Despite the success of total knee arthroplasty (TKA), numerous studies report that nearly one in five patients who underwent TKA was unsatisfied with their outcome. The purpose of our study was to identify the preoperative factors predictive of satisfaction following well-performed TKA. Using improvement in patient-reported outcomes less than the minimally clinically important change as an indicator of dissatisfaction in a cohort of primary TKA patients, we found that patients with greater preoperative pain and disability with less severe degradation in health-related quality of life were more likely to be satisfied with the result of TKA. Balancing severity of symptoms and impact to quality of life is important when counseling patients considering TKA.
尽管全膝关节置换术（TKA）取得了成功，但众多研究报告称，接受TKA的患者中近五分之一对其手术结果不满意。我们研究的目的是确定在成功实施TKA后预测满意度的术前因素。在一组初次TKA患者中，将患者报告结局的改善低于最小临床重要变化作为不满意的指标，我们发现术前疼痛和残疾程度较高、健康相关生活质量下降不太严重的患者更可能对TKA结果感到满意。在为考虑进行TKA的患者提供咨询时，平衡症状的严重程度和对生活质量的影响非常重要。
