To date, the vast majority of resurfacing failures have been caused by either femoral-sided aseptic loosening or femoral neck fracture. 迄今为止，大多数表面置换的失败都是因为股骨侧的无菌性松动或者股骨颈骨折。
Aseptic loosening of prosthesis resulting from periprosthetical osteolysis after artificial joint replacement is the main cause affecting its in-service life. 人工关节置换术后假体周围骨溶解所引起的假体无菌性松动是影响其使用寿命的主要原因之一。
