, or owners seeking a more affordable and lower-risk solution. It offers good pain relief and function, especially with early rehab.
• THR is ideal for larger, active dogs or those needing more complete joint restoration. It provides a smooth, stable joint and excellent mobility but requires more aftercare and cost.

Questions to discuss with your vet:

• Is my dog a candidate for THR based on size and health?
• How severe is the hip damage, and can FHO provide enough relief?
• What post-op care and rehab will be required in each case?
• Are there any risks based on my dog’s age or condition?

A thoughtful discussion with your veterinary surgeon ensures the best outcome for your dog’s comfort and mobility.

FAQs

Is FHO or THR better for large dogs?

Total Hip Replacement (THR) is generally the better option for large dogs. It restores full joint function, offers better limb alignment, and reduces long-term joint stress. While some large dogs do well with FHO, they may have ongoing weakness or limping due to the false joint. THR provides more stable, pain-free movement and is often recommended when size and activity demands are high.

Can my dog walk normally after FHO?

Yes, many dogs walk normally after Femoral Head Ostectomy (FHO), especially smaller breeds. While some dogs may have a slight limp or reduced range of motion, most regain strong walking ability and are pain-free. With proper rehab, muscle strength improves and compensates for the missing joint, allowing dogs to walk, run, and play comfortably in daily life.

How long does it take to recover from THR?

Recovery from Total Hip Replacement typically takes 12 to 16 weeks. Dogs are kept on restricted activity for the first 6–8 weeks, followed by gradual rehab. Physical therapy, controlled leash walks, and regular vet checks help ensure proper healing. Most dogs return to full activity and comfort by 4 months, though some may need longer based on age or fitness.

Is FHO painful for dogs long-term?

FHO usually provides long-lasting pain relief, especially when performed early and followed by rehab. Some dogs may experience minor discomfort or muscle imbalance long-term, especially large breeds. However, most dogs don’t show signs of pain and adjust well to the false joint. Consistent exercise, healthy weight, and muscle support help maintain comfort over time.

What happens if I can’t afford THR?

If THR is not affordable, FHO is a reliable alternative—especially for small or medium dogs. It’s less expensive and still offers pain relief and good mobility when combined with rehab. In some cases, conservative management (like weight control, joint supplements, and physical therapy) may help delay surgery. Your vet can guide you on the best budget-friendly plan for your dog’s needs.

Can a failed FHO be corrected with THR later?

Yes, Total Hip Replacement can be performed after a failed FHO, though the surgery is more complex. Scar tissue, bone changes, or muscle atrophy from the earlier procedure may affect implant placement. Still, experienced surgeons can often restore function and comfort with THR. If FHO doesn’t relieve pain or causes long-term issues, THR may be a viable second option.

‍

What Is a Luxating Patella in Dogs?

A luxating patella means the dog’s kneecap (patella) slips out of its normal groove in the thigh bone. Instead of gliding smoothly when the knee bends, the patella pops to the side. This causes pain, limping, or skipping during movement.

Medial patellar luxation (MPL) is the most common type, where the kneecap shifts inward toward the other leg. It’s more frequent than lateral luxation, which moves outward and is usually seen in larger breeds.

In bilateral MPL, both knees are affected. Dogs may show lameness in both hind limbs, bunny-hopping, or trouble rising and walking. Symptoms can appear on one side first but usually involve both knees over time. Bilateral cases can range from mild to severe and may require surgery to correct pain, improve limb use, and prevent long-term joint damage.

Why Do Some Dogs Get MPL in Both Knees?

Bilateral medial patellar luxation (MPL) often develops due to genetic and anatomical reasons. Some dogs are born with shallow grooves in their femur bones, which don’t hold the kneecap in place well. Over time, this leads to luxation—often in both legs.

Small breeds are more prone to bilateral MPL. Dogs like Pomeranians, Yorkshire Terriers, Chihuahuas, and Toy Poodles are commonly affected. These breeds tend to have inherited bone structures that don’t properly support the patella during movement.

Another major factor is limb alignment. If a dog’s legs are naturally bowed or rotated, it puts abnormal pressure on both knees. This uneven force allows the patella to move out of place in both limbs. Bone deformities in the femur or tibia, or tight soft tissues, also contribute.

Because these traits are often present in both hind limbs, it’s not unusual for both knees to develop MPL. In many cases, one side starts showing symptoms first, but the second knee usually follows. Early diagnosis helps prevent worsening on both sides.

Signs of Bilateral MPL You Should Watch For

When both knees are affected by MPL, the symptoms are often more noticeable and can affect your dog’s daily life. One of the most common signs is a skipping gait—your dog may hop with both back legs off the ground, especially during fast movement. This happens when both kneecaps slip out of place.

Other warning signs include:

• Limping or stiffness in both hind legs
• Bunny-hopping while walking or running
• Difficulty getting up from rest or lying down
• Reluctance to climb stairs or jump onto furniture
• Occasional yelps when moving awkwardly

Some dogs may try to avoid using their hind legs altogether or shift more weight to their front limbs. This can lead to muscle loss in the back legs and an arched posture over time.

Because bilateral MPL affects both knees, these signs can be harder to spot than a limp on one side. Owners might think their dog is just lazy or tired, especially in small breeds that don’t show pain clearly. But early signs like bunny-hopping or hesitation with movement usually indicate both knees are involved. Timely vet evaluation can confirm the condition and guide treatment before it worsens.

How Vets Grade Bilateral MPL

Veterinarians use a grading system from 1 to 4 to assess the severity of patellar luxation in each knee. In bilateral MPL, both knees are evaluated separately, but treatment planning considers the overall effect on the dog.

• Grade 1: The kneecap moves out of place with pressure but returns on its own. Dogs often show no signs.
• Grade 2: The patella slips out more easily and may stay luxated briefly. Dogs may limp or skip occasionally.
• Grade 3: The kneecap is out most of the time but can be pushed back manually. Dogs often have persistent limping.
• Grade 4: The patella is permanently luxated and cannot be moved back. This causes severe lameness and structural changes.

Each grade reflects how unstable the joint is. Dogs with different grades on each leg may use one leg more than the other, but bilateral issues still impact both limbs over time. Grading helps determine whether surgery is needed and which leg to operate on first. It also guides rehab and long-term care planning.

How Bilateral MPL Is Diagnosed

Diagnosing bilateral medial patellar luxation (MPL) begins with a detailed physical exam. During the exam, the vet palpates both knees to feel how easily the kneecaps move out of place. The dog may be gently walked or trotted so the vet can observe signs like limping, skipping, or uneven gait.

Radiographs (X-rays) are commonly used to confirm the diagnosis. They show the alignment of the kneecap, femur, and tibia. In more complex or severe cases, especially with suspected bone deformities, CT scans may be recommended for a more detailed view of joint anatomy. Both knees are evaluated, even if symptoms appear worse on one side.

Early and accurate detection is key to successful treatment. Identifying the grade of luxation in each knee helps guide the right plan—whether that means monitoring, conservative care, or surgery. Since bilateral MPL can worsen over time, even mild cases should be regularly checked. Timely diagnosis helps prevent pain, joint damage, and complications in both knees, especially in young or small-breed dogs.

Treatment Options: Conservative vs Surgical

Not all cases of bilateral MPL require surgery. Mild or early-stage luxation (Grade 1 or 2) can often be managed conservatively—especially if the dog is not in pain and stays active.

Conservative treatment includes:

• Weight management: Reducing excess weight lowers stress on the joints
• Joint supplements: Products containing glucosamine and chondroitin may support cartilage health
• Controlled activity: Limiting jumping and fast running helps avoid injury
• Physical therapy: Light exercises can help build muscle and support knee stability

This approach works best for smaller dogs with low-grade luxation who aren’t showing consistent lameness. However, if symptoms worsen or if the patella dislocates frequently, surgery becomes necessary.

Vets typically recommend surgery for Grade 3 and 4 luxations or if both knees are causing discomfort and mobility issues. The decision depends on the dog’s quality of life, level of pain, and risk of long-term joint damage if left untreated.

Surgical Options for Bilateral MPL

When surgery is needed for bilateral MPL, the goal is to restore normal patella alignment and joint function. Surgeons may use one or more of these procedures:

• Trochleoplasty: Deepening the groove in the femur to hold the patella in place
• Tibial tuberosity transposition (TTT): Repositioning the bony attachment of the patellar tendon
• Soft tissue balancing: Tightening or releasing tissues to improve kneecap tracking

Some dogs may also need bone reshaping or correction if limb deformities contribute to the luxation. Each knee is assessed individually, and the surgical plan is tailored to the severity on each side.

For bilateral cases, vets may stage the surgeries—correcting one knee first, then the second after initial recovery. This reduces stress during rehab and allows the dog to use one stable leg. In select cases, both knees may be operated on at once, but only if the dog’s health and recovery environment are well controlled. The decision depends on age, weight, support at home, and overall health.

What to Expect After Bilateral Surgery

Recovery from bilateral MPL surgery requires patience and planning. Whether surgeries are done together or separately, dogs need strict rest and restricted movement for the first 4 to 6 weeks. Crate rest, short leash walks, and avoiding stairs or furniture are essential.

• Timeline: Weight-bearing usually starts within 1–2 weeks. Stronger walking returns by 4–6 weeks, and full recovery may take 3–4 months per leg.
• Post-op care: Pain medication, anti-inflammatories, and ice therapy help in the early days.
• Physical therapy: Gentle exercises and hydrotherapy build strength, restore motion, and prevent stiffness.

Follow-up visits are important to monitor progress, remove sutures, and assess healing through exams or X-rays. If only one leg is repaired first, the second surgery is often scheduled 6–8 weeks later, depending on the dog’s progress. Owners should be prepared for close monitoring and regular vet guidance during recovery.

Long-Term Outlook for Dogs With Bilateral MPL

With proper treatment, most dogs with bilateral MPL do very well long-term. The prognosis depends on the grade of luxation and treatment method. Dogs with mild cases managed conservatively can live comfortably with lifestyle changes and monitoring.

For those who undergo surgery:

• Over 90% return to normal or near-normal activity, especially small to medium-sized breeds
• Many regain the ability to walk, run, and play without pain
• Regular rehab and weight control support long-term success

However, untreated or poorly managed bilateral MPL can lead to complications. Chronic luxation causes cartilage wear, arthritis, and even rupture of the cranial cruciate ligament (CCL). These issues make future treatment more complex and reduce quality of life.

Timely surgery, rehab, and follow-up care give the best outcomes. With the right plan, most dogs can enjoy a happy, active life—even after dealing with MPL in both knees.

FAQs

Is it common for dogs to have MPL in both legs?

Yes, it’s fairly common for dogs—especially small breeds—to develop medial patellar luxation (MPL) in both knees. Genetic factors and limb alignment often affect both legs equally. Even if signs appear on one side first, the second knee may develop symptoms later. Bilateral cases are more likely in breeds like Pomeranians, Yorkies, and Toy Poodles.

Can my dog walk normally after bilateral MPL surgery?

Most dogs regain normal or near-normal walking after bilateral MPL surgery, especially with good post-op care and physical therapy. Some dogs may have a mild limp during recovery, but this usually improves with time. Once healing is complete, many dogs return to regular activity, including running and playing, without ongoing pain.

How long is recovery if both knees are treated?

If both knees are treated (either together or one at a time), full recovery can take 4 to 6 months. Initial weight-bearing starts within 1–2 weeks. Dogs typically walk better by 4–6 weeks per leg. Physical therapy and vet follow-ups help track healing and speed up muscle strength return.

Should both knees be operated at the same time?

In some cases, yes—both knees can be operated on at the same time, especially in smaller, lighter dogs with strong home care support. However, most vets prefer staging the surgeries, treating one knee first and the other after recovery. This reduces stress and makes rehab easier for the dog and caregiver.

Is surgery always needed for bilateral MPL?

No, not always. Mild cases (Grade 1 or 2) in both knees may be managed with weight control, supplements, and activity changes. But if your dog shows frequent limping, pain, or reduced mobility, surgery becomes necessary. Your vet will grade both knees and recommend the best course based on your dog’s comfort and function.

What happens if I don’t treat MPL in both knees?

Untreated bilateral MPL can lead to chronic pain, joint damage, and arthritis. Over time, the abnormal movement wears down cartilage, affects muscle balance, and increases the risk of ligament injuries like cruciate tears. Delaying treatment can make surgery more complex and limit long-term success. Early intervention offers the best outcome.

‍

Does FHO Surgery Improve a Dog’s Long-Term Quality of Life?

• Pain reduction over time
  Most dogs experience steady pain relief as healing progresses. The removal of the femoral head eliminates bone-on-bone contact, which greatly reduces chronic discomfort.
• Overall comfort in daily activities
  Dogs typically return to normal or near-normal activity levels after recovery. They walk, run, and play comfortably, especially when rehab exercises are followed properly.
• Owner satisfaction reports
  Studies show that 83–96% of dog owners report positive long-term outcomes after FHO surgery. This includes restored mobility, better temperament, and improved energy levels.

Over time, dogs regain function in the affected limb and adapt well to the “false joint.” While minor gait changes can remain, they usually don’t affect the dog’s comfort or activity. With proper care, most dogs enjoy a pain-free life and stay active for years after FHO.

How Well Do Dogs Walk After FHO Surgery?

Most dogs walk well after FHO surgery, especially once the healing process is complete.

• Gait returns to near-normal: Within a few weeks, many dogs start walking and even trotting with minimal signs of discomfort.
• Mild limps or bunny-hopping may appear: Some dogs develop minor adaptations like a mechanical limp or occasional bunny-hopping, especially during fast movement. These don’t usually affect daily function.
• Recovery timeline: Most dogs begin bearing weight in 1–2 weeks. Comfortable walking is often seen by 4–6 weeks, with near-full recovery taking 3–6 months.

Smaller breeds often recover faster and with fewer visible changes. For larger dogs, it might take more time and support. Still, pain reduction is quick, and quality of life improves significantly after surgery. Owners often report their dogs appear more active and willing to move shortly after the initial recovery period.

What Physical Changes Might Persist After Surgery?

After FHO, some physical changes can remain long-term, even with good recovery.

• Muscle atrophy: The thigh and hip muscles may shrink due to pre-surgical limping or disuse. While rehab helps, full muscle mass may not return.
• Leg shortening: Removing the femoral head can cause the surgical limb to appear slightly shorter. This usually doesn’t affect mobility.
• Decreased range of motion: Without a true joint, hip flexibility may be reduced. Dogs compensate well, but some stiffness might stay.
• Weight-bearing ability: While walking may look normal, some dogs shift more weight to the opposite leg when standing still.

These changes are often mild and don’t limit function. Most dogs adapt fully, especially if they’re active and supported with good rehab. Long-term comfort remains excellent despite these small structural differences.

What Kind of Joint Forms After FHO Surgery?

FHO creates a fibrous pseudo-joint in place of the natural hip joint.

Once the femoral head is removed, no bony connection remains between the femur and pelvis. Instead, the body forms a soft tissue capsule filled with fibrous tissue. This tissue cushions the joint, allowing smooth, pain-free movement.

Though not a real joint, the pseudo-joint acts as a shock absorber. It molds to the dog’s motion patterns over time. This adaptability supports walking, running, and even playful activity in most dogs.

The joint’s long-term durability is excellent, especially when weight is controlled and rehab is consistent. While large dogs might show slight instability or reduced motion, the fibrous joint holds up well in the long run.

What Factors Affect Long-Term Outcomes?

Several things impact how well a dog recovers after FHO:

• Dog’s size and body weight: Smaller dogs tend to recover better. Larger breeds may need longer rehab and may show more noticeable gait changes.
• Chronic vs acute hip issues: Dogs with long-standing arthritis or hip dysplasia may have more muscle loss before surgery, affecting results. Dogs with recent trauma often do better.
• Surgical alternatives: In some cases, especially in large or active dogs, total hip replacement (THR) may offer smoother motion and a more natural gait. Still, FHO remains a great option when cost or health limitations rule out THR.

In general, FHO provides excellent comfort and good function in most dogs. The key is matching the procedure to the dog’s size, health, and activity level.

Role of Rehab in Long-Term Success

Rehabilitation is one of the most important parts of FHO recovery.

• Start early: Light rehab usually begins within a few days post-surgery to maintain joint motion and avoid muscle loss.
• Hydrotherapy is very effective: Water-based exercises help build strength without stressing the joint.
• Rehab duration varies: Some dogs may need a few weeks, while older or larger dogs benefit from longer therapy plans.

Exercises like leash walks, sit-to-stand drills, and gentle hill work can be added as healing progresses. Rehab not only improves muscle strength but also teaches the dog to use the leg properly again. Follow-ups with your vet or a certified canine rehab specialist ensure the exercises are working. A strong rehab plan often makes the difference between average and excellent outcomes.

Final Thoughts: Is FHO a Reliable Long-Term Option?

FHO is a reliable and proven surgery, especially for:

• Small to medium-sized dogs
• Dogs with hip injuries, fractures, or chronic joint pain
• Cases where cost or health limits more advanced surgery like THR

While some changes in gait or muscle tone may remain, dogs usually regain full function. Most live pain-free, active lives with no ongoing medication or surgery needed. Larger dogs can still do well with FHO, but their success depends heavily on proper rehab and weight control.

Your vet will help determine if FHO is right for your dog. When combined with thoughtful aftercare and consistent support, it offers lasting relief and good quality of life for years to come.

FAQs

Can dogs live a normal life after FHO surgery?

Yes, most dogs live a very normal and active life after FHO surgery. Once healed, they can walk, run, and play comfortably. Some dogs may have a slight limp or reduced range of motion, but these issues rarely affect their quality of life. With good rehab and proper care, long-term pain relief and function are excellent, especially in small to medium-sized dogs.

How long does it take for a dog to fully recover from FHO?

Full recovery typically takes 3 to 6 months. Most dogs begin bearing weight within 1 to 2 weeks and walk comfortably by 4 to 6 weeks. Rehab speeds up the healing process and helps rebuild lost muscle. Even after reaching full function, some dogs may continue to improve in strength and coordination over time with continued activity and exercise.

Will my dog limp permanently after FHO?

Some dogs may have a mild limp that shows up when they’re tired or moving quickly, but it’s usually not permanent or painful. In many cases, the limp fades over time with rehab and strengthening. Even if a minor limp remains, most dogs don’t show signs of discomfort and can live a very active, happy life.

Is FHO surgery effective in large breeds long-term?

FHO can work in large dogs, but results vary more than in smaller breeds. Success depends on factors like body weight, muscle condition, and rehab effort. Large dogs may retain a noticeable gait change or reduced strength, but many still do well. For very active or working dogs, total hip replacement may offer better function in the long term.

What is a false joint, and does it last?

A false joint, or pseudo-joint, is a fibrous capsule that forms after the femoral head is removed. It’s not made of bone or cartilage but allows smooth, cushioned movement. This structure holds up well over time and provides lasting pain relief. While it doesn’t restore full range of motion, it typically allows good mobility for life.

Does physiotherapy really make a difference long-term?

Yes, physiotherapy has a major impact on long-term success. It helps restore muscle strength, improve joint motion, and teach your dog to use the leg properly again. Dogs who receive structured rehab often recover faster and show better function long-term. Skipping rehab can lead to stiffness, weakness, and less complete recovery.

Average Cost of MPL Surgery

• Common cost per knee: Most MPL surgeries range from $1,500 to $3,500 per knee in the U.S.
• Bilateral surgery (both knees): Costs can double, totaling $3,000 to $7,000, depending on complexity and clinic.
• Additional charges: Include diagnostics, post-op care, medications, and follow-up visits.

Many dog owners on forums like Reddit report paying between $2,000 and $2,800 for a single knee surgery at specialty clinics, while others paid over $5,000 for more complex bilateral cases. Prices often vary based on location, surgeon expertise, and whether orthopedic specialists are involved.

For example:

• In urban areas, surgery at a referral hospital may cost $3,500+ per knee.
• In smaller towns, general vet clinics may charge closer to $1,500–$2,000.

Always ask for a full estimate, including recovery costs. Total expenses can vary greatly, but the surgery is often worth it to restore mobility and reduce pain.

What Affects the Cost of MPL Surgery?

• Clinic location: Urban clinics often charge more due to higher operating costs.
• Surgeon type: Board-certified orthopedic surgeons usually charge more than general vets.
• Dog-specific factors: Size, weight, and breed can affect anesthesia and recovery needs.
• Luxation grade: Higher grades (III or IV) require more complex surgery.
• Unilateral vs. bilateral: Correcting both knees doubles the cost in most cases.

The cost of MPL surgery can vary widely depending on these factors. For example, a Grade I case in a small dog might only require a basic procedure done by a general vet, costing under $2,000. But a Grade IV case in a large breed with both knees affected may need a specialist, pushing costs beyond $6,000.

These variables highlight why vets provide a cost estimate only after physical exams and imaging. Tailoring treatment to the dog’s needs ensures the best care and cost accuracy.

Additional Expenses Beyond Surgery

• Rehabilitation therapy: Sessions like physiotherapy or hydrotherapy can add $50–$150 per session.
• Medications and supplements: Pain relievers, antibiotics, and joint support can cost $100–$300 post-op.
• Follow-ups and imaging: X-rays and exams may total another $200–$500 over several visits.

While the surgery itself is a major cost, owners should prepare for extra recovery-related expenses. Post-surgery rehab is especially important for Grade III–IV MPL cases and large breed dogs, helping them regain strength and avoid complications.

Some clinics bundle post-op care in the initial estimate, while others bill separately. Ask for a breakdown so you’re not caught off guard. Keeping up with follow-ups and wound care is key to your dog’s full recovery and successful long-term outcome.

Can Pet Insurance Help Cover the Cost?

• What’s covered: Most accident and illness plans include MPL surgery if the condition wasn’t pre-existing.
• Limits and waiting periods: Many policies exclude MPL if diagnosed or noted before the waiting period ends.
• Reimbursement tips: Choose a plan with orthopedic coverage, submit all vet records, and clarify exclusions early.

Pet insurance can be a big help in covering surgery costs, but it’s not guaranteed. If your dog had prior signs of lameness or joint issues, some insurers may deny MPL claims.

To maximize coverage, insure your dog while still young and healthy. Policies from providers like Trupanion or Healthy Paws often reimburse 70–90% of eligible costs after deductibles. This can ease the burden, especially if both knees require surgery.

Cost of MPL with Other Procedures

• TPLO + MPL correction: These dual procedures may cost $4,000 to $6,000 or more depending on the dog’s size.
• Bilateral TPLO with MPL: This complex combo can exceed $7,000–$10,000, especially in large breeds.

Some dogs need additional knee procedures alongside MPL correction. This is most common when a dog has both a luxating patella and a torn cruciate ligament, requiring TPLO (Tibial Plateau Leveling Osteotomy).

In such cases, vets may combine surgeries to reduce overall anesthesia time and recovery periods. This can save on costs in the long run but increases the upfront price. If both knees are affected, expenses rise further due to surgical time, implant hardware, and follow-up therapy.

Always ask your vet if bundled procedures are possible and what recovery support will be required.

Final Thoughts on Affording MPL Surgery

• Plan ahead: Start budgeting once symptoms begin or diagnosis is confirmed.
• Explore financing: CareCredit and vet-specific payment plans can ease the burden.
• Look into nonprofits: Some organizations offer grants or low-cost surgery for pet owners in need.

MPL surgery can be a big financial decision, but it often brings life-changing results for your dog. With good pain control, rehab, and vet support, many dogs return to an active, pain-free life.

Talk to your vet about all your options—from staged surgery to partial treatments. The key is addressing the condition early to avoid worsening pain and more costly interventions down the line.

FAQs

Is MPL surgery worth the cost for dogs?

Yes, for many dogs, MPL surgery greatly improves comfort, mobility, and long-term joint health. It prevents chronic pain, arthritis, and further injury like cruciate ligament tears. While the upfront cost may seem high, the benefits in quality of life and reduced future medical expenses often make it a worthwhile investment for your dog’s well-being.

Why do MPL surgery costs vary so much?

MPL surgery costs vary due to factors like the surgeon’s expertise, clinic location, and whether the surgery is for one or both knees. Dogs with higher-grade luxation or additional orthopedic problems may need more complex procedures, which cost more. Post-op care and imaging needs also influence the total cost, causing wide price ranges across clinics.

Can MPL be treated without surgery to save money?

Mild cases (Grade I or some Grade II) can sometimes be managed conservatively with weight control, joint supplements, and limited activity. However, this doesn’t fix the joint alignment. If symptoms worsen or quality of life declines, surgery becomes necessary. Non-surgical management may delay, but not always avoid, the need for future surgical correction.

What’s the cheapest way to get quality MPL surgery?

To save costs while ensuring quality, compare quotes from multiple clinics, including university vet hospitals or nonprofit organizations. Some general veterinarians with orthopedic experience may charge less than board-certified specialists. Also, ask about bundled pricing or payment plans. Just ensure the clinic follows modern surgical standards and post-op protocols.

Does MPL surgery cost more for larger dogs?

Yes, larger dogs often require more anesthesia, larger implants, and longer recovery support, which increase costs. Their surgeries may also be more complex due to weight-bearing pressure on the joints. That said, early treatment in large breeds can still prevent costlier issues like torn ligaments or advanced arthritis later in life.

Are there affordable rehab options after surgery?

Yes. While professional rehab centers offer hydrotherapy and guided exercises, many owners manage recovery with home-based rehab under veterinary guidance. Simple exercises like controlled leash walks, sit-to-stand drills, and gentle massage can be effective. Ask your vet for a customized plan, and consider occasional check-ins with a rehab specialist if needed.

What Is FHO Surgery and Why It's Done

Femoral Head Ostectomy (FHO) is a surgical procedure where the femoral head and neck are removed to relieve hip joint pain. It’s often used in small to medium-sized dogs when the hip joint is damaged by trauma, arthritis, or diseases like Legg-Calvé-Perthes.

• Why vets recommend FHO: It’s less invasive and more affordable than total hip replacement.
• Best for dogs under 50 lbs: These dogs form a functional “false joint” from scar tissue more easily.
• When it’s preferred: In cases where bone quality is poor, cost is a concern, or total hip replacement isn’t feasible.

After surgery, a fibrous tissue capsule forms in place of the removed joint. This “false joint” lets dogs walk without bone-on-bone contact. The success of FHO depends heavily on post-surgical care, including early movement, physical therapy, and weight management. When done in the right patient, this procedure helps restore pain-free movement and a good quality of life.

How Successful Is FHO Surgery in Dogs?

FHO surgery has a high success rate, especially in smaller dogs. Studies and owner feedback show strong outcomes.

• Owner satisfaction: Around 93–96% of pet owners report improved quality of life.
• Clinical outcomes: Most dogs regain near-normal mobility with minimal pain.
• Short-term recovery: Dogs may limp or have muscle loss early on but show clear improvement by 4–6 weeks.
• Long-term results: With rehab, most dogs can run, jump, and even hike.

Dogs who receive proper rehab therapy and have good muscle condition before surgery tend to do better. Vets see fewer complications and faster recovery in these dogs. The most important factor? Post-op care at home. With cage rest early on, followed by active physical therapy, most dogs regain strength and mobility. Even dogs with prior pain and stiffness often return to playful, active lives after full recovery.

Factors That Influence Success Rate

FHO outcomes depend on several key factors that dog owners and vets must consider.

• Dog’s size and weight: Small to medium dogs (<50 lbs) do best.
• Muscle strength: Pre-surgery conditioning helps with post-op recovery.
• Weight management: Obese dogs may recover slower and with more complications.
• Timely surgery: Delayed treatment can lead to more muscle loss.

Surgical skill and proper technique matter, too. But even with excellent surgery, poor aftercare can affect healing. That’s why owners must follow rehab plans closely. Dogs kept active before surgery tend to form stronger “false joints” and recover faster. Dogs with severe muscle wasting or untreated hip pain for long periods may struggle more with post-op mobility.

FHO is not a magic fix—it’s a team effort between vet and owner. With proper planning and care, though, the success rate is high, and the benefits are long-lasting.

Recovery Timeline and What to Expect

The healing process happens in stages and varies by dog, but most follow a general timeline.

• Day 1–3: Crate rest, pain meds, and short leash potty breaks only.
• Week 1–2: Passive range-of-motion exercises and short walks begin.
• Week 3–6: Walking improves; light exercises increase gradually.
• Week 6–12: Full muscle recovery and normal activity returns.

Dogs usually start weight-bearing within a week, though limping is common. Rehab exercises help rebuild muscle strength. Hydrotherapy, leash walking on inclines, and sit-to-stand drills are often used.

It’s important to monitor your dog’s pain levels and mobility each week. Swelling or lameness that worsens should be reported to your vet. By 3 months, many dogs resume near-normal movement, though some may retain a slight limp. Don’t rush the process. A slow, steady recovery gives the best long-term results.

Possible Long-Term Complications

While FHO is generally successful, there can be long-term issues in some dogs.

• Limb shortening: A minor leg length difference is common but usually not limiting.
• Gait changes: Some dogs have a permanent limp or altered stride.
• Reduced hip motion: Range of motion may not fully return in all cases.
• Muscle atrophy: Can occur if physical therapy is skipped or limited.

Most of these issues don’t impact quality of life significantly, but they can affect athletic performance in working or very active dogs. These risks are lower in smaller dogs and those who stick to rehab programs. Owners should stay in touch with their vet and schedule check-ups during the recovery period to detect any concerns early.

Bilateral FHO: What If Both Hips Are Affected?

Dogs with problems in both hips can still benefit from FHO—sometimes on both sides.

• One side at a time: Vets usually recommend staging surgeries.
• Quality of life: Most dogs return to normal walking after both hips heal.
• Research support: Studies show high success in bilateral cases.

Rehab is even more critical when both hips are involved. Dogs need help with balance and coordination during recovery. Use of slings or harnesses indoors and careful progress with leash walking helps prevent injury or overuse. With time and support, many dogs with bilateral FHO can run, play, and live happily pain-free.

When Is FHO the Best Option?

FHO is often chosen when other treatments aren’t suitable or accessible.

• Compared to total hip replacement: FHO is more affordable and less invasive.
• Best choice for: Smaller dogs, those with poor bone health, or those not suited for implants.
• When owners can’t afford implants: FHO is a reliable “salvage” procedure.

It’s not ideal for large-breed dogs or those needing high-performance mobility, like working dogs. However, for family pets with chronic hip pain and limited function, FHO can restore comfort and ease of movement. It’s especially helpful for younger dogs with trauma and seniors who can’t tolerate complex surgeries.

‍

FAQs

Is FHO surgery painful for dogs?

Yes, like any surgery, FHO can cause pain at first. However, your vet will prescribe pain medications to manage it during the early days. Most dogs show reduced discomfort within a few days. As healing progresses, pain decreases, and the dog often becomes more active. The long-term goal is to eliminate chronic hip pain caused by the original condition.

Can large breed dogs have a successful FHO?

Large dogs can have successful outcomes, but results are less predictable than in smaller dogs. They may retain a limp or limited range of motion. With strong muscles and proper rehab, some large dogs still regain good function. In general, total hip replacement is often preferred for larger breeds if it's financially and medically possible.

How long before my dog can walk after FHO?

Most dogs begin to bear weight within 3–7 days after surgery. At first, the walk may be wobbly or limping. With gentle rehab, walking improves each week. By 4–6 weeks, dogs typically walk more normally. Full recovery, including muscle rebuilding and pain relief, usually takes about 8–12 weeks.

What are signs the surgery didn’t work well?

Signs of poor recovery include persistent lameness, unwillingness to walk, pain when touching the hip, or muscle wasting over time. These may suggest complications like scar tissue problems or inadequate rehab. If you notice these, consult your vet immediately for re-evaluation and possible therapy adjustments.

Does FHO affect lifespan or activity levels?

FHO does not shorten your dog’s lifespan. With proper care, most dogs return to normal or near-normal activity levels. They can run, play, and live comfortably. Some may have a mild limp, but this usually doesn’t affect their happiness or quality of life. Long walks and active play are still possible after recovery.

Is physical therapy necessary after FHO?

Yes, physical therapy is very important for success. It helps rebuild muscle strength, improves range of motion, and speeds up recovery. Rehab exercises like leash walks, sit-to-stand drills, or hydrotherapy make a big difference. Without it, your dog may limp longer or never fully regain function. Always follow your vet’s rehab plan.

‍

What to Expect After FHO Surgery

Understanding what happens after Femoral Head Ostectomy (FHO) helps you prepare for each stage of your dog’s recovery.

• First 1–2 days: Your dog may feel drowsy due to anesthesia. Pain medication and strict rest are essential during this time.
• Week 1–2: You may notice some swelling or bruising near the surgical area. Your dog might begin light toe-touching or brief weight-bearing on the leg.
• Week 3–6: Controlled rehab begins. This includes slow leash walks and light physical therapy to rebuild muscle and range of motion.
• Week 7–12: Most dogs regain normal function by this stage. Some may still have minor stiffness or muscle loss that improves with ongoing activity.

The goal of post-op care is to support healing, reduce pain, and restore function. With your help, proper rest, gradual exercise, and vet check-ups, your dog can return to a comfortable, active life.

Immediate Post-Surgery Care (Days 1–3)

The first few days after FHO surgery are critical for setting the stage for healing. This period focuses on pain control, limiting movement, and protecting the surgical site.

• Crate rest and safe confinement: Keep your dog in a small, quiet space like a crate or pen. This helps avoid sudden movements that may stress the healing leg.
• Leashed potty breaks only: Take your dog outside on a leash for bathroom needs. Avoid stairs, running, or jumping.
• Using ice therapy: Apply a cold pack (wrapped in a towel) over the surgical site for 10–15 minutes, 2–3 times daily. This reduces swelling and discomfort.
• Starting passive range-of-motion exercises: Your vet may show you how to gently move the leg to keep the joint flexible. Do this only if approved.
• Preventing licking or chewing: Use an E-collar or recovery sleeve to protect the incision from infection.
• Giving prescribed meds: Administer all pain medications and antibiotics exactly as directed by your veterinarian.

This stage is all about keeping your dog comfortable, minimizing movement, and preventing complications. Follow your vet’s instructions closely to avoid setbacks and support a smooth recovery. Consistency in care here makes a big difference later.

Caring for the Incision Site

In the first two weeks after FHO surgery, taking care of the incision is crucial for preventing infection and promoting healing.

• How often to check the wound: Inspect the incision 1–2 times daily for redness, swelling, or discharge.
• Signs of infection to watch for: Look out for pus, foul smell, increased redness, or warmth around the incision. If your dog licks the area excessively or seems in pain, contact your vet.
• Keeping the incision clean and dry: Do not apply creams or sprays unless your vet advises. Avoid letting the incision get wet or dirty—this includes keeping your dog away from muddy areas or damp grass.
• Bathing restrictions and suture removal timing: Do not bathe your dog until the sutures are removed or the incision is fully healed—typically 10–14 days after surgery. Your vet will advise if staples or stitches need removal.

Keep your dog’s environment clean and calm. Prevent licking with an E-collar or soft recovery cone. With good wound care, you reduce the chance of infection and help your dog heal faster.

Early Rehab Tips (Days 4–14)

This phase introduces gentle movement to prevent stiffness and starts building comfort with basic activity.

• Warm compresses and massage: Apply a warm compress (not hot) for 10 minutes before massage. Gently massage muscles around the hip to improve blood flow and reduce tension.
• Gradual leash walking routine: Begin with 5-minute walks on flat surfaces 2–3 times a day. Use a short leash and walk slowly.
• Supporting with sling/harness indoors: For dogs with weak hind limbs, a rear-support sling or towel under the hips helps reduce strain.
• Encouraging calm behavior while healing: Limit excitement and prevent jumping or rough play. Use food puzzles and chews to keep your dog mentally stimulated while physically resting.

These small steps set the foundation for long-term healing. Always follow your vet’s rehab plan and observe how your dog responds to gentle movement.

Strength-Building and Exercise (Weeks 2–6)

As healing progresses, the focus shifts to rebuilding strength and range of motion in the hip and leg.

• Sit-to-stand drills and wall sits: Encourage your dog to sit and stand slowly, 5–10 times in a row. Use a wall to support the healthy side during “wall sits.”
• Walking up inclines and gentle ramps: Start with low slopes or shallow ramps to engage the hip joint without stress.
• Controlled leash walks: how to progress safely: Increase walk time by 5 minutes each week if no limping occurs. Avoid slippery or uneven surfaces.
• Hydrotherapy and swimming introduction: Swimming is a low-impact way to rebuild muscles. Use a life vest and only in vet-approved, clean water environments.
• Using ice after exercise: Apply ice for 10–15 minutes on the hip after exercise sessions to reduce inflammation.

This stage helps restore normal movement. Track progress daily and adjust activities if soreness or fatigue appears.

Monitoring Healing and When to Call the Vet

Ongoing monitoring helps catch issues early and ensures your dog stays on track with recovery.

• Follow-up exam timing: Most vets schedule a recheck around 2 weeks post-surgery, then again at 6–8 weeks.
• What is normal vs. warning signs: Mild swelling, slight limping, or low activity is common. Warning signs include severe limping, refusal to walk, or signs of pain when touched.
• Dealing with swelling, bruising, or seroma: Minor swelling or fluid buildup (seroma) is usually not serious. If the area gets warm or painful, call your vet.
• When rehab support is needed: If your dog struggles with exercises or limping worsens, seek help from a vet or certified canine rehab therapist.

Don’t ignore small changes—early action prevents long-term issues. Regular updates with your vet ensure recovery stays on track.

Full Recovery Expectations (Weeks 6–12)

This is the final stretch of recovery, where your dog regains most strength and returns to normal routines.

• Signs your dog is ready for more activity: You’ll notice improved weight-bearing, stronger muscles, and eagerness to move without limping.
• Reintroducing normal play and routines: Start short play sessions and allow off-leash activity in a safe area. Avoid high-impact jumps until cleared by your vet.
• Final vet check and long-term outcomes: A final evaluation around 10–12 weeks ensures the joint has healed well. X-rays may be taken to assess progress.
• Tips for maintaining joint health after recovery:
  
  • Keep your dog at a healthy weight
  • Provide joint supplements if recommended
  • Stick to a regular low-impact exercise routine

Most dogs enjoy a pain-free, active life after FHO. Stay consistent with care and your dog will likely return to doing the things they love.

FAQs

How long should I restrict my dog after FHO surgery?

Activity should be restricted for at least 6–8 weeks after FHO surgery. Crate rest and controlled leash walks are important during the early healing phase. Your vet will guide you on when to slowly increase activity. Full recovery can take up to 12 weeks, depending on your dog’s progress and comfort level.

What are the best rehab exercises after FHO?

Start with gentle leash walking and passive range-of-motion stretches. As healing progresses, add sit-to-stand drills, incline walking, and later hydrotherapy. Each exercise should be done slowly and carefully. Always follow your vet’s or rehab therapist’s guidance to prevent overuse and promote proper muscle rebuilding.

Can my dog go upstairs during recovery?

No, stairs should be avoided during the first few weeks. They can strain healing muscles and joints. If stairs are unavoidable, use a sling or harness to support your dog. Once your vet approves, short stair use with supervision may be allowed around weeks 4–6 of recovery.

When is hydrotherapy safe to start?

Hydrotherapy can usually begin around week 2 or 3, once the incision is fully healed. It’s a low-impact way to build strength and improve movement. Always get your vet’s approval before starting, and ensure sessions are guided by trained professionals for best results.

What if my dog still limps weeks after surgery?

Some limping is normal in the early stages, especially if your dog hasn’t regained full muscle strength. But if limping continues beyond 6–8 weeks or worsens, consult your vet. It may signal delayed healing, discomfort, or the need for adjusted rehabilitation exercises.

Is it normal for the incision to look bruised?

Yes, mild bruising or slight swelling around the incision is common during the first few days. It should gradually improve. However, if the area becomes red, warm, painful, or oozes pus, contact your vet immediately as these may be signs of infection.

‍

What Is Medial Patellar Luxation (MPL)?

Medial Patellar Luxation (MPL) is a condition where a dog’s kneecap (patella) slips out of its normal groove and moves toward the inside of the leg. This misalignment causes the knee joint to become unstable and painful.

• Knee and mobility impact: When the patella moves out of place, it interferes with the smooth motion of the leg. This makes walking, running, and standing more difficult. Over time, the joint may develop inflammation, arthritis, or muscle loss if left untreated.
• Signs and symptoms: Most owners notice limping, skipping steps, or the dog holding one leg up. Some dogs may show a hopping gait or reluctance to run, climb stairs, or jump. The signs may come and go in mild cases or become more constant as the condition worsens.

Recognizing these symptoms early helps ensure your dog receives proper care before long-term damage sets in. A veterinary exam is needed to confirm MPL and determine its severity.

Understanding MPL Grades and Why They Matter

Veterinarians classify Medial Patellar Luxation (MPL) into four grades based on how easily the kneecap moves out of place and how often it stays there. These grades help guide treatment decisions and predict outcomes.

• Grade I: The kneecap can be manually moved out of place but returns on its own. Dogs may not show clear symptoms and often walk normally.
• Grade II: The patella dislocates on its own but can return manually or with movement. Dogs may show occasional limping or skipping.
• Grade III: The kneecap is out most of the time but can be pushed back into place. Dogs often have lameness or abnormal gait.
• Grade IV: The kneecap is permanently out of place and cannot be returned. Dogs have trouble walking and may show pain or severe limb deformity.

Grades I and some Grade II cases may be managed without surgery. Grades III and IV almost always require surgical correction to prevent long-term joint damage and restore function.

Can Mild Cases Be Managed Without Surgery?

Yes, surgery is not always necessary for every case of Medial Patellar Luxation. Mild cases—especially Grade I and some Grade II—can often be managed successfully with conservative treatment, especially when symptoms are minimal.

• Good candidates for non-surgical care: Small breed dogs under 20–25 pounds, dogs with occasional limping but no consistent pain, or older pets with lower activity levels.
• When surgery may not be needed: If your dog moves normally most of the time, does not show signs of chronic pain, and maintains good muscle strength in the leg.
• Monitoring is key: Dogs with mild MPL should be checked regularly to make sure the condition isn’t getting worse.

Managing mild MPL early can delay or even avoid the need for surgery. However, owners must stay alert for signs of progression, such as frequent limping or reduced activity. Your veterinarian can help determine if surgery is needed later based on your dog’s symptoms and lifestyle.

Non-Surgical Management Options

For dogs with mild MPL or those not ready for surgery, there are several non-surgical options that help reduce pain and support joint function.

• Weight control: Keeping your dog at a healthy weight reduces stress on the knees and slows joint wear.
• Exercise restrictions: Avoid jumping, fast running, or slippery surfaces. Controlled walks and low-impact movement are safer.
• Joint supplements: Products containing glucosamine, chondroitin, or omega-3 fatty acids support cartilage health and reduce inflammation.
• Anti-inflammatory medications: Vets may prescribe NSAIDs to relieve pain and improve movement in flare-up periods.
• Physical therapy: Gentle stretching, strength-building exercises, or laser therapy help maintain muscle tone and balance.
• Hydrotherapy: Swimming or underwater treadmill therapy allows your dog to exercise without putting weight on the joint.

These approaches do not cure MPL, but they often keep symptoms under control, especially in mild or early-stage cases. Regular follow-ups are important to monitor changes in mobility or comfort.

When Surgery Becomes Necessary

Surgery becomes necessary when non-surgical treatments no longer manage symptoms or when the patellar luxation is more severe (Grades III–IV). Early surgery can prevent joint damage, chronic pain, and loss of mobility.

• Signs conservative care isn’t working: Frequent limping, pain during movement, decreased activity, or worsening gait even with rest and medications.
• When surgery is recommended right away: Grade III or IV MPL, kneecap always dislocated, clear signs of pain, or limb deformity. Puppies with severe signs may need early correction to avoid growth issues.
• Risks of delaying surgery: Untreated MPL can lead to arthritis, muscle loss, and worsening joint misalignment. Long-term damage may make surgery and recovery more difficult later.

If your dog struggles to walk or play comfortably, it’s time to discuss surgery. Procedures are generally safe and have a high success rate, especially when done early. Your vet will guide you through the options based on your dog’s condition, age, and lifestyle.

What Happens If MPL Is Left Untreated?

Leaving Medial Patellar Luxation (MPL) untreated can lead to long-term problems in the knee joint. Even if symptoms seem mild at first, the condition often worsens over time.

• Joint degeneration and arthritis: Repeated luxation wears down cartilage, leading to joint inflammation and permanent damage.
• Pain and worsening lameness: As the kneecap slips more often, your dog may limp more, avoid activity, or show signs of constant discomfort.
• Cranial cruciate ligament (CCL) tears: Long-term instability puts added strain on other structures, especially the CCL, increasing the risk of rupture and more serious surgery.

Delaying treatment can turn a manageable condition into a much more complex problem. While mild cases can be monitored, dogs with moderate or severe MPL often benefit from early surgical correction to avoid joint breakdown and pain. Regular vet check-ups help track changes and guide timely intervention.

Surgical Treatment Options for MPL

Several surgical options are available to correct Medial Patellar Luxation, depending on the grade of the condition and your dog’s unique anatomy.

• Trochlear sulcoplasty: The surgeon deepens the groove where the kneecap sits, helping it stay in place during movement.
• Tibial tuberosity transposition (TTT): This procedure moves the bony attachment of the patellar tendon to better align the kneecap with the groove.
• Soft tissue techniques: Tight or loose tissues around the knee are either released or tightened to improve stability.
• Bone corrections (osteotomy): In severe cases with limb deformities, cutting and realigning bones is needed to restore proper function.

These procedures are often combined during surgery to give the best results. The goal is to keep the kneecap stable, reduce pain, and prevent further joint damage. Your vet or surgeon will select the right combination based on X-rays, gait analysis, and physical exam findings.

Recovery and Long-Term Outlook After Surgery

Recovery after MPL surgery involves several weeks of rest, careful monitoring, and gradual return to activity. Most dogs do very well when owners follow post-operative care closely.

• Initial recovery: The first 2 weeks require crate rest and strict activity restriction. Pain medications and anti-inflammatories are typically prescribed.
• Gradual rehab: Controlled leash walks and home exercises start in weeks 3–6. Jumping, running, and stairs are limited until the vet gives clearance.
• Physical therapy: Many dogs benefit from structured rehab, including underwater treadmill, stretching, and muscle-strengthening to rebuild leg function.

Most dogs return to normal or near-normal activity within 8–12 weeks. Long-term outcomes are excellent for most cases, especially if the surgery is done before severe joint damage sets in. With successful surgery and proper care, your dog can enjoy a pain-free, active life again.

Does Breed or Size Affect Surgical Decisions?

Yes, breed and size play a major role in how veterinarians approach MPL treatment. While MPL is most common in small breeds, it can affect larger dogs too.

• Smaller breeds: Dogs like Pomeranians, Chihuahuas, and Yorkies commonly develop MPL and often respond very well to surgical correction.
• Large breeds: Surgery can be more complex due to body weight and bone structure. Outcomes are still good but may require more rehab and monitoring.
• Age and activity level: Younger dogs recover faster and may benefit more from early surgery. Active dogs are often treated sooner to prevent injury to other joints.

Your vet will consider breed, weight, limb alignment, and lifestyle when recommending surgery. Even large dogs can do well with the right surgical plan and consistent follow-up care.

Is Surgery Worth It? Cost vs Outcome

For many dogs, MPL surgery is a long-term investment in comfort and mobility. While the upfront cost can be significant, the benefits are often life-changing.

• Typical cost: MPL surgery ranges from $1,500 to $4,000 per knee depending on location, surgeon experience, and complexity.
• Early intervention saves money: Addressing MPL before it worsens reduces the chance of arthritis or ligament injuries, which require more costly treatment.
• Satisfaction and results: Most owners report high satisfaction. Dogs often return to walking, running, and playing with no pain and minimal limp.

While not every case requires surgery, it’s highly effective in moderate to severe cases or when quality of life is reduced. Discussing options with your vet can help you make a confident decision based on your dog’s needs and your budget.

FAQs

How do I know if my dog needs surgery for MPL?

Your vet will assess the severity (Grade I–IV), signs like limping, pain, or kneecap dislocation, and how much it affects your dog’s daily life. Surgery is usually needed for Grade III or IV, or if conservative care fails. A full exam, gait observation, and X-rays help decide if surgery is necessary.

Is surgery the only option for a Grade II luxating patella?

Not always. Some Grade II cases can be managed with rest, weight control, joint supplements, and physical therapy. But if your dog shows worsening pain or lameness, or the condition doesn't improve, surgery may still be recommended. Your vet will guide the best option based on how your dog responds.

Can a dog live a normal life without MPL surgery?

Mild cases (like Grade I) often don’t need surgery and dogs can live comfortably with conservative care. But moderate or severe cases may get worse without surgery, leading to pain, arthritis, or ligament injuries. A dog’s quality of life depends on how well symptoms are managed over time.

How successful is MPL surgery in dogs?

MPL surgery has a high success rate, especially when done early. Most dogs recover well, with reduced pain and improved mobility. Success depends on the dog’s size, the grade of luxation, and how well post-surgical rehab is followed. Reluxation or complications are rare but possible if care is inconsistent.

How much does MPL surgery cost on average?

The cost of MPL surgery typically ranges from $1,500 to $4,000 per knee, depending on your location, surgeon, and whether one or both knees are affected. Additional costs may include diagnostics, follow-up visits, and physical therapy. Some clinics offer financing or package plans to help manage expenses.

Is MPL surgery more risky in large breed dogs?

Surgery in large breeds may involve more challenges due to body weight and joint structure. While the risk of complications is slightly higher, outcomes are still good with proper surgical technique and rehab. Large dogs may need longer recovery and physical therapy, but many return to normal activity.

‍

What Is Medial Patellar Luxation (MPL)?

Medial Patellar Luxation (MPL) is a condition where a dog’s kneecap (patella) slips out of its normal position inside the femoral groove and moves toward the inside of the leg. This causes pain, limping, or skipping while walking. Over time, it can lead to joint damage or arthritis if not treated.

Commonly Affected Breeds

MPL is more common in small and toy breeds, though large breeds can also be affected.

• Pomeranians
• Yorkshire Terriers
• Chihuahuas
• Miniature and Toy Poodles
• Boston Terriers
• Pekingese
• Shih Tzus
• Some large breeds like Labrador Retrievers and Akitas

In many cases, the condition is inherited and may appear in both legs.

Why Grading Matters for Treatment

MPL is classified into four grades based on how easily the kneecap moves out of place. Grading helps the veterinarian decide the best treatment plan.

• Lower grades may not need surgery and can be managed with lifestyle changes.
• Higher grades often require surgery to correct the joint and improve function.

Understanding the grade is key to choosing the right care and predicting recovery success.

Understanding the MPL Grading System

Grade I Medial Patellar Luxation

In Grade I MPL, the patella can be moved out of place during a physical exam but returns to its normal position on its own. Most dogs do not show obvious signs of pain or discomfort.

Typical signs:

• Intermittent “skipping” gait on one back leg
• Kneecap slips briefly, then goes back into place
• No swelling or pain when resting
• Dogs remain active and playful

Is surgery needed?

• Usually not required.
• Vets often recommend monitoring, weight control, and joint supplements.
• Surgery may be considered if the condition worsens over time.

Most dogs with Grade I live comfortably without surgery, especially if they stay active, lean, and avoid rough play. Early diagnosis helps prevent progression to higher grades.

Grade II Medial Patellar Luxation

In Grade II, the kneecap slips out more often and may stay out until it is manually repositioned. Dogs may limp or have periods of discomfort after exercise.

Common symptoms:

• More frequent skipping or limping
• Patella may remain out for several steps
• Discomfort when running or turning quickly
• Muscle loss may begin over time if not treated

When is surgery considered?

• Surgery is recommended if symptoms worsen or become regular.
• Dogs that limp often or avoid using the leg benefit from correction.
• Joint damage may occur over time if left untreated.

Some dogs with Grade II improve with conservative care, but many eventually need surgery to avoid arthritis and improve leg use.

Grade III Medial Patellar Luxation

With Grade III MPL, the kneecap is out of place most of the time but can be pushed back into the groove during an exam. Dogs often have an abnormal gait and show clear signs of discomfort.

Functional impact:

• Frequent limping or stiffness, especially after activity
• “Bunny hopping” gait or dragging one leg
• Muscle wasting on the affected leg
• Joint swelling or changes in alignment

Surgical recommendation:

• Surgery is strongly recommended to restore leg function.
• If left untreated, arthritis and permanent joint damage may occur.
• Recovery may take longer, but outcomes are usually very good.

Grade III dogs often need both soft tissue and bone procedures. Timely surgery greatly improves their quality of life and movement.

Grade IV Medial Patellar Luxation

Grade IV is the most severe form. The patella is always out of place and cannot be manually moved back into position. The leg often appears twisted or underdeveloped due to poor use.

Severe signs:

• Constant lameness or inability to use the leg
• Abnormal bone shape and knee structure
• Significant pain, joint swelling, or deformity
• Difficulty standing, sitting, or walking normally

Need for advanced correction:

• Advanced surgery is required, often involving bone realignment.
• In some cases, staged procedures are needed to fully correct the limb.
• Recovery is longer and more closely monitored.

Even though Grade IV is complex, many dogs improve with surgery. While some may still have a limp, pain is usually reduced and mobility increases. Early treatment offers the best chance for comfort and stability.

How Vets Diagnose the Grade of MPL

Veterinarians use a mix of hands-on exams and imaging to diagnose the grade of Medial Patellar Luxation (MPL). The goal is to check how easily the kneecap moves out of place and how stable the joint is during movement.

Key Diagnostic Methods

• Physical exam: The vet checks for signs of discomfort, joint looseness, and muscle loss in the hind legs.
• Manual luxation test: While the dog is relaxed, the vet gently moves the patella to see if it slides out of place, how easily it moves, and whether it returns to the groove.
• Radiographs (X-rays): Used to check bone shape, joint alignment, and other knee problems like arthritis or bone rotation.
• Limb alignment studies: In advanced cases, special X-rays help measure bone angles and rotation, especially for surgical planning in Grade III or IV.

Accurate grading is key to choosing the right treatment. Early diagnosis allows for better planning and can prevent the condition from getting worse over time.

Signs and Symptoms That Help Determine the Grade

MPL affects dogs differently depending on the grade. Symptoms often start mild but can worsen if the kneecap slips more often or stays out.

Common Symptoms by Grade

• Grade I: Mild, with occasional skipping or brief lameness. The dog usually walks normally between episodes.
• Grade II: More frequent skipping or limping. Some dogs start avoiding exercise or show leg stiffness after activity.
• Grade III: Constant limping or altered gait. Dogs may hop with both legs or show signs of pain during touch or movement.
• Grade IV: Severe dysfunction. Dogs often drag one leg or walk with bent knees. The limb may look twisted or underdeveloped.

Other Key Signs

• Skipping or bunny-hopping gait: Common in Grades II–III
• Bilateral signs: Both knees are often affected in small breeds
• Unilateral signs: Seen more often when injury causes MPL on one side

Observing the dog’s movement helps the vet match symptoms with the correct MPL grade and decide on treatment.

Treatment Options by Grade

Treatment for MPL depends on the grade, the dog’s age, weight, and symptoms. Lower grades may improve with non-surgical care, but higher grades usually need surgery.

Conservative Management (Grade I–II)

• Weight control
• Joint supplements
• Physical therapy
• Limiting jumping or rough play
• Pain medication, if needed

Dogs with mild signs often live comfortably without surgery if their condition stays stable.

Surgical Treatment (Grade II–IV)

When symptoms worsen or the patella stays out often, surgery is usually recommended.

• Trochlear sulcoplasty: Deepens the groove where the kneecap sits
• Tibial tuberosity transposition (TTT): Realigns the patellar tendon
• Soft tissue adjustments: Tighten or release tissues to improve tracking

Advanced Surgeries

• Needed for Grade III–IV
• May include bone cutting, plate fixation, or staged corrections
• Tailored to the dog's unique joint shape and deformity

Surgical plans vary, but the goal is always to keep the patella in place and restore comfortable movement.

Prognosis Based on Grade

The long-term outlook after MPL surgery is usually very good, especially when the condition is treated early and post-op care is followed closely.

Grade-Based Outcomes

• Grade I–II: Excellent prognosis; many dogs return to full activity and never need surgery
• Grade III: High success rates, but there is a slightly higher risk of reluxation or needing a second procedure
• Grade IV: Outcomes vary depending on joint damage. Dogs often improve, but some may keep a limp or limited motion

Reluxation Risk

• Occurs in about 10–21% of cases
• More common in Grade III and IV
• Risks decrease with proper rehab and weight control

Benefits of Early Treatment

• Helps prevent arthritis and joint damage
• Improves surgical success
• Shortens recovery time

With early diagnosis, a tailored surgical plan, and careful recovery, most dogs live active, pain-free lives after MPL correction.

FAQs

How do vets grade a dog’s patellar luxation?

Vets grade MPL by gently moving the kneecap during a physical exam to see how easily it slips out and whether it goes back into place. They also check how the dog walks and may use X-rays to study bone shape and joint alignment. Grades range from I (mild) to IV (severe and permanent).

What is the difference between Grade I and Grade IV MPL?

Grade I MPL is the mildest form, where the kneecap only slips out during an exam and quickly returns on its own. Dogs usually show no pain or limping. Grade IV is the most severe. The kneecap is always out, cannot be pushed back in, and the leg may look twisted or underused, often needing complex surgery.

Can Grade I MPL become worse over time?

Yes, Grade I MPL can worsen if the dog gains weight, gets injured, or has weak joint support. Over time, the kneecap may start slipping more often, leading to joint wear and pain. Regular checkups, weight control, and joint care can help prevent it from progressing to higher grades.

Is surgery always needed for Grade II MPL?

Not always. Some dogs with Grade II MPL respond well to weight control, joint supplements, and restricted activity. But if the dog shows regular limping, pain, or reduced movement, surgery may be the better option. Your vet will decide based on symptoms, age, and how the joint is behaving.

What happens if MPL is left untreated?

If MPL is not treated, it can lead to chronic pain, joint damage, and arthritis. The dog may limp more often, avoid using the leg, or develop muscle loss. In higher-grade cases, untreated MPL can result in permanent joint deformity or the need for more complex surgery later.

Are some breeds more likely to have higher-grade MPL?

Yes, small breeds like Pomeranians, Chihuahuas, Yorkies, and Toy Poodles are more likely to have MPL, and some may develop higher-grade luxation due to their bone shape and genetics. However, large breeds can also be affected. Early screening in at-risk breeds helps catch problems before they get worse.

‍

What Is Medial Patellar Luxation (MPL)?

Medial Patellar Luxation (MPL) is a knee condition in dogs where the kneecap (patella) slips out of its normal groove on the femur. Instead of staying in place, it moves toward the inside (medial side) of the leg. This can cause pain, limping, or long-term joint damage if not treated.

Grades of MPL

• Grade I: Patella slips out but returns on its own
• Grade II: Patella comes out easily and may stay out sometimes
• Grade III: Patella is out most of the time but can be pushed back in
• Grade IV: Patella is always out and cannot be returned manually

Common Breeds and Risk Factors

• Small breeds like Pomeranians, Chihuahuas, Poodles, and Yorkies
• Genetic traits, shallow femoral grooves, or injury increase the risk

What Does MPL Surgery Involve?

Medial Patellar Luxation (MPL) surgery is done to correct the position of a dog's kneecap. When the patella keeps slipping out of place, it causes pain and changes how your dog walks. Surgery helps keep the kneecap stable and prevents long-term damage to the joint.

Goals of the Procedure

• Keep the patella inside its groove during movement
• Restore normal leg alignment and function
• Reduce pain, limping, and joint wear
• Prevent arthritis and other joint issues in the future

Common Surgical Techniques

Veterinary surgeons choose one or more techniques based on the dog’s grade of MPL and joint shape:

• Trochleoplasty: Deepens the femoral groove so the kneecap stays in place
• Tibial Tuberosity Transposition (TTT): Realigns the patellar tendon by moving a small bone piece
• Lateral Imbrication: Tightens tissue on the outer side of the joint to support the kneecap
• Medial Release: Loosens tight inner tissues that pull the patella out of place

Recovery Timeline in Brief

• Dogs can bear weight in a few days
• Activity must be limited for 6–8 weeks
• Full healing takes about 12–16 weeks, including rehab and follow-ups

Success Rates by MPL Grade

Grade I–II: Highest Success (Up to 100%)

Surgery for Grade I and II MPL cases has the best results. These are mild forms where the kneecap may slip occasionally (Grade I) or more often but still return on its own or with help (Grade II). In both cases, joint anatomy is mostly normal.

• Success rate: Up to 100%
• Common procedures: Soft tissue tightening, medial release, trochleoplasty
• Complication rate: Very low
• Recovery time: 8–12 weeks for full return to normal function

Most dogs regain full use of the leg after healing. They walk and run normally without pain. Surgery at this stage also helps prevent arthritis or worsening joint issues in the future. In many Grade I cases, surgery isn’t even needed unless symptoms worsen.

Follow-up care includes rest, anti-inflammatory meds, and light rehab. These dogs typically do not need revision surgery, and the long-term outcome is excellent. Early treatment means faster recovery and fewer risks overall.

Grade III: High Success (90–100%) but Higher Recurrence

Grade III MPL is more advanced. The patella stays out of place most of the time but can be manually repositioned. Dogs often show more lameness, and their joint structure may need stronger correction.

• Success rate: Around 90–100%
• Common procedures: Trochleoplasty, TTT, lateral imbrication, medial release
• Complication risk: Moderate, especially reluxation
• Recovery time: 10–14 weeks, including rehab and checkups

Surgery often involves both bone and soft tissue work. In some dogs, the joint may still loosen over time, leading to partial luxation again. This is more likely if recovery is rushed or if the dog is very active during healing.

While most dogs return to near-normal movement, some may show minor stiffness or a mild limp, especially during exercise. A small number of dogs may need revision surgery later in life.

With proper surgical planning, weight control, and good rehab, most Grade III cases have strong outcomes and can return to a happy, active lifestyle.

Grade IV: Variable Success (64–93%)

Grade IV MPL is the most severe form. The kneecap is always out of place and cannot be pushed back manually. Dogs often have serious skeletal changes, like rotated tibias or shallow grooves, which require more complex surgery.

• Success rate: Ranges from 64% to 93%
• Common procedures: TTT, deep trochleoplasty, rotational correction, staged surgeries
• Complication risk: High, especially reluxation or implant failure
• Recovery time: 12–16 weeks or longer, depending on case complexity

These surgeries are more challenging and may involve multiple steps. In some cases, staged correction is needed to slowly fix the bone alignment over time. Healing is slower, and strict rest is very important to avoid complications.

Some dogs improve but may not regain full, normal motion. A mild limp or stiffness can remain, especially in older dogs or those with long-standing luxation. However, pain relief and improved comfort are still strong outcomes.

With skilled surgery, proper follow-up, and careful rehab, many Grade IV dogs live more comfortable, mobile lives—even if their function isn't perfect.

Complication and Recurrence Rates

While most dogs recover well after Medial Patellar Luxation (MPL) surgery, there are some risks to be aware of. The chance of complications or the kneecap slipping again depends on the grade of MPL, the dog’s age, the surgeon’s technique, and how well post-surgery care is followed.

Average Rates

• Recurrence (reluxation) rate: 10–21%
• Major complication rate: 16–24%

These numbers are higher in dogs with Grade III and IV luxation, where the joint is more unstable or the bone structure is more deformed.

Common Complications

• Swelling or seroma: Fluid may collect near the incision site
• Implant issues: Pins or wires used in surgery may move or loosen
• Infection: Can happen at the wound site if not kept clean
• Joint stiffness: Especially if rest is not followed properly
• Recurrence: The patella may slip out again if healing is poor

Rare but Serious Outcomes

• Nerve damage or long-term lameness
• Poor bone healing in very active or older dogs
• Amputation (very rare): Only needed if the leg becomes non-functional due to severe infection or failure

Proper rest, weight control, and follow-up care reduce most risks.

Factors That Affect Surgical Success

Not all MPL surgeries have the same outcome. Several key factors can affect how well a dog recovers and how stable the knee stays after surgery.

Key Factors

• Age of the dog: Younger dogs tend to heal faster and adapt better. Older dogs may have slower recovery and higher arthritis risk.
• Weight/body condition: Overweight dogs have more pressure on their joints, which increases the risk of complications and slower healing.
• Other joint issues: Dogs with a torn cranial cruciate ligament (CCL) or hip problems may need more complex surgery.
• Breed-related anatomy: Some breeds have shallow grooves or bone rotation, making surgery more difficult.
• Unilateral vs bilateral surgery: Dogs with both knees affected (bilateral MPL) may take longer to recover, especially if both surgeries are done together.

Each of these factors plays a role in the dog’s outcome. A well-planned surgery combined with personalized care improves the success rate, even in more complex cases. Pre-surgical exams and imaging help identify these factors early so the treatment can be tailored to each dog’s needs.

Long-Term Outcomes and Owner Satisfaction

Most dogs that undergo MPL surgery enjoy long-lasting relief from pain and improved movement. Long-term success depends on the surgery quality and how well the dog is cared for afterward.

What Owners Can Expect Long-Term

• Pain control: Most dogs are more comfortable and pain-free after healing. Long-term pain is rare if the joint is stable.
• Activity levels: Many dogs return to normal activity—walking, running, and playing—within 3–4 months.
• Satisfaction rates: Over 90% of owners report high satisfaction with the surgery, especially in Grades I–III.

Some dogs may still show mild stiffness or avoid certain movements, especially if they had a high-grade luxation or other joint conditions. Regular exercise, weight control, and avoiding intense jumping or rough play help preserve joint health over time.

Overall, MPL surgery has a strong track record of improving quality of life. Dogs move more freely, show less pain, and become more active after recovery. When paired with proper follow-up care, most dogs remain stable for many years after surgery.

How to Maximize the Chances of a Successful Outcome

Good surgical technique is just one part of MPL recovery. What happens after surgery is just as important for a full and lasting recovery.

Key Steps for Better Results

• Post-op care: Strict crate rest for 6–8 weeks is critical. It prevents implant movement and allows the joint to heal properly.
• Rehabilitation: Gentle rehab like controlled leash walks, underwater treadmill, or physiotherapy helps regain strength and range of motion.
• Follow-ups: Regular vet checkups ensure healing is on track. X-rays may be needed to confirm bone healing and implant position.

Owners play a big role in the recovery process. Keeping the dog calm, using medications as prescribed, and following rehab steps all support better outcomes. It’s also important to avoid running, jumping, or stairs until your vet gives the all-clear.

Feeding a balanced diet and keeping your dog at a healthy weight also reduces joint stress. With the right support at home and guidance from your vet, your dog has the best chance to heal fully and return to an active, pain-free life.

Conclusion

Medial Patellar Luxation (MPL) surgery is a highly effective treatment for dogs with kneecap instability. With proper surgical planning and careful post-op care, most dogs return to normal or near-normal function. Success rates are especially high in Grade I–III cases, and even dogs with Grade IV can show major improvement.

While complications are possible, they are often manageable with early attention. Owners who follow vet instructions—especially crate rest and rehab—help their dogs heal faster and avoid reluxation. With patience and proper care, most dogs enjoy a more active, pain-free life after surgery.

FAQs

What is the average success rate for MPL surgery in dogs?

The success rate for MPL surgery is high. For Grade I–III cases, it ranges from 90% to 100%. Grade IV cases have a slightly lower success rate, between 64% and 93%, due to complex joint changes. Most dogs regain good function and live comfortably with proper care and follow-up.

Does the grade of MPL affect the surgery results?

Yes, the grade of MPL directly affects the surgery outcome. Lower grades (I–II) have simpler issues and near-perfect success. Grade III surgeries are more complex but still have high success. Grade IV often needs advanced correction and has a higher risk of complications, though many dogs still improve significantly.

What are the chances of MPL coming back after surgery?

The chance of the kneecap slipping again, called reluxation, is around 10–21%. This depends on the grade of MPL, the dog’s activity level, and how closely post-op care is followed. Proper rest, weight control, and vet follow-ups can lower this risk and help keep the knee stable.

How long does it take for a dog to recover from MPL surgery?

Most dogs begin walking within a few days but need 6–8 weeks of crate rest. Full recovery can take 3–4 months, especially for higher-grade surgeries. During this time, rehab and regular checkups help rebuild strength and ensure healing is on track.

Can my dog walk normally after MPL surgery?

Yes, most dogs can walk and even run normally after MPL surgery. Once healing is complete, they often return to normal activity levels. Minor stiffness or a limp may remain in rare cases, especially in Grade IV or older dogs, but pain and lameness usually improve.

Is MPL surgery safe for older or overweight dogs?

MPL surgery can be done safely in older or overweight dogs, but the risks are slightly higher. These dogs may heal slower or face more stress on the joint. With proper planning, pain management, and weight control, they can still have excellent results and better comfort long-term.

‍

Femoral Head Ostectomy (FHO) is a surgery performed to relieve severe hip pain in dogs by removing the damaged head and neck of the thigh bone. This procedure stops painful bone-on-bone contact and allows the formation of a “false joint,” helping dogs move more comfortably.

Understanding the recovery process after FHO surgery is important for dog owners. Recovery involves rest, pain management, and physical therapy, all crucial to help your dog regain strength and mobility. Knowing what to expect helps you provide better care and support during healing.

Being prepared for the recovery timeline, activity restrictions, and signs to watch for ensures your dog has the best chance for a smooth, successful recovery. This knowledge also reduces stress for both you and your dog, improving overall comfort and quality of life after surgery.

Hospital Stay and Immediate Care

After Femoral Head Ostectomy (FHO) surgery, most dogs stay in the hospital for one to two days. This allows veterinarians to monitor your dog closely as they wake up from anesthesia and manage any immediate post-surgery needs.

• Length of stay: The hospital stay usually lasts 24 to 48 hours, depending on your dog’s condition and how well they recover from anesthesia.
• Pain management: Vets provide pain relief through medications such as non-steroidal anti-inflammatory drugs (NSAIDs) and opioids if needed. Managing pain early is essential to keep your dog comfortable and encourage gentle movement.
• Medications: Your dog may also receive antibiotics to prevent infection and muscle relaxants to ease stiffness.
• Protecting the incision: To stop your dog from licking or biting the surgical site, an Elizabethan collar (cone) or alternative protective device is used. This prevents infection and helps the wound heal properly.

Close monitoring and early pain control during the hospital stay set the stage for a smoother, less painful recovery once your dog returns home.

Post-Surgery Care at Home

After Femoral Head Ostectomy (FHO) surgery, restricted activity and cage rest are vital to ensure proper healing. Limiting your dog’s movement helps prevent strain on the surgical site and reduces the risk of complications.

• Restricted activity: Keep your dog confined to a small, quiet space or crate to avoid jumping, running, or climbing stairs for at least 6 to 8 weeks. Use a leash for short bathroom breaks only.
• Wound care: Keep the surgical incision clean and dry. Avoid bathing your dog until the vet says it’s safe. If cleaning is needed, use mild antiseptic solutions as directed by your vet, and never apply harsh chemicals.
• Watch for signs: Check the incision daily for swelling, bruising, redness, discharge, or a foul odor. Some bruising and mild swelling are normal, but worsening symptoms may indicate infection.
• Prevent licking: Use an Elizabethan collar (cone) to stop your dog from licking or biting the wound, which can cause infection and delay healing.

Careful attention to post-surgery care supports healing and helps your dog recover comfortably at home.

Recovery Timeline and Activity

Recovery after Femoral Head Ostectomy (FHO) surgery is gradual and requires careful management of activity to ensure healing and prevent complications.

• Gradual reintroduction of walking: Short, gentle leash walks usually begin about 1 to 2 weeks after surgery, depending on your vet’s advice. Start with 5 to 10 minutes and slowly increase duration as your dog gains strength and comfort.
• Activity restrictions: Avoid running, jumping, climbing stairs, or rough play for at least 6 to 8 weeks. Controlled, low-impact movement protects the surgical site and supports healing.
• Physical therapy: Rehabilitation exercises help rebuild muscle strength, improve joint mobility, and reduce stiffness. Common therapies include passive range-of-motion exercises, underwater treadmill sessions, and gentle stretching.
• Owner’s role: Following your vet’s guidance on exercise and therapy is crucial. Consistent, supervised rehab improves recovery speed and overall outcome.

With proper timing and controlled activity, most dogs regain good function and mobility within 2 to 3 months after FHO surgery. Rehabilitation plays a key role in restoring quality of life.

Monitoring and Follow-up

Scheduled veterinary visits and follow-up care are essential parts of recovery after Femoral Head Ostectomy (FHO) surgery. These appointments help your vet monitor healing progress and catch any complications early.

• Scheduled visits: Your vet will usually schedule check-ups at regular intervals, such as 2 weeks, 6 weeks, and a few months post-surgery. These visits allow close monitoring of your dog’s recovery and adjustment of treatment plans if needed.
• X-rays: Follow-up X-rays help the vet assess the surgical site, check the formation of the “false joint,” and ensure there are no signs of infection or complications. X-rays provide valuable information about bone healing and joint stability.
• What vets look for: During exams, vets check your dog’s pain levels, mobility, muscle strength, and incision healing. They also evaluate the range of motion and watch for signs of swelling, infection, or abnormal joint movement.
• Adjusting care: Based on findings, your vet may recommend changes to medications, physical therapy, or activity levels to support optimal healing.

Regular monitoring and follow-up help ensure your dog’s recovery stays on track, leading to better long-term outcomes and comfort.

Expected Outcomes and Long-Term Recovery

Healing after Femoral Head Ostectomy (FHO) surgery typically takes 8 to 12 weeks. During this time, the body remodels the area where the femoral head was removed, forming a fibrous “false joint” that cushions movement.

• Healing timeline: Bone remodeling and tissue healing improve gradually, with most dogs showing significant progress within two to three months. Muscle strength and joint flexibility increase with physical therapy and controlled exercise.
• Pain and mobility improvements: Most dogs experience substantial pain relief soon after surgery, allowing them to walk, run, and play more comfortably. Mobility steadily improves as the false joint adapts and muscles rebuild.
• Possible permanent limp or altered gait: Some dogs may retain a slight limp or altered gait due to changes in leg length, muscle strength, or joint mechanics. This is usually mild and does not significantly affect quality of life.

With proper care and rehabilitation, FHO surgery offers excellent long-term benefits. Most dogs regain active, pain-free lives, enjoying improved comfort and mobility for years after surgery.

Owner’s Role in Recovery

Owners play a vital role in supporting their dog’s recovery after Femoral Head Ostectomy (FHO) surgery. Your care and attention directly impact how smoothly and quickly your dog heals.

• Monitoring progress: Observe your dog’s movement, appetite, and behavior daily. Watch for signs of pain, swelling, or changes in walking. Keeping a journal can help track improvements or issues to share with your vet.
• Activity restrictions: Strictly follow your vet’s guidelines on limiting your dog’s activity. Prevent jumping, running, or climbing stairs until cleared by the vet. Controlled leash walks should gradually increase as advised.
• Medication compliance: Administer all prescribed medications on time, including pain relief and antibiotics. Proper medication helps control discomfort and prevents infection.
• Supporting rehab: Assist with physical therapy exercises at home as instructed. Gentle stretching and muscle strengthening aid in restoring mobility and strength.
• Providing a safe environment: Create a calm, comfortable space with non-slip surfaces and easy access to essentials.

By staying attentive and following vet instructions, you give your dog the best chance for a full, comfortable recovery and a return to an active life.

Conclusion

Recovery after Femoral Head Ostectomy (FHO) surgery involves patience, careful management, and supportive care. You can expect your dog to gradually regain strength and mobility over 8 to 12 weeks, with improvements in pain and activity levels. Strict activity restrictions, proper medication, and physical therapy are essential for a smooth recovery.

Most dogs adapt well to the changes, forming a “false joint” that allows comfortable movement without pain. While some may have a slight limp or altered gait, the overall quality of life usually improves significantly.

With your dedication and your vet’s guidance, FHO surgery offers excellent long-term benefits. Your dog can enjoy a happier, more active life free from chronic hip pain. Early diagnosis, proper post-surgery care, and rehabilitation are key to achieving the best possible outcomes.

‍

If your dog is showing signs of pain or trouble moving their hip, it might be time to consider a surgery called Femoral Head Ostectomy (FHO). This surgery helps dogs with serious hip problems feel better and walk more easily. Knowing the signs your dog needs FHO can help you act early and improve their quality of life.

Signs Your Dog Might Need Femoral Head Ostectomy

Recognizing the signs early helps ensure your dog receives timely treatment for painful hip conditions that may require Femoral Head Ostectomy (FHO) surgery.

1. Difficulty Walking or Limping

Limping or difficulty walking is one of the most obvious signs your dog might need FHO surgery. When the hip joint is painful or damaged, your dog will try to avoid putting weight on the affected leg.

• Your dog may limp continuously or only after exercise.
• Favoring one leg over the other helps reduce pressure and pain in the hip.
• Difficulty walking may present as slow, hesitant steps or reluctance to move.

This limping indicates that the hip joint is not functioning properly due to pain, arthritis, fracture, or other damage. Persistent limping despite rest or medication is a strong sign that surgical intervention like FHO could be necessary.

2. Abnormal Gait or Favoring One Leg

An abnormal gait means your dog’s walking pattern changes because of discomfort or weakness. Dogs with hip problems may shift their weight unevenly, causing visible changes in how they move.

• Your dog may “swing” the affected leg or take shorter steps on that side.
• Uneven weight distribution may cause limping or skipping.
• The gait may look unbalanced or awkward, especially after activity.

These changes result from pain or instability in the hip joint. Abnormal gait often worsens over time and is a clear signal to consult your vet for possible surgery.

3. Loss of Weight-Bearing on the Affected Leg

Loss of weight-bearing means your dog refuses to put any weight on the painful leg. This is a severe sign of hip dysfunction and pain.

• Your dog may hold the leg completely off the ground while standing or walking.
• This can occur suddenly or develop gradually with worsening discomfort.
• Loss of weight-bearing leads to muscle weakness and further mobility issues.

When your dog stops using the leg due to pain, it often indicates advanced joint damage requiring surgical treatment such as FHO for pain relief and function restoration.

4. Persistent Hip Pain or Discomfort

Persistent hip pain affects your dog’s quality of life and is a common reason for FHO surgery.

• Your dog may show signs of discomfort such as whining or reluctance to move.
• Pain might be constant or worsen after activity.
• Hip pain reduces interest in walks, play, and normal activities.

Ongoing pain means conservative treatments are not controlling the condition, and surgery may be the best option to restore comfort and mobility.

5. Decreased Activity or Reluctance to Play

Changes in activity level are often one of the first signs owners notice when their dog is in pain.

• Your dog may avoid running, jumping, or climbing stairs.
• Reduced playfulness and slower movements indicate discomfort.
• Reluctance to exercise can lead to weight gain and muscle loss.

This behavior change shows your dog is trying to avoid pain, which may signal the need for surgical intervention like FHO.

6. Stiffness in the Hip Joint, Especially After Rest

Stiffness after rest or sleep is common in dogs with hip joint problems.

• Your dog may be slow to stand or walk after naps.
• The hip may feel tight or rigid, limiting movement temporarily.
• Stiffness often improves with gentle activity but returns after resting.

This stiffness indicates joint inflammation or damage, which may require surgery if it significantly impacts mobility.

7. Pain When the Hip Is Manipulated or Touched

During veterinary exams, pain responses when the hip is moved or touched can confirm joint problems.

• Vets check for tenderness by gently manipulating the hip joint.
• Pain during these tests often correlates with arthritis, fractures, or hip dysplasia.
• A painful response supports the need for further treatment or surgery.

This exam finding helps vets decide if FHO surgery is appropriate for your dog’s condition.

8. Limited Range of Motion in the Hip

A reduced ability to move the hip joint shows stiffness and pain.

• Your dog may struggle to fully extend or flex the leg.
• Limited motion causes difficulty in walking, running, or climbing.
• This restriction often worsens over time without treatment.

Limited range of motion is a key symptom indicating severe joint damage that may benefit from FHO surgery.

9. Muscle Loss or Atrophy in the Affected Leg

Muscle wasting happens when a dog stops using the painful leg regularly.

• You may notice the leg looks thinner or weaker compared to the other side.
• Muscle loss reduces joint support and slows recovery.
• Atrophy often signals chronic discomfort and long-term mobility issues.

Muscle loss is a serious sign that conservative care is no longer enough, and surgical options should be considered.

10. Chronic Lameness Not Improving Over Time

Lameness that does not improve with rest or treatment indicates the need for further evaluation.

• Persistent limping despite medication or physical therapy shows worsening hip disease.
• Chronic lameness reduces your dog’s activity and quality of life.
• This symptom often leads vets to recommend FHO surgery for pain relief.

Ignoring ongoing lameness can cause further joint damage and pain.

11. Joint Instability or Looseness Detected by the Vet

During exams, vets may find instability or looseness in the hip joint.

• The hip may feel unstable or shift abnormally during manipulation.
• Joint instability increases pain and risk of further injury.
• This finding supports surgical intervention to stabilize the joint and relieve pain.

Hip instability is often a clear reason to consider FHO surgery.

12. Reduced Quality of Life Due to Hip Issues

Chronic hip pain and mobility problems can greatly reduce your dog’s happiness.

• Dogs may become withdrawn, less playful, and reluctant to exercise.
• Pain and difficulty moving affect daily activities like walking or climbing stairs.
• Improving quality of life is a primary goal of FHO surgery.

If hip problems interfere with your dog’s enjoyment of life, surgery may provide relief and restore activity.

When to Consult Your Veterinarian About FHO Surgery

Early consultation with your veterinarian is essential if you notice signs of severe hip pain or mobility issues in your dog. Prompt veterinary evaluation helps diagnose the problem accurately and determine if Femoral Head Ostectomy (FHO) surgery is necessary.

• Importance of early consultation: Early vet visits can catch hip conditions before they worsen, improving treatment options and outcomes. Waiting too long may lead to increased pain, joint damage, and muscle loss.
• Diagnostic steps: Your vet will perform a physical exam to assess pain, joint stability, and range of motion. They will also recommend diagnostic imaging like X-rays to evaluate the hip joint’s condition.
• Treatment planning: Based on findings, the vet discusses conservative care options and, if needed, explains the benefits and risks of FHO surgery.
• Ongoing monitoring: Even if surgery isn’t immediately required, regular vet check-ups help track progression and adjust treatment plans.

Consulting your vet early ensures your dog receives timely care, reducing discomfort and helping maintain a good quality of life. Early diagnosis and intervention are key to successful management of hip problems.

How Veterinarians Diagnose the Need for FHO

Veterinarians use a combination of diagnostic tools and physical exams to determine if Femoral Head Ostectomy (FHO) surgery is the best option for your dog.

• Physical exams: The vet assesses your dog’s hip for pain, swelling, decreased range of motion, and instability. They watch how your dog walks and moves to identify signs of discomfort or limited mobility.
• X-rays: Radiographs provide a clear image of the hip joint, showing bone damage, arthritis, fractures, or deformities. X-rays are essential to confirm the severity of the problem and help plan treatment.
• Additional imaging: In some cases, vets may use advanced imaging such as CT scans or MRI to get detailed views of the joint and surrounding tissues.
• Evaluating symptoms: Vets also consider your dog’s history, including persistent limping, pain levels, and response to previous treatments.

Based on these findings, the vet decides if FHO surgery will relieve pain and improve your dog’s quality of life. Early diagnosis ensures timely intervention and better recovery outcomes. Working closely with your vet helps develop a tailored treatment plan that meets your dog’s specific needs.

• Owner’s role: Following your vet’s post-operative care instructions and attending follow-up visits are critical to a smooth recovery.

Most dogs adapt well to the changes and regain comfortable mobility, making FHO a highly effective solution for many painful hip conditions.

FAQs About Femoral Head Ostectomy (FHO) Surgery

How long does it take for a dog to recover from FHO surgery?

Recovery from FHO surgery typically takes 6 to 12 weeks. During this time, your dog needs restricted activity and physical therapy to rebuild muscle strength and improve joint mobility. Full recovery may continue over several months depending on the dog’s size, health, and rehabilitation efforts.

Is FHO surgery painful for dogs?

FHO surgery is performed under general anesthesia, so your dog won’t feel pain during the operation. After surgery, veterinarians prescribe pain medications to keep your dog comfortable while healing. Proper pain management is essential for recovery and helps your dog remain calm and active during rehabilitation.

What dogs are good candidates for FHO surgery?

Small to medium-sized dogs with severe hip pain caused by arthritis, fractures, hip dysplasia, or trauma are good candidates for FHO. Dogs who do not respond well to conservative treatments or other surgeries may also benefit. Your vet will evaluate your dog’s overall health and mobility to decide if FHO is suitable.

Can large dogs undergo FHO surgery?

Large dogs can have FHO surgery, but recovery can be more challenging due to their weight putting extra pressure on the new joint. For bigger dogs, vets often recommend alternatives like total hip replacement, which may provide better long-term mobility and comfort.

What are the risks of FHO surgery?

Risks include infection, muscle atrophy, decreased joint motion, and persistent limping. These risks are minimized by following post-operative care instructions closely, including medication, activity restriction, and physical therapy. Regular vet check-ups help identify and manage any complications early.

How does FHO surgery help improve mobility?

FHO surgery removes the damaged femoral head, eliminating painful bone-on-bone contact. The body forms a fibrous “false joint” that cushions the hip and allows pain-free movement. Combined with rehab, this improves your dog’s ability to walk, run, and enjoy daily activities comfortably.

Understanding FHO Surgery

Femoral Head Ostectomy (FHO) is a surgical procedure where the head and neck of the thigh bone (femur) are removed. This surgery is done to relieve severe pain caused by hip problems like arthritis, fractures, or hip dysplasia.

FHO helps dogs by eliminating the painful bone-on-bone contact inside the hip joint. After surgery, the body forms a “false joint” made of fibrous tissue, which cushions the area and allows more comfortable movement. Although it’s not a normal joint, this new structure reduces pain and improves mobility.

This surgery is often recommended when other treatments like medication or physical therapy have not worked. It allows dogs to regain the use of their leg and live with less discomfort. FHO can be especially helpful for dogs with severe hip damage or those who cannot have more complex surgeries like total hip replacement.

How Veterinarians Diagnose the Need for FHO Surgery

Veterinarians use a combination of physical exams and diagnostic imaging to determine if Femoral Head Ostectomy (FHO) surgery is needed for your dog.

• Physical exam: The vet will assess your dog’s hip joint by checking for pain, swelling, decreased range of motion, and signs of lameness or instability. They will observe how your dog walks and moves to identify discomfort or limited mobility.
• Diagnostic imaging: X-rays are essential to see the condition of the hip joint, including bone damage, arthritis, fractures, or deformities. These images help confirm the diagnosis and guide treatment decisions.
• Signs and symptoms: Dogs showing severe hip pain, persistent limping, difficulty standing or walking, and poor response to medication or physical therapy are often evaluated for surgery.
• Additional tests: In some cases, advanced imaging like CT or MRI may be used for detailed views of the joint structures.

After evaluating these findings along with your dog’s age, size, and overall health, the vet decides if FHO surgery is the best option to relieve pain and improve mobility. Early diagnosis helps plan effective treatment and improve outcomes.

Medical Conditions That Indicate FHO Surgery

Femoral Head Ostectomy (FHO) surgery is often recommended for dogs suffering from specific medical conditions that cause severe hip pain and joint damage.

• Hip dysplasia and severe arthritis: Hip dysplasia is a genetic condition where the hip joint forms abnormally, leading to arthritis and chronic pain. When arthritis becomes severe, FHO can relieve pain by removing the damaged femoral head.
• Traumatic hip injuries: Fractures or dislocations of the femoral head or neck caused by accidents or trauma may require FHO if the bones cannot be repaired. This surgery helps restore comfort and function.
• Legg-Calve-Perthes disease: This condition causes the femoral head to deteriorate (necrosis) due to poor blood supply. FHO removes the damaged bone to eliminate pain and improve mobility.
• Degenerative joint disease in older dogs: Age-related joint wear and tear can cause chronic hip pain. When other treatments fail, FHO can improve quality of life by reducing discomfort and increasing mobility.

Your vet will assess these conditions through exams and imaging to determine if FHO is the best surgical option for your dog’s specific needs.

When Conservative Treatments Are Not Enough

Conservative treatments like medication, rest, and physical therapy are often the first steps in managing hip problems in dogs. However, these approaches may not always provide enough relief.

• Medication failure: Pain relievers and anti-inflammatory drugs can reduce discomfort temporarily, but if your dog continues to show pain or limping, medication alone may not be sufficient.
• Rest and activity modification: Limiting activity can help reduce stress on the hip joint, but persistent discomfort despite rest indicates the need for further intervention.
• Physical therapy limitations: While rehab exercises strengthen muscles and improve joint function, some dogs do not respond well enough to prevent ongoing pain or mobility issues.

When pain and limited mobility continue despite these treatments, it suggests the hip joint damage is severe. At this stage, Femoral Head Ostectomy (FHO) surgery may be recommended to relieve pain and improve quality of life.

Your vet will carefully evaluate your dog’s response to conservative care before suggesting surgery, ensuring that FHO is the best option for lasting relief and better mobility. Early surgical intervention can prevent further decline and discomfort.

Ideal Candidates for FHO Surgery

Femoral Head Ostectomy (FHO) surgery is best suited for certain groups of dogs based on their size, health, and response to other treatments.

• Small to medium-sized dogs: FHO works especially well for dogs under 50 pounds. Their lighter weight allows the “false joint” formed after surgery to support movement effectively, leading to better recovery and mobility.
• Dogs with poor response to previous treatments: If your dog has had medication, physical therapy, or other hip surgeries without sufficient pain relief or improvement, FHO may be the next best step to address ongoing discomfort.
• Dogs with significant reduction in quality of life: When hip pain severely limits your dog’s ability to walk, run, play, or enjoy daily activities, surgery can greatly improve comfort and function.

Vets consider factors like your dog’s age, overall health, activity level, and severity of joint damage when recommending FHO. While FHO may not be suitable for every dog, it offers excellent pain relief and improved mobility for many. Discussing your dog’s specific situation with your vet helps ensure the best treatment choice.

FHO Surgery as an Alternative to Total Hip Replacement

Total hip replacement (THR) is a highly effective surgery that replaces the entire hip joint with an artificial implant. However, THR may not always be feasible or affordable for every dog and owner.

• When THR is not feasible: Some dogs, especially smaller breeds or those with certain health issues, may not be good candidates for THR due to surgical complexity or recovery demands.
• Cost considerations: THR is usually more expensive than Femoral Head Ostectomy (FHO), making FHO a practical option for many owners seeking pain relief for their dogs.

FHO is a less invasive salvage procedure that removes only the damaged femoral head and neck, reducing pain and improving mobility without the need for artificial implants.

• Benefits of FHO: It generally has a shorter surgery time, fewer risks, and a good success rate, especially in smaller dogs. The formation of a “false joint” allows dogs to regain comfortable movement.

While THR can provide better long-term joint function for some, FHO remains a valuable, effective alternative for dogs needing pain relief with fewer surgical demands.

Expected Outcomes and Quality of Life Improvements

Femoral Head Ostectomy (FHO) surgery significantly improves pain and mobility in dogs suffering from severe hip problems. By removing the damaged femoral head and neck, FHO eliminates painful bone-on-bone contact, allowing dogs to move more comfortably.

• Pain relief: Most dogs experience a noticeable reduction in hip pain soon after surgery, which helps them regain willingness to walk, run, and play.
• Improved mobility: As muscles strengthen and the “false joint” forms, dogs regain better use of their leg, leading to a more active and happier life.
• Adaptation: Dogs naturally adjust to the new joint structure, often returning to normal activities with minimal discomfort.

Post-surgery rehabilitation plays a crucial role in maximizing these benefits. Physical therapy helps rebuild muscle strength, improve flexibility, and support joint stability. Controlled exercise and guided rehab reduce stiffness and prevent muscle loss, speeding recovery.

With proper care and rehab, most dogs enjoy a significant improvement in quality of life after FHO surgery, living comfortably and actively without the pain caused by their damaged hip joint.

Conclusion

Femoral Head Ostectomy (FHO) is a valuable surgical option for dogs suffering from severe hip pain caused by conditions like arthritis, fractures, or hip dysplasia. It relieves pain by removing the damaged femoral head, stopping painful bone-on-bone contact. This surgery improves mobility and helps dogs regain comfort, especially when conservative treatments have failed.

FHO is often recommended for small to medium-sized dogs or those that cannot undergo more complex surgeries like total hip replacement. The formation of a “false joint” allows dogs to move with less pain and better function.

Recovery and rehabilitation are important for the best results. If your dog shows signs of hip pain or difficulty moving, consulting your vet early is key. Personalized advice ensures the right treatment plan for your dog’s specific needs, helping them live a happier, more comfortable life.

FAQs

What dogs are the best candidates for FHO surgery?

Small to medium-sized dogs are the best candidates for FHO surgery because their lighter weight allows easier adaptation to the “false joint.” Dogs that have severe hip pain from arthritis, fractures, or hip dysplasia, and those who do not respond to conservative treatments, are also good candidates.

How long does recovery take after FHO surgery?

Recovery after FHO surgery usually takes 6 to 12 weeks. During this time, dogs need restricted activity and physical therapy to rebuild muscle strength and improve joint mobility. Full recovery can take several months depending on the dog’s size and health.

Can large dogs benefit from FHO surgery?

Large dogs can have FHO surgery, but recovery is often more challenging due to their weight. The “false joint” must support more load, which may affect mobility. Alternative treatments or total hip replacement may be better for larger dogs with severe hip issues.

Is FHO surgery painful for dogs?

FHO surgery is performed under general anesthesia, so dogs don’t feel pain during the operation. Post-surgery, pain is managed with medications prescribed by the vet to keep your dog comfortable during healing.

What are the risks of not treating severe hip problems?

Untreated severe hip problems can lead to chronic pain, arthritis, decreased mobility, muscle loss, and a poor quality of life. Over time, the condition worsens, causing more discomfort and difficulty with normal activities.

How does FHO compare to total hip replacement?

FHO removes the femoral head to stop pain, forming a “false joint,” while total hip replacement replaces the entire hip joint with an artificial implant. THR may offer better long-term function but is more complex and costly. FHO is less invasive and often preferred for smaller dogs or when THR isn’t feasible.
