Two related female snow leopards (Panthera uncia) were diagnosed with osteochondritis dissecans of the lateral femoral condyle via radiographs and computed tomography. Lesions were either bilateral (Patient 1) or unilateral (Patient 2). Surgical treatment was performed using an osteochondral autograft transfer system following cartilage flap removal. After a 6-wk recovery period, both animals had a markedly improved gait with mild pelvic limb stiffness. Patient 1 developed intermittent lameness 9 mo postsurgery and Patient 2 had mild lameness 3 yr postsurgery. Because of recurrent lameness, both animals were treated with platelet-rich plasma intra-articular injections and oral gabapentin (Patient 1) or oral meloxicam (Patient 2). Full incorporation of autografts was confirmed with computed tomography (both patients) and arthroscopy (Patient 1 only). Osteochondritis dissecans has been previously reported in snow leopards and these cases represent the first reported use of osteochondral autograft repair and platelet-rich plasma to treat the condition.
