The purpose of this study was to report on the incidence of patellar luxation in 128 dogs out of a total of 317 dogs (40.3%) treated at orthopedic clinics in Chiang Mai, Thailand, from October 2006 through May 2011. Patellar luxation was most frequently found in small breeds, among which Poodles were the most commonly affected (34.3%). Most luxations were medial (89%), and 57.8% of affected dogs were female. Uniluxation of the patella was found in 63%, and biluxation in 37%. Most dogs were classified as patellar luxation grade III. Cranial cruciate ligament rupture was found only in medial patellar luxation grade IV. This study concluded that the incidence of patellar luxation in the local area is high.
