This study is a systematic literature review of outcomes following total knee arthroplasty with implants specifically designed to enable increased knee flexion. English language comparative studies without date restriction were identified through a computerised literature search and bibliography review. Nine studies met the inclusion criteria representing a total of 399 high-flexion knee arthroplasties in 370 patients. Five studies reported greater flexion or range of motion; however, the methodological rigour was questionable with inadequate blinding, flawed participant selection, short follow-up periods and functional outcomes which lacked sensitivity. There was insufficient evidence of improved range of motion or functional performance after high-flexion knee arthroplasty.
本研究是一项系统性文献综述,聚焦于使用专门设计以增加膝关节屈曲度的植入物进行全膝关节置换术后的结果。通过计算机文献检索和参考文献回顾,确定了无日期限制的英文比较研究。九项研究符合纳入标准,共涉及370例患者的399例高屈曲度膝关节置换术。五项研究报告了更大的屈曲度或活动范围;然而,其方法学严谨性存疑,存在盲法不足、参与者选择有缺陷、随访期短以及功能结果缺乏敏感性等问题。没有足够证据表明高屈曲度膝关节置换术后活动范围或功能表现得到改善。
