The purpose of this study was to evaluate and compare the quality of life and satisfaction outcomes of patients undergoing primary and revision total knee arthroplasty (TKA). Sixty revision and 199 primary TKA patients were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oxford-12 Knee Score, Short Form-12, and patient-reported satisfaction. Baseline preoperative scores demonstrate that revision TKA patients have inferior quality of life across all measures (WOMAC, Oxford-12, and Short Form-12) in comparison with primary TKA patients (P < .05). At follow-up revision, TKA patients continue to have inferior outcomes (P < .05) in comparison with primary TKA patients. When adjusting for confounding factors in regression analyses, revisions are inferior to primary TKA by 8.6 (95% confidence interval, 2.7-14.6) normalized WOMAC units.
本研究旨在评估和比较初次全膝关节置换术(TKA)和翻修 TKA 患者的生活质量和满意度结果。使用 Western Ontario 和 McMaster 大学骨关节炎指数(WOMAC)、Oxford-12 膝关节评分、Short Form-12 和患者报告的满意度对 60 例翻修和 199 例初次 TKA 患者进行评估。基线术前评分表明,与初次 TKA 患者相比,翻修 TKA 患者在所有指标(WOMAC、Oxford-12 和 Short Form-12)上的生活质量均较差(P<.05)。在随访时,与初次 TKA 患者相比,翻修 TKA 患者的结果仍较差(P<.05)。在回归分析中调整混杂因素后,翻修 TKA 比初次 TKA 差 8.6(95%置信区间,2.7-14.6)个标准化 WOMAC 单位。
