A 37-year-old woman presented with repetitive catching of the right knee 4 weeks after implantation of a 2-plug osteochondral autograft into the medial femoral condyle. The workup indicated that the symptoms were secondary to patellar engagement with the donor sites of the lateral aspect of the trochlea. She subsequently underwent osteochondral allograft implantation, resulting in painless, full range of motion with complete resolution of the mechanical symptoms.
It is important to consider donor-site morbidity following osteochondral autograft implantation, especially in patients with a relatively narrow distal aspect of the femur. Implantation of osteochondral allograft plugs in the symptomatic donor site is a feasible management option for this rarely reported complication.
一名37岁女性在将两枚自体骨软骨移植块植入股骨内侧髁4周后，出现右膝反复卡顿。检查表明，症状是由于髌骨与滑车外侧的供区相接触所致。她随后接受了异体骨软骨移植植入，结果无痛，活动范围完全正常，机械性症状完全消失。
自体骨软骨移植植入后，必须考虑供区并发症，尤其是在股骨远端相对狭窄的患者中。在有症状的供区植入异体骨软骨移植块是这种罕见并发症的一种可行治疗选择。
