内轴膝关节系统中胫骨假体后倾角度对术后功能影响
组织的阻力,肥胖病人的手术切口并发症及其他手术并发症如深静脉血栓等发病率较其他病人增高,这显然也是影响其术后功能锻炼的重要因素。

多数研究表明,术前ROM与术后ROM呈正相关,认为术前膝关节ROM是预示术后ROM的唯一可信指标,在其他因素相同的情况下,术前膝关节的ROM对TKA术后功能有很大影响,术前ROM大的膝关节比那些术前ROM小的膝关节术后能获得更好的功能[24]。

但也有研究表明,术后的ROM 趋向于一个中间值,认为术前ROM较好的膝关节因为假体设计及手术技巧等诸多因素在术后常常会丧失一些ROM;相反,术前活动相对较差的病人在膝关节置换术后可得到一定程度的改善[22]。

本研究的局限性在于病例数较少,由于X线拍摄等原因可能存在胫骨平台PSA等测量不精确、术中软组织平衡差异等导致的结果不准确;另外,受条件限制仅有MP膝关节置换的病人,并没有对照组,可能存在其他影响膝关节置换术后膝关节ROM的原因,需要今后进一步研究。

综上所述,术前较高的BMI不利于TKA后功能恢复,较好的术前ROM和KSS评分有利于术后膝关节功能的恢复;术后胫骨平台PSA与术后膝关节ROM明显相关,PSA为5°~7°时获得的MP膝关节术后ROM最佳。
