Note the joint capsule swelling and irregular contour of the trochlear ridge. There is some disagreement regarding appropriate treatment of Osteochondritis dissecans of the hock. In our experience, however, non-surgical management is frequently unrewarding and does not address the cause of the arthritic degeneration. Large non-degenerate fragments have been successfully stabilized. Advocates of this approach cite maintenance of joint stability as the primary advantage, but adequate exposure may require an aggressive surgical approach via malleolar osteotomy, and the percentage of viable candidates for this approach is low.
Most surgeons advocate removal of osteochondral fragments and curettage of the lesion's bed.
Use of these approaches require specific identification of the lesions prior to surgery and are associated with minimal morbidity. Fragment excision probably does not significantly reduce hock stability and removal of the loose articular cartilage eliminates a source of intra-articular inflammation. A soft padded bandage is applied for 3-5 days following surgery and the dog is restricted to kennel confinement and leash exercise for 2 to 3 weeks. Dorsomedial approach to the hock. Plantaromedial approach to the hock.
