这项研究的目的是在至少15年的随访后，更新一系列初级非骨水泥型全髋关节置换术的结果。这是首批非骨水泥型全髋关节置换术的研究之一，随访至少15年。1983年10月至1986年1月，我们连续植入了100个多孔涂层解剖(PCA)全髋关节置换术。术后至少存活15年的55名患者(64个髋关节)是本研究的重点。在本次随访中，全髋关节置换术后平均15.6年(15~17年)，17%(17个髋关节)和23%(15个髋关节)的活体队列因髋臼假体松动或骨溶解而进行翻修。整个队列中有7%(7个髋关节)和活体队列中有6%(4个髋关节)因股骨假体松动或骨溶解而接受翻修。只有4个股骨柄被修订为孤立的松动(没有骨溶解)。术后至少15年，PCA股骨假体被证明是耐用的，而髋臼假体的耐用性较差。证据水平：治疗性研究，I级(病例系列[无，或既往，对照组])。有关证据级别的完整描述，请参阅对作者的说明。
The purpose of this study was to update the results of a prospective series of primary cementless total hip arthroplasties after a minimum of fifteen years of follow-up. It is one of the first studies of cementless total hip arthroplasties followed for a minimum of fifteen years.One hundred consecutive Porous Coated Anatomic (PCA) total hip replacements were implanted between October 1983 and January 1986. Fifty-five patients (sixty-four hips) that were alive at a minimum of fifteen years postoperatively are the focus of the present study. At this time of follow-up, at an average of 15.6 years (range, fifteen to seventeen years) after the total hip arthroplasty, 17% (seventeen hips) of the entire cohort and 23% (fifteen hips) of the living cohort had undergone revision because of loosening of the acetabular component or osteolysis. Seven percent (seven hips) of the entire cohort and 6% (four hips) of the living cohort had undergone revision for loosening of the femoral component or osteolysis. Only four femoral stems had been revised for isolated loosening (without osteolysis).The PCA femoral component proved to be durable at a minimum of fifteen years postoperatively, while the acetabular component was less durable.Level of Evidence: Therapeutic study, Level I (case series [no, or historical, control group]).
