When a Dog's Hip Simply Cannot Keep Up
Hip pain affects an estimated 20% of dogs over the age of one, with hip dysplasia alone responsible for a significant proportion of chronic lameness cases in medium to large breeds. For many dogs, the hip joint deteriorates to a point where pain management and physiotherapy can no longer provide a reasonable quality of life. Total hip replacement offers these dogs a genuine return to comfortable movement — not just a reduction in suffering, but the ability to walk, run, and play again.
What Total Hip Replacement Actually Involves
Canine total hip replacement (THR) follows the same fundamental principle as the procedure performed in humans. The surgeon removes the diseased femoral head and neck, then implants an artificial ball component into the femur and a cup component into the acetabulum (the socket of the pelvis). The two components articulate smoothly, replacing the damaged joint surface entirely.
Cemented Versus Cementless Systems
There are two main implant fixation methods. Cemented systems use bone cement to anchor the components immediately, allowing weight-bearing to begin sooner. Cementless systems rely on a porous implant surface that bone grows into over time, providing a more durable long-term bond. Most specialist surgeons now favour cementless implants for younger, active dogs, while cemented options may suit older or smaller patients. Your veterinary orthopaedic surgeon will advise which is appropriate based on your dog's age, size, and bone quality.
The Surgical Process
The operation is performed under general anaesthesia and takes approximately one to two hours per hip. The surgeon accesses the joint, dislocates and removes the femoral head, prepares both the femur and acetabulum to receive implants, and seats the components. Thorough post-operative imaging confirms correct positioning before the dog recovers from anaesthesia.
Which Dogs Are Candidates for Hip Replacement
THR is not appropriate for every dog with hip pain. Ideal candidates typically have severe osteoarthritis or hip dysplasia causing significant lameness that does not respond adequately to conservative management. The dog should be skeletally mature — usually over ten months for smaller breeds and up to eighteen months for giant breeds — so that the bone can support and integrate the implant.
Body weight matters: most implant systems are designed for dogs over fifteen kilograms, though micro-implant systems have expanded access to smaller dogs in recent years. Dogs should be otherwise in good general health, with no active infection, neurological deficits affecting the hindlimbs, or severe muscle wasting that would impair recovery.
Conditions that may exclude a dog from THR include severe hip joint incongruity in very young patients, uncontrolled systemic disease, or orthopaedic problems in multiple limbs that would overwhelm a single-limb surgical intervention. An experienced veterinary orthopaedic specialist will conduct thorough imaging and physical examination before recommending surgery.
What Recovery Looks Like
Recovery from canine THR is substantial and requires a committed owner. The first eight weeks are the most critical, demanding strict exercise restriction to allow soft tissues and bone to heal around the implant.
Weeks One to Four
The dog is confined to a small area — typically a crate or a single room — with only short, controlled lead walks for toileting. Pain management using prescribed analgesics is essential during this period. Most dogs begin bearing some weight on the operated limb within days, which is a positive sign.
Weeks Four to Eight
Controlled lead walks are gradually extended, and physiotherapy or hydrotherapy typically begins under veterinary guidance. These sessions help rebuild muscle mass, improve range of motion, and re-educate the dog's gait without placing undue stress on the new joint.
Beyond Eight Weeks
Follow-up radiographs assess implant integration. If healing is progressing well, activity is cautiously increased over the following weeks. Most dogs reach full activity by four to six months post-surgery, with many owners reporting that their dog moves better than it has in years.
Risks and Complications
As with any major surgery, THR carries risks. Dislocation of the implant in the early post-operative period is the most common complication, often linked to excessive activity before healing is complete. Infection, implant loosening, fracture around the implant, and nerve damage are less frequent but recognised possibilities. Complication rates are significantly lower when surgery is performed by a board-certified veterinary orthopaedic surgeon at a specialist centre with experience in THR procedures.
In cases where complications are severe, revision surgery or conversion to a femoral head and neck excision (see a separate article on this site) may be required.
Cost, Access, and Alternatives
Total hip replacement is one of the most expensive orthopaedic procedures in veterinary medicine, with costs per hip typically ranging from several thousand pounds at specialist referral centres in the UK. Pet insurance that covers orthopaedic conditions may offset a significant portion of this cost, and it is worth reviewing your policy carefully before a referral is made.
For dogs who are not suitable candidates or whose owners cannot access THR, alternatives include femoral head and neck excision, long-term pain management with non-steroidal anti-inflammatory drugs, joint supplements, physiotherapy, and hydrotherapy. None of these replaces the function that a successful THR achieves, but they can meaningfully improve quality of life.
Key Takeaways
- Total hip replacement removes the diseased joint and replaces it with artificial components, offering the most complete resolution of hip pain.
- Ideal candidates are skeletally mature dogs with severe hip disease who have not responded to conservative treatment.
- Recovery requires eight or more weeks of strict exercise restriction followed by graduated physiotherapy.
- Complication rates are lower at specialist centres with dedicated orthopaedic surgeons.
- Always discuss the full range of surgical and non-surgical options with a veterinary orthopaedic specialist before making a decision.
