背景运动学对齐（KA）全膝关节置换术（TKA）有望提高患者满意度，但其效果仍存在争议。我们使用再现解剖几何形状的植入物研究了 KA 和非 KA TKA 之间患者报告结果 (PRO) 的差异。方法通过使用传统器械的测量切除技术，对连续 129 名患者（149 个膝盖）进行了内翻畸形 TKA。术后（平均13.6个月）测量股胫角（FTA）、髋膝踝角（HKAA）以及关节线与机械轴垂直线之间的夹角（AJLMA），AJLMA为2°定义为运动学对准。在每种测量方法中，患者被分配到两个或三个体位类别，并对各组之间的膝关节协会评分 (KSS) 和日本膝关节损伤和骨关节炎结果评分 (J-KOOS) 进行比较。结果对于通过 FTA 评估的患者，ADL 相关 J-KOOS 子量表 (J-KOOS-A) 显示外翻和内翻异常值之间存在显着差异 (p
BackgroundA kinematically aligned (KA) total knee arthroplasty (TKA) is expected to improve patient satisfaction, but its effect remains controversial. We investigated differences in patient-reported outcomes (PROs) between KA and non-KA TKAs using an implant that reproduces anatomical geometry.MethodsTKAs for varus deformity were performed in consecutive 129 patients (149 knees) via a measured resection technique with conventional instruments. The femorotibial angle (FTA), hip-knee-ankle angle (HKAA), and the angle between the joint line and the line perpendicular to the mechanical axis (AJLMA) were measured postoperatively (mean 13.6months), and an AJLMA of 2 degrees was defined as kinematic alignment. Patients were assigned to two or three alignment categories in each measurement method, and the Knee Society Scores (KSS) and Japanese Knee Injury and Osteoarthritis Outcome Scores (J-KOOS) was compared among the groups.ResultsFor patients assessed by FTA, an ADL-related J-KOOS subscale (J-KOOS-A) showed a significant difference between valgus and varus outliers (p
