Six patients with osteonecrosis of the medial femoral condyle were seen during a 3 1/2-year period in a rheumatology unit. This condition, which may not be rare, is characterized by the sudden onset of pain in the knee of elderly people (usually women) without significant trauma. Physical signs include effusion and tenderness at the medial margin of the knee joint. Radiographic changes may not be evident for weeks or even months. The later appearances are characteristic and the site of the lesion is remarkably constant.
在一个风湿科单位的3年半时间里，共诊治了6例股骨内侧髁骨坏死患者。这种情况可能并不罕见，其特点是老年人（通常为女性）在无明显外伤的情况下突然出现膝关节疼痛。体征包括膝关节内侧缘积液和压痛。数周甚至数月内，影像学改变可能不明显。后期表现具有特征性，且病变部位非常恒定。
