【摘要】：背景:股骨假体旋转不良可造成屈曲间隙不平衡和髌骨轨迹不良,从而影响膝关节功能的恢复。目的:观察全膝关节置换股骨假体旋转角对患者膝关节评分的影响。方法:选取2010年1月至2014年1月在江苏镇江市第一人民医院关节外科行初次全膝关节置换的患者146例(186膝)。置换后进行CT扫描检查并测量股骨髁扭转角评价股骨假体旋转位置,根据股骨髁扭转角分为3组,正常组74例(外旋3°-内旋3°),内旋组15例(内旋3°),外旋组58例(外旋3°),置换后随访3年。结果与结论:①膝关节美国膝关节协会评分:正常组活动功能评分明显高于内旋组和外旋组,外旋组活动功能评分高于内旋组(P0.05);在活动功能评分中3组的标准活动评分、自由活动评分及高级活动评分中,正常组明显高于内旋组和外旋组,外旋组高于内旋组(P0.05);但3组的站立与行走评分、满意度评分和期望评分比较差异无显著性意义;②结果证实:股骨假体旋转角影响全膝关节置换后远期膝关节功能恢复,因此应注意避免置换中股骨假体旋转不良。
[Abstract]:Background: malrotation of femoral prosthesis can result in unbalance of flexion space and poor patellar trajectory, which affects the recovery of knee joint function. Objective: to observe the effect of rotation angle of total knee arthroplasty (TKR) on knee joint score. Methods: from January 2010 to January 2014, 146 patients underwent total knee arthroplasty in the first people's Hospital of Zhenjiang City, Jiangsu Province. The femoral condylar torsion angle was measured by CT scan after replacement to evaluate the rotation position of the femoral prosthesis. According to the femoral condylar torsion angle, the femoral condyle torsion angle was divided into 3 groups. 74 cases in normal group (external rotation 3 掳-internal rotation 3 掳), 15 cases (internal rotation 3 掳) in internal rotation group, 58 cases (3 掳external rotation) in external rotation group, followed up for 3 years after replacement. Results and conclusion: the score of activity function in normal group was significantly higher than that in internal rotation group and external rotation group, and the score of activity function in external rotation group was higher than that in internal rotation group (P 0.05). In the scores of free activity and advanced activity, the normal group was significantly higher than the internal rotation group and the external rotation group, and the external rotation group was higher than the internal rotation group (P 0.05), but there was no significant difference in standing and walking score, satisfaction score and expectation score among the three groups. The results showed that the rotation angle of femoral prosthesis affected the long-term recovery of knee joint function after total knee arthroplasty, so we should avoid malrotation of femoral prosthesis.
