OBJECTIVE
To compare the clinical outcomes of minimally invasive total knee arthroplasty (MIS TKA) with and without computer assisted surgery (CAS).
MATERIAL AND METHOD
From September 2007 to February 2008, 64 patients (70 knees) underwent MIS TKA were included. Clinical data such as operative time, pain score, total blood loss and Radiographic data were recorded and compared.
RESULTS
There were no significant different in clinical outcome of both groups but range of motion of MIS group was better than CAS group. However, the percentage of outlier of bone cut in CAS group was 6.5% on both femur and tibia while percentage of outlier in MIS group was 16.6% on femur and 25% on tibia.
DISCUSSION
Combining CAS with MIS TKA showed improvement of accuracy in coronal bone cut without increase of operative time or complications. The difference of ROM may be due to different prosthesis design in each group.
目的
比较有计算机辅助手术（CAS）和无计算机辅助手术的微创全膝关节置换术（MIS TKA）的临床疗效。
材料与方法
纳入2007年9月至2008年2月期间接受MIS TKA的64例患者（70膝）。记录并比较手术时间、疼痛评分、总失血量等临床数据以及影像学数据。
结果
两组临床疗效无显著差异，但MIS组的活动范围优于CAS组。然而，CAS组股骨和胫骨截骨异常值的百分比均为6.5%，而MIS组股骨截骨异常值的百分比为16.6%，胫骨为25%。
讨论
CAS与MIS TKA相结合可提高冠状面截骨的准确性，且不增加手术时间或并发症。活动范围的差异可能是由于每组假体设计不同。
