Osteochondritis dissecans lesions on the medial trochlear ridge of the femur in three bulldog‐type dogs

Abstract Four osteochondritis dissecans (OCD) lesions were identified on the medial femoral trochlear ridge in three bulldog‐type dogs, all of which concurrently presented with varying grades of medial patellar luxation in the affected limbs. Diagnosis of these lesions was made using computed tomography and confirmed at surgery in all cases. This case series adds to the existing literature by identifying the medial femoral trochlear ridge as a site of OCD pathology in bulldog‐type breeds and highlighting medial patellar luxation as a frequently encountered comorbidity. To the authors’ knowledge, this is the first report of OCD lesions in this location identified in non‐related bulldogs.
