All 4 felids underwent staged bilateral (snow leopard) or unilateral (cheetahs and tiger [<jats:italic>Panthera tigris<\/jats:italic>]) total hip arthroplasty (THA).<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>TREATMENT AND OUTCOME<\/jats:title>\n<jats:p>In the snow leopard, both femoral THA components were found to be luxated 1 year after surgery. Treatment consisted of autogenous corticocancellous rib graft augmentation of the dorsal acetabular rims and synthetic suture capsulorrhaphies. The snow leopard lived for an additional 4 years with no additional THA-related complications. In the other 3 animals, catastrophic complications (luxation in the cheetahs and femoral fracture in the tiger) occurred shortly after THA. The THA implants were removed, and excision arthroplasty was performed. Long-term outcomes were good in all 3.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Findings underscore the challenges associated with THA in large nondomestic felids. Given the high risk for early catastrophic failure as a result of luxation or fracture, plans must be made and resources must be available in case revision surgery or implant removal with excision arthroplasty becomes necessary.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.21.10.0161","type":"journal-article","created":{"date-parts":[[2021,12,23]],"date-time":"2021-12-23T00:55:08Z","timestamp":1640220908000},"page":"180-187","source":"Crossref","is-referenced-by-count":1,"title":["Complications associated with total hip arthroplasty in four large nondomestic felids"],"prefix":"10.2460","volume":"83","author":[{"given":"Lauren P.","family":"Kane","sequence":"first","affiliation":[{"name":"Chicago Zoological Society, Brookfield Zoo, Brookfield, IL"},{"name":"Illinois Zoological and Aquatic Animal Residency Program, Department of Veterinary Clinical Medicine, College of Veterinary Medicine, University of Illinois, Urbana, IL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James L.","family":"Cook","sequence":"additional","affiliation":[{"name":"Missouri Orthopaedic Institute, University of Missouri, Columbia, MO"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"; Kate E.","family":"Archibald","sequence":"additional","affiliation":[{"name":"Omaha's Henry Doorly Zoo and Aquarium, Omaha, NE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.
