The long-term results of 49 Charnley low-friction arthroplasties performed in patients 30 years of age or younger at the time of surgery was reviewed, with special emphasis placed on the radiologic evaluation of the acetabular and femoral components with average follow-up period of nearly ten years and the longest follow-up period of 15.5 years. Fifty-three percent of the sockets had no cement-bone demarcation and 28.6% had only a small line in the upper outer quadrant of the socket. Of the seven sockets that failed (14.3%), six had very deficient bone stock at operation. There were only two cases of femoral loosening. The rate of wear was 1.7 mm at ten years, which is not much greater than in older patients. Most of these cases were patients with conditions causing built-in restraints against over activity.
回顾了49例接受Charnley低摩擦人工关节置换术的患者的长期结果，这些患者手术时年龄在30岁及以下，特别强调对髋臼和股骨组件进行放射学评估，平均随访期近十年，最长随访期为15.5年。53%的髋臼杯没有骨水泥-骨分界，28.6%的髋臼杯仅在髋臼杯上外象限有一条小线。在7个失败的髋臼杯（14.3%）中，6个在手术时骨量非常不足。只有2例股骨松动。十年时磨损率为1.7毫米，这与老年患者相比增加不多。这些病例大多数是患有对过度活动有内在限制的疾病的患者。
