后交叉韧带保留型及替代型假体在全膝关节置换术后早期疗效比较

Early efficacy of posterior cruciate retaining prosthesis versus substituting prosthesis in total knee arthroplasty

目的比较后交叉韧带保留型(CR)及替代型(假体在全膝关节置换术后早期疗效。方法 PR)因晚期膝关节病变而行全膝关节置换术患者69例(72膝),其中38例(40膝)使用CR假体治疗,31例(32膝)使用PS假体治疗。比较两组手术时间、术中出血量、术后引流量、评分、膝关节活动度。结果 HSS两组手术时间、术中出血量、术后引流量、以及术后2周、3个月、12个月HSS评分和膝关节活动度差异无统计学意义(P。结论 >0.05)两种假体在全膝关节置换术后早期均获得良好疗效。

Objective To compare the early efficacy of posterior cruciate retaining （CR） and posterior cruciate substituting （PS） prosthesis in total knee arthroplasty （TKA）. Methods Sixty-nine patients with advanced knee ostearthritis （72 knees） underwent TKA with CR （n=38, 40 knees） or PS （n=31, 32 knees）. Operation time, intraoperative blood loss, postoperative drainage, and American Hospital for Special Surgery （HSS） knee scores and knee joint activity after operation were compared between 2 groups. Results Operation time, intraoperative blood loss, postoperative drainage, and HSS knee scores and knee joint activity 2 weeks, 3 months and 12 months after operation showed no significant difference between 2 groups （P〉0.05）. Conclusion The two kinds of prostheses provide good early efficacy in TKA.
