The aim of this study was to evaluate the relationship between clinical results including patient-reported outcomes and intraoperative knee kinematic patterns after total knee arthroplasty (TKA). A cross-sectional survey of forty consecutive medial osteoarthritis patients who had a primary TKA using a CT-based navigation system was conducted. Subjects were divided into two groups based on intraoperative kinematic patterns: a medial pivot group (n = 20) and a non-medial pivot group (n = 20). Subjective outcomes with the new Knee Society Score and clinical outcomes were evaluated. The functional activities, patient satisfaction and the knee flexion angle of the medial pivot group were significantly better than those of the non-medial pivot group. An intraoperative medial pivot pattern positively influences deep knee flexion and patient-reported outcomes.
本研究旨在评估全膝关节置换术（TKA）后临床结果（包括患者报告的结果）与术中膝关节运动学模式之间的关系。采用基于 CT 的导航系统对 40 例初次 TKA 的内侧骨关节炎患者进行了横断面调查。根据术中运动学模式将受试者分为两组：内侧旋转组（n = 20）和非内侧旋转组（n = 20）。评估了新膝关节学会评分的主观结果和临床结果。内侧旋转组的功能活动、患者满意度和膝关节屈曲角度明显优于非内侧旋转组。术中内侧旋转模式对深度膝关节屈曲和患者报告的结果有积极影响。
