To identify factors associated with functional recovery and outcome 1 year after total knee arthroplasty (TKA).
In the prospective follow-up study, all the patients (n = 75, aged 60-80 years) underwent primary TKA. Assessments were performed preoperatively and 12 months after surgery. The main measures were the Western Ontario and McMaster Universities OA Index (WOMAC) and the 15D. The clinical examination included analyses of comorbidity and a detailed knee examination. Age-standardised population values of the 15D and the Outcome Measures in Rheumatology-Osteoarthritis Research Society International (OMERACT-OARSI) criteria were used as indices of response.
Osteoporosis, pain, gender, age and preoperative function of the opposite knee accounted for 29.9% of the variance in the change in the WOMAC function score. A preoperative score of the 15D below the age-standardised population level, pain, higher age and pulmonary disease reduced the possibility to reach the HRQOL level of the general population. Osteoporosis decreased the likelihood of achieving responder status according to the OMERACT-OARSI criteria.
The baseline preoperative score of the 15D strongly associated with the achieved level of HRQOL after TKA. The findings of the present study highlight the multifactorial nature of health status in TKA.
确定与全膝关节置换术（TKA）后功能恢复和 1 年结局相关的因素。
在这项前瞻性随访研究中，所有患者（年龄 60-80 岁，n=75）均接受初次 TKA。术前和术后 12 个月进行评估。主要测量指标为西部安大略省和麦克马斯特大学骨关节炎指数（WOMAC）和 15D。临床检查包括合并症分析和详细的膝关节检查。15D 的年龄标准化人群值和骨关节炎疗效评价协会国际（OMERACT-OARSI）标准被用作反应的指标。
骨质疏松症、疼痛、性别、年龄和对侧膝关节术前功能占 WOMAC 功能评分变化的 29.9%。术前 15D 评分低于年龄标准化人群水平、疼痛、年龄较大和肺部疾病降低了达到一般人群健康相关生活质量水平的可能性。骨质疏松症降低了根据 OMERACT-OARSI 标准达到反应者状态的可能性。
15D 的基线术前评分与 TKA 后获得的 HRQOL 水平密切相关。本研究的结果强调了 TKA 中健康状况的多因素性质。
