FHO Recovery
This page is for educational purposes only and is not a substitute for veterinary diagnosis or emergency care. Always consult your primary veterinarian or a rehabilitation veterinarian before starting treatment. If your pet cannot walk, has sudden paralysis, severe pain, or breathing difficulty, seek urgent veterinary attention.
What is FHO Recovery?
Also known as: femoral head and neck ostectomy recovery; femoral head ostectomy rehab; excision arthroplasty recovery.
FHO is a salvage procedure for painful hip disease when joint preservation or total hip replacement is not chosen — including severe osteoarthritis, fractures of the femoral head/neck, Legg-Calvé-Perthes disease, and some luxations. After removal of the femoral head and neck, a fibrous false joint (pseudoarthrosis) develops; muscular support becomes the primary stabiliser.
Unlike many orthopaedic surgeries that emphasise prolonged unloading, FHO outcomes depend heavily on early, guided use of the limb and aggressive (but comfortable) rehabilitation to prevent restrictive scar and build gluteal and thigh strength. Cats often do well functionally; small dogs are classic candidates, though larger dogs may also undergo FHO with realistic expectation setting.
Rehab programmes emphasise early passive and active motion, weight-shifting, sit-to-stands, underwater treadmill when cleared, and owner-led daily exercises. Pain control from the veterinary team enables participation.
Common signs to watch for
Signs vary by severity and by whether your pet is a dog or cat. Owners of dogs and cats often notice:
- Recent FHO for hip pain, fracture, or Perthes disease
- Hesitancy to use the operated hind limb in the first post-op period
- Rapid muscle loss around the hip and thigh if the limb is not used
- Shortened stride or hip hiking during gait
- Difficulty with stairs or jumping during recovery
- Need for structured daily exercises beyond crate rest alone
Causes & contributing factors
- Surgical removal of the femoral head/neck changing hip mechanics
- Post-operative pain limiting voluntary limb use
- Scar tissue formation if motion is inadequate
- Pre-existing disuse atrophy from chronic hip pain
- Inadequate home exercise compliance delaying strength return
How veterinary rehabilitation helps
Early guided physiotherapy encourages limb use that shapes a mobile pseudoarthrosis and reduces adhesions. Therapists teach owners high-frequency short exercise bouts.
Progressive strengthening targets gluteals, quadriceps, and core. Hydrotherapy helps reluctant users begin weight-bearing with support.
Longer-term conditioning restores endurance for walks and play; expectations for athletic performance are discussed honestly for larger dogs.
Rehabilitation plans at RehabVet are individualised after a veterinary assessment. We coordinate with your primary vet when imaging, medication, or surgery is part of the overall plan.
Modalities & services commonly used at RehabVet
Depending on your pet’s examination findings, comfort, and goals, a plan may include one or more of the following:
Expected rehabilitation goals
Goals are set for the individual patient. Typical aims may include (not guarantees — outcomes vary):
- Encourage early comfortable weight-bearing on the operated limb
- Maximise hip-region mobility and minimise restrictive scar
- Rebuild pelvic-limb muscle mass and endurance
- Normalise gait as much as individual anatomy allows
- Empower owners with a reliable daily home programme
We do not publish invented success percentages. Progress is tracked clinically (gait, strength, range of motion, pain behaviours, and home function) and plans are adjusted over time.
When to seek veterinary care
- Incision complications or sudden refusal to use the limb after progress
- Severe pain not controlled by prescribed medication
- Ideally start rehab planning before or immediately after FHO
- If the limb remains unused despite pain control — prompt rehab review
- Why is physiotherapy so important after FHO compared with some other surgeries?
FHO relies on soft-tissue support and a mobile false joint. Early motion and muscle building strongly influence comfort and function; passive crate rest alone is usually insufficient.
- Can large dogs do well after FHO?
Some do functionally for pet lifestyles; others have more mechanical limitations than with total hip replacement. Your surgeon discusses candidacy; rehab maximises whatever procedure is chosen.
- Are cats good FHO candidates?
Many cats recover functional mobility after FHO with appropriate pain control and rehab-focused encouragement to use the limb and jump within guided limits.
