Total hip replacement restores mobility in dog with hip dysplasia
Bottom line
A young golden retriever-poodle mix with progressive hip dysplasia and eventual left hip luxation regained comfort and mobility after total hip replacement at the UC Davis William R. Pritchard Veterinary Medical Teaching Hospital. According to UC Davis’s April 27, 2026 case report, the dog, Andy, was first diagnosed as a puppy, managed conservatively for several years, then underwent CT-based surgical planning in July 2025 and total hip replacement in September 2025 after pain and lameness worsened despite medical management. The procedure replaced both the femoral head and acetabulum with metal and polyethylene implants, followed by six days of hospitalization and strict activity restriction during recovery.

Why it matters: For veterinary professionals, the case is a straightforward reminder of where total hip replacement fits in the treatment pathway for severe canine hip dysplasia: not as first-line care for every patient, but as a strong option when pain, osteoarthritis, instability, or luxation progress despite weight control, rehabilitation, supplements, and analgesia. ACVS notes that total hip replacement can restore more normal joint function than salvage options like femoral head ostectomy, particularly in appropriately selected dogs that are mature enough for surgery, while other sources emphasize that earlier diagnosis can open the door to joint-preserving procedures before osteoarthritis advances.

What to watch: Expect continued attention on case selection, implant choice, and complication management as more centers publish canine total hip replacement outcomes and refine preoperative planning. (northstarvets.com)
A UC Davis case report is putting a familiar orthopedic principle into sharp focus: for some dogs with severe hip dysplasia, total hip replacement can meaningfully restore function and quality of life when conservative care is no longer enough. In the case, published April 27, 2026, a young goldendoodle named Andy underwent total hip replacement after progressive disease led to worsening pain, lameness, osteoarthritis, and left hip luxation. UC Davis reports that he is now fully recovered and able to run comfortably after surgery and rehabilitation. (vetmed.ucdavis.edu)
The background is clinically recognizable. Hip dysplasia is a developmental, multifactorial disease driven in large part by inherited risk, with joint laxity leading over time to osteoarthritis, pain, and limb dysfunction. UC Davis and the American College of Veterinary Surgeons both note that signs can emerge early or later depending on severity and contributing factors such as body condition, while early screening can identify some patients in time for joint-preserving procedures like juvenile pubic symphysiodesis or triple pelvic osteotomy. Once arthritis is established, though, the conversation often shifts toward long-term medical management or salvage surgery. (healthtopics.vetmed.ucdavis.edu)
In Andy’s case, that progression played out over several years. UC Davis said he was diagnosed in 2021 after his primary veterinarian took radiographs, then managed with monitoring before pain-control medications became less effective. By June 2025, referral imaging at UC Davis showed moderate arthritis and severe left hip dysplasia with luxation. After discussing options, including continued management, femoral head ostotomy, and total hip replacement, the care team and pet parents moved forward with THR. A CT scan was used in July 2025 for surgical planning, and the September 2025 procedure used a biologic THR system with titanium, cobalt-chromium, and polyethylene components sized to the patient’s anatomy. Postoperative radiographs showed appropriate implant positioning, and the dog was discharged after six days with strict confinement and leash-only activity until recheck. (vetmed.ucdavis.edu)
The broader literature supports why the UC Davis team framed THR as the best long-lasting option in this setting. ACVS describes total hip replacement as a procedure that reproduces the mechanics of a more normal hip joint and can provide the most normal pain-free function for dogs with hip dysplasia that are old enough for surgery. Merck Veterinary Manual similarly lists THR as the surgical option for optimal restoration of joint and limb function in severe cases, while Cornell notes it is used more commonly in larger dogs when medical management is inadequate.

At the same time, the procedure is not simple, and that nuance matters. Published outcome data on canine hip arthroplasty generally support strong success rates, but complications remain a real part of the conversation. In one recent JAVMA report evaluating a cementless THA system in 17 dogs, authors described THA as the gold standard with reported success rates above 95% in prior literature, but also noted known complications across systems, including infection, implant loosening, luxation, fracture, and nerve injury. In that series, 25% of hips had postoperative complications, underscoring that surgical expertise, implant familiarity, and follow-up are central to outcomes. (northstarvets.com)
Why it matters: For general practitioners and specialists alike, this case is less about novelty than about decision timing. It highlights the value of early recognition, weight management, multimodal pain control, and referral before function deteriorates too far, while also showing that dogs with advanced disease can still do very well with definitive surgical treatment. It’s also a useful client-communication example: UC Davis documented a stepwise process that included conservative care, candid discussion of FHO versus THR, CT-based planning, hospitalization, and a tightly controlled recovery period. That’s the kind of pathway pet parents need to understand clearly before they commit to a high-cost, high-skill orthopedic intervention. (vetmed.ucdavis.edu)
For referral centers, the case also reflects how canine THR continues to mature as a subspecialty service. UC Davis highlights dedicated joint replacement expertise and even custom implant capabilities within its surgery program, while recent research from UC Davis-affiliated investigators is examining technical variables such as cup inclination and impingement-free motion after canine THR. That suggests the next phase of progress may be less about proving the concept and more about improving planning, implant positioning, training, and complication avoidance. (vetmed.ucdavis.edu)
What to watch: Watch for more outcomes data from academic and specialty centers on implant-specific performance, complication rates, and which patients benefit most from THR versus FHO or earlier joint-preserving surgery, especially as advanced imaging and procedure-specific training become more common.
