Radiographs of stifle joints were evaluated for signs of osteoarthritis. Long-term function was classified as poor, fair, good, or excellent.\n <\/jats:p>\n \n Results<\/jats:bold>\n \u201434 cats had bilateral luxation and 8 had unilateral luxation. Only 7 (17%) cats had a history of trauma. Mean age of the cats was 3.3 years, and mean weight was 4.26 kg (9.4 lb); 26 (62%) were domestic shorthairs. Seventy-three of the 76 (95%) affected joints had medial patellar luxation. Luxation grades could be assigned to 65 joints, with grade 2 (30 joints) and 3 (22 joints) luxation being most common. Lameness grades could be assigned to 73 joints, with grade 1 lameness (27 joints) most common. Outcome was excellent for 8 of 17 joints treated without surgery and for 23 of 35 joints treated surgically. Complications attributable to surgery were reported in 8 cats.\n <\/jats:p>\n \n Conclusions and Clinical Relevance<\/jats:bold>\n \u2014Patellar luxation should be considered as a cause of hind limb lameness in cats. Low-grade luxation can be associated with lameness of the same severity as high-grade luxation. Surgical correction of patellar luxation in cats with grade 2 or 3 lameness can result in a favorable outcome.\n <\/jats:p>","DOI":"10.2460\/javma.228.9.1370","type":"journal-article","created":{"date-parts":[[2006,5,1]],"date-time":"2006-05-01T12:35:03Z","timestamp":1146486903000},"page":"1370-1375","source":"Crossref","is-referenced-by-count":49,"title":["Clinical signs and results of treatment in cats with patellar luxation: 42 cases (1992\u20132002)"],"prefix":"10.2460","volume":"228","author":[{"given":"Catherine A.","family":"Loughin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon C.","family":"Kerwin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giselle","family":"Hosgood","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.
