摘　　要：目的探讨后交叉韧带替代型与保留型全膝关节置换术的早期疗效。方法回顾性分析2015年8月至2018年7月期间,因膝骨性关节炎行全膝关节置换术的67例患者。其中35例为后交叉韧带保留型(posterior cruciate-retaining,CR)假体,32例为后交叉韧带替代型(posterior cruciate-substituting,PS)假体。观察比较两组患者的手术时间、术后引流量、住院时间、关节活动度、美国特种外科医院膝关节评分(Hospital for Special Surgery knee score,HSS)。结果PS组患者手术时间(91.77±6.53)min大于CR组(87.48±5.83)min,差异有统计学意义(P<0.05)。PS组术后引流量(315.81±18.34)mL明显大于CR组(203.67±14.59)mL,差异有统计学意义(P<0.05)。在住院时间方面,两组患者间差异无统计学意义(P>0.05)。两组患者术后1、3、6个月的膝关节活动度及HSS差异无统计学意义(P>0.05)。结论CR及PS假体在膝关节置换术后早期均获得良好的效果。在临床中,应根据患者膝关节的情况和术者的个人经验来选择假体。Objective To compare the differences of early clinical efficacy between posterior cruciate-substituting(PS)prosthesis and posterior cruciate-retaining(CR)prosthesis for the patients who underwent total knee arthroplasty(TKA).Methods From August 2015 to July 2018,67 patients who underwent TKA were retrospectively evaluated.There were 32 PS prosthesis and 35 CR prosthesis.The operation time,postoperative drainage blood volume,hospital stay,range of knee joint motion,and Hospital for Special Surgery knee score(HSS)were recorded.Results The operation time in PS and CR groups was(91.77±6.53)min and(87.48±5.83)min,respectively,with statistical significant differences between the two groups(P<0.05).The postoperative drainage blood volume in PS and CR groups was(315.81±18.34)mL and(203.67±14.59)mL,respectively,with statistical significant difference(P<0.05).There were no differences between the two groups of the hospital stay,range of knee joint motion and HSS(P>0.05).Conclusion The early clinical efficacy of both PS and CR prosthesis after TKA was satisfactory.The choice of TKA prosthesis type should be based on patient conditions and surgeon's experiences.
