Surface replacement is a conservative treatment for young, active patients with hip osteoarthritis. It provides an increased range of motion as the result of a larger diameter head and improved wear characteristics because of the metal-on-metal articulation as well as an extremely low dislocation rate and increased patient function. While early results are encouraging, long-term outcomes are necessary to define and delineate the role of surface replacement arthroplasty in the treatment of significant hip arthritis.
表面置换术是针对年轻、活跃的髋关节骨关节炎患者的一种保守治疗方法。由于采用了较大直径的股骨头，其活动范围得以增加；金属对金属的关节连接使其具有更好的耐磨特性，同时脱位率极低，患者功能也得到改善。虽然早期结果令人鼓舞，但仍需要长期结果来明确和界定表面置换关节成形术在治疗严重髋关节关节炎中的作用。
