Plain-English summary
A group of six dogs with severe arthritis in their knee joints underwent total knee replacement surgery to relieve pain and improve mobility. After the surgery, the dogs showed significant improvements in their ability to extend their legs and bear weight within just a few months. By the one-year mark, their overall movement and comfort levels had greatly increased, making total knee replacement a promising option for dogs suffering from severe knee arthritis.

Abstract
OBJECTIVE: To describe a surgical technique for total knee replacement (TKR) in dogs with severe osteoarthritis (OA) and report 1-year outcome. STUDY DESIGN: Prospective clinical case study. ANIMALS: Dogs (n=6) with severe stifle OA. METHODS: Preoperative and postoperative evaluations were compared after 6 dogs had TKR. Data gathered included radiographs, goniometric measures of passive range of motion, ground reaction forces, and girth measurements of the thigh before surgery and at 6 weeks, 3 months, 6 months, and 1 year. RESULTS: Stifle extension and excursion angles were significantly improved by 3 months after TKR. Mean peak vertical force and impulse were significantly improved by 6 months. CONCLUSIONS: TKR is a viable treatment option for dogs with severe stifle OA. CLINICAL RELEVANCE: With continued refinement of surgical technique, instrumentation, and implants, TKR could become a reliable treatment for dogs with disabling, painful nonseptic stifle OA.
