摘　　要：目的探讨膝关节骨性关节炎患者股骨远端旋转解剖标志的变化及其临床意义。方法收集2012年4月—2014年11月因膝关节骨性关节炎拟行全膝关节置换术患者43例的膝关节CT资料,对股骨远端旋转轴线参数进行测量,包括股骨后髁角(PCA)、髁扭转角(CTA)、外科上髁轴线与临床上髁轴线夹角(CSA)。结果不同性别间PCA、CTA比较差异无统计学意义(P>0.05),而女性CSA大于男性(P<0.05)。不同侧别间PCA、CTA、CSA比较差异均无统计学意义(P>0.05)。结论 CT三维重建股骨远端结构有助于膝关节骨性关节炎股骨远端旋转力线的定位,对术中个体化截骨有一定的指导作用。Objective To investigate the variability and clinical significance of distal femoral rotational landmarks of patients with osteoarthritis knees. Methods The CT data of 43 knees undergoing total knee arthroplasty during April 2012 and November 2014 were collected. The rotation axis parameters of distal femur including posterior condylar angle （PCA） , condylar twist angle （CTA） and condylar twist angle （CSA） were detected. Results There were no significant differences in PCA and CTA between males and females （P 〉 0. 05） , and the CSA value of females was higher than that of males （P 〈 0. 05）. There were no significant differences in PCA, CTA and CAS between left and right sides （ P 〉 0. 05）. Conclusion CT 3D-restructured distal femur is helpful in locating the rotation axis parameters of distal fe mur and guiding intraoperative individual osteotomy.
