Plain-English summary
A group of dogs with osteochondrosis (a joint condition) affecting either the medial or lateral trochlear ridge of the ankle joint was studied to compare their symptoms and the size of the bone lesions. The dogs with lateral trochlear ridge osteochondrosis had larger lesions and were diagnosed at a younger age compared to those with medial trochlear ridge osteochondrosis. This suggests that dogs with lateral lesions may show signs of limping or discomfort sooner. Understanding these differences can help veterinarians provide better treatment options for affected dogs.

Abstract
OBJECTIVE: To evaluate clinical and subchondral bone lesion differences between medial (MTRT-OC) and lateral trochlear ridge tarsocrural osteochondrosis (LTRT-OC). STUDY DESIGN: Retrospective case series. ANIMALS: Dogs (n = 66) with MTRT-OC or LTRT-OC. METHODS: Medical records (1997-2010) of dogs with MTRT-OC or LTRT-OC were reviewed. Clinical data (breed, age, gender, weight, and duration of clinical signs) were retrieved. Computed tomographic examinations of the tarsocrural joints were performed. Length, width, and depth of the subchondral bone lesions on the computed tomographic images, and surface and volume of the lesions were estimated. The location of the OC lesion on the trochlear ridge (proximal, dorsal, or distal) was determined. Data collected from dogs with MTRT-OC (n = 56) were compared with data from dogs with LTRT-OC (n = 10). RESULTS: Length, width, depth, surface, and volume of LTRT-OC lesions were significantly (P < .01) larger than those of MTRT-OC lesions. Dogs with LTRT-OC were significantly younger at the time of diagnosis (P < .01). CONCLUSIONS: OC lesions on the lateral trochlear ridge are significantly larger than those on the medial trochlear ridge. Dogs with lesions on the lateral trochlear ridge are significantly younger at the time of diagnosis, and tend to have a shorter duration of lameness before presentation.
