Total Hip Replacement (THR) for dogs

Total hip replacement is the most definitive surgical treatment for severe hip dysplasia, end-stage osteoarthritis, or chronic hip luxation in dogs. Unlike palliative procedures, THR restores near-normal joint mechanics by replacing both the femoral head and acetabular socket with prosthetic components.

What it is

The diseased femoral head is removed and replaced with a metal stem and head; the acetabulum is reamed and fitted with a polyethylene cup. Modern systems are available in cemented, cementless, and micro (small-breed) versions. The implant lasts the lifetime of the dog in the great majority of cases.

When it's needed

• Severe hip dysplasia with chronic pain not controlled by medical management
• End-stage hip osteoarthritis affecting quality of life
• Failed femoral head ostectomy (FHO) — though most centers prefer THR before FHO
• Traumatic hip luxation that cannot be stabilized
• Skeletally mature dogs (typically >10–12 months)

The procedure

Performed under general anesthesia by a board-certified surgeon, typically taking 2–3 hours. One hip at a time is operated; the second hip — if also affected — is usually addressed 3–6 months later. Strict aseptic technique is essential due to the implants.

Recovery

8 weeks of strict confinement and controlled leash walks. Bone-implant integration is verified radiographically. Most dogs return to full function by 4–6 months with success rates above 90% in board-certified centers.
