Plain-English summary
A group of nine dogs with hind leg limping were found to have a condition called medial trochlear ridge talar osteochondritis dissecans (MTRT-OCD), which involves bone lesions in the ankle joint. The dogs showed lameness on one side, while the other side had similar lesions but no visible limping. Tests revealed that the lesions causing lameness were larger and linked to more joint damage. This suggests that bigger lesions are likely to cause more noticeable symptoms. Treatment details were not provided, but understanding the size of these lesions can help vets manage the condition better.

Abstract
In this retrospective study of nine dogs exhibiting bilateral medial trochlear ridge talar osteochondritis dissecans (MTRT-OCD) and unilateral hind limb lameness, we compared subchondral lesion size in limbs with visible lameness, with contralateral lesions that were not associated with any visible lameness. All MTRT-OCD lesions were imaged by radiography and computed tomography (CT). The dimensions of subchondral bone lesions were measured (length, width and depth) using CT software. Similar to a method used in humans, the estimated volume (length x width x depth) and cross sectional area (length x width) were calculated and compared. We found that MTRT-OCD lesions causing visible lameness were significantly larger, and were associated with more joint thickening and degenerative joint disease than contralateral lesions that were not associated with any apparent lameness. As in the disease of shoulder osteochondritis dissecans, there is probably a correlation between the size of MTRT-OCD lesions and the symptoms of lameness.
