摘要:: 全膝关节置换术(total knee replacement，TKR)术中软组织的不平衡、不稳定与不良的临床结果和术后并发症有关，即使医生在TKR中经过细致的观察，也并未实现完美的软组织平衡。在过去的几十年中，TKR术中的软组织平衡装置发展迅速，已经有机器人辅助下对软组织进行平衡的报道。虽然软组织平衡装置及其技术发展较为成熟，但并非所有接受TKR的患者都能达到手术的最佳结果，或对其手术结果表示高度满意。本研究就近些年来的计算机导航、电子力学测量装置与传统手术器械在TKR中软组织平衡的应用进行综述，并对未来面临的机遇与挑战进行展望。

Abstract:: The imbalance and instability of soft tissue during total knee replacement（TKR）are associated with poor clinical outcomes and postoperative complications. Even after careful observation by the doctor in TKR, the perfect soft tissue balance has not been achieved.In the past few decades, the soft tissue balancing devices in TKR have developed rapidly, and there have been reports on the soft tissue balance with the assistance of robots.Although the soft tissue balancing device and its technology are relatively mature, but not all patients received TKR can achieve the best results of surgery or express high satisfaction with their surgical results.We review the application and progress of TKR soft tissue balance with computer navigation, electronic mechanical measuring devices and traditional surgical instruments in the recent years, and prospectthe opportunities and challenges in the future.
