Although there is general consensus about the efficacy of total hip replacement (THR) in young patients, the most appropriate bearings in young patients remain highly debated. The three most popular bearings in use include metal-on-polyethylene (MOP), metal-on-metal (MOM) and ceramic-on-ceramic (COC). We conducted a systematic review and meta-analysis of literature to summarise the best available evidence on relative success of the three most popular bearings used in THR in young active patients. Our findings support the use of MOM bearings in the management of the young arthritic hip. These findings, largely based upon observational studies, should be taken in the context of the limitations of such non-randomised study designs.
尽管对于年轻患者全髋关节置换术 (THR) 的疗效已经达成普遍共识,但最适合年轻患者的关节仍存在很大争议。目前使用最多的三种关节包括金属对聚乙烯 (MOP)、金属对金属 (MOM) 和陶瓷对陶瓷 (COC)。我们对文献进行了系统回顾和荟萃分析,以总结在年轻活跃患者中使用的三种最流行的关节中,每种关节的相对成功率的最佳现有证据。我们的研究结果支持在年轻关节炎髋关节的管理中使用 MOM 关节。这些发现主要基于观察性研究,应考虑到这种非随机研究设计的局限性。
