A 9-week-old Thoroughbred x Holsteiner colt was referred for evaluation and treatment of lameness of the right hind limb. Radiography of the stifle revealed multiple bony fragments within the lateral portion of the femorotibial joint and a radiolucency of the distolateral portion of the femur in the area of the extensor fossa, which were consistent with avulsion of the origin of the extensor digitorum longus muscle. Arthroscopy of the lateral portion of the femorotibial joint revealed exposed subchondral bone in the area of the extensor fossa, and the origin of the extensor digitorum longus muscle was determined to be avulsed. The joint was lavaged, and fibrin and fragments of cartilage and bone were removed from the joint. Six months after surgery, the horse appeared normal during trotting and cantering.
一匹9周大的纯种马与荷斯坦奶牛的杂交马驹因右后肢跛行前来接受评估和治疗。膝关节的X线检查显示，股胫关节外侧有多个骨碎片，股骨远端外侧在伸肌窝区域有透亮区，这与趾长伸肌起点撕脱相符。股胫关节外侧的关节镜检查显示伸肌窝区域有裸露的软骨下骨，确定趾长伸肌起点已撕脱。对关节进行了灌洗，清除了关节内的纤维蛋白以及软骨和骨碎片。术后6个月，这匹马在小跑和慢跑时看起来正常。
