Abstract

The purpose of this study is to identify clinical features of sound (non-lame) dogs with medial patellar luxation (MPL). Medical records of 72 dogs diagnosed with MPL were retrospectively reviewed. There were no significances in breed, sex, body weight, body condition score (BCS), osteoarthritis (OA) score, inclination of the femoral head angle (IFA), and mechanical medial proximal tibial angle (mMPTA) between sound and lame dogs, respectively. The mean age of sound dogs was significantly higher than that of lame dogs (P < 0.05), especially in MPL grade 3. The frequency of sound dogs with MPL grade 1 and 2 was 2.3 times higher than that of sound dogs with MPL grade 3 and 4 (P < 0.05). The anatomical lateral distal femoral angle (aLDFA) of sound dogs was significantly lower than that of lame dogs (P < 0.05). However, there were no statistical differences in aLDFA between sound and lame dogs in MPL grade 1, 2, and 4, except for MPL grade 3. This study suggests that in case of MPL grade 1 and 2, frequency of sound dogs is significantly high, and also that in MPL grade 3, if mean ± (standard deviation) age of the dogs is 7.4 ± 3.6 years old and the aLDFA is 105.6 ± 4.1 degrees, they are very highly possible to be sound dogs.
