Abstract: A 2-year-old male Thoroughbred presented with the right hindlimb lameness for the past 3 months. The horse showed swelling around the right stifle. Radiography revealed radiolucency in the medial condyle of the right femur, indicative of subchondral cystic lesion. The horse underwent surgery under general anesthesia. Acortical screw was located on serial radiographs. After placing the screw in the medial condyle, arthroscopy was performed to identify lesions in the femorotibial joint; however, no significant findings were observed. The horse recovered smoothly from anesthesia with assistance and was discharged 1 day later.The owner reported the horse did not show lameness; it returned to training and started racing. This report describes transcondylar screw fixation in a horse with a subchondral bone cyst in South Korea, and suggests that bone screw fixation is an effective treatment for subchondral cystic lesions of the femoral condyle.
