Eight patients were seen with idiopathic chondrolysis in nine hips, with from one to eight years' follow-up. The adolescent patients showed characteristic diagnostic patterns--patients in the hip and a limp. The disease occurs most frequently in black girls and in them it tends to be more severe. Threre is progressive loss of articular cartilage, frequently progressing to flexion-adduction contracture and fibrous ankylosis. The pathological process in our patients mainly consisted of chronic synovitis and loss of articular cartilate in the weight-bearing surface of the femoral head. The patients with mild cases were satisfactorily treated with physical therapy, non-weight-bearing, and analgesics. The other hips, however, did best when allowed to undergo fibrous ankylosis with the hip in a functional position.
8例患者共9个髋关节出现特发性软骨溶解，随访1至8年。青少年患者呈现出特征性的诊断模式——髋关节病变及跛行。该疾病在黑人女孩中最为常见，且病情往往更严重。关节软骨逐渐丧失，常发展为屈曲内收挛缩和纤维性强直。我们患者的病理过程主要包括慢性滑膜炎以及股骨头负重面关节软骨的丧失。轻症患者通过物理治疗、不负重及使用镇痛药得到了满意的治疗效果。然而，其他髋关节在髋关节处于功能位时允许其发生纤维性强直的情况下效果最佳。
