This narrative review evaluates the purpose and functionality of rotating hinged total knee arthroplasty (RHTKA). The main indications for an RHTKA are poor bone stock, soft tissue compromise, gross instability, and periprosthetic fractures. Studies have shown that an RHTKA may be used in both the primary and revision scenarios to improve the range of motion and functional outcomes. Radiostereometric analysis has shown that some RHTKA designs are associated with early femoral component micromotion, but this has not translated to increased failure or revision rates. Implant survivorship with a modern RHTKA is comparable to a condylar-constrained TKA at mid-term follow-up. The most common complications associated with RHTKA are aseptic loosening, periprosthetic joint infection, stiffness and periprosthetic fractures.
本叙述性综述评估了旋转铰链式全膝关节置换术（RHTKA）的目的和功能。RHTKA的主要适应证为骨量差、软组织受损、严重不稳定和假体周围骨折。研究表明，RHTKA可用于初次和翻修手术，以改善活动范围和功能结局。放射立体测量分析表明，一些RHTKA设计与早期股骨部件微动有关，但这并未转化为更高的失败率或翻修率。在中期随访中，现代RHTKA的植入物生存率与髁限制型全膝关节置换术相当。与RHTKA相关的最常见并发症是无菌性松动、假体周围关节感染、僵硬和假体周围骨折。
