The purpose of this study was to evaluate patient factors that might contribute to a poor result after total knee arthroplasty (TKA). Seventy-one knees (6.9%) of 1024 primary TKAs were identified at 1 year follow-up as having a poor result because of either stiffness or pain. Radiographs demonstrated well-fixed and aligned implants. This group was compared with a matched control group of 148 nonpainful or stiff TKAs, with similar range of motion preoperatively. Logistic regression analysis was performed to compare age, sex, body mass index, comorbidities, previous surgeries, preoperative narcotic use, tobacco or alcohol use, work status, insurance status, and any history of depression. Factors that were significantly associated with a stiff or painful outcome included female sex, higher body mass index, previous knee surgery, patients on disability, diabetes mellitus, pulmonary disease, and depression.
本研究的目的是评估可能导致全膝关节置换术（TKA）后效果不佳的患者因素。在1年随访时，1024例初次TKA中有71例膝关节（6.9%）因僵硬或疼痛而效果不佳。X线片显示植入物固定良好且排列整齐。将该组与148例无疼痛或僵硬的TKA匹配对照组进行比较，两组术前活动范围相似。进行逻辑回归分析以比较年龄、性别、体重指数、合并症、既往手术史、术前使用麻醉剂情况、吸烟或饮酒情况、工作状态、保险状态以及任何抑郁病史。与僵硬或疼痛结局显著相关的因素包括女性、较高的体重指数、既往膝关节手术史、残疾患者、糖尿病、肺部疾病和抑郁症。
