2011年膝关节学会膝关节评分系统（KSS）是一种新的患者衍生结局指标，旨在更好地表征全膝关节置换术后的满意度、期望值和体力活动。在75例患者（92个膝关节）中，通过计算机断层扫描评估股骨和胫骨部件的旋转对线，并评估其对KSS评分的影响。股骨部件相对于手术上髁轴的内旋显著降低了功能活动评分，并略微降低了满意度评分。股骨部件旋转不良不影响症状和预期评分。胫骨部件旋转不良不影响2011年KSS的任何评分。外科医生应避免股骨部件内旋，以保持功能活动。(C)2014 Elsevier Inc. All rights reserved.
The 2011 Knee Society Knee Scoring System (KSS) was developed as a new patient-derived outcome measure to better characterize satisfaction, expectations, and physical activities after total knee arthroplasty. The rotational alignment of the femoral and tibial components was assessed with computed tomography in 75 patients (92 knees), and its effect on the scores of the KSS was evaluated. Internal rotation of the femoral component relative to the surgical epicondylar axis significantly decreased the score of functional activities and slightly decreased the score of satisfaction. Femoral component malrotation did not affect the scores of symptoms and expectations. Tibial component malrotation did not affect any of the scores of the 2011 KSS. Surgeons should avoid internal rotation of the femoral component to preserve functional activities. (C) 2014 Elsevier Inc. All rights reserved.
