This study compared outcomes as assessed by 12-item Short-Form Health Survey (SF-12) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) between patients who underwent unicompartmental (UKA) and patients who underwent total knee (TKA) arthroplasty. We prospectively collected preoperative demographic and SF-12 and WOMAC data on 128 TKAs and 70 UKAs. Postoperatively, SF-12 and WOMAC outcomes were recorded during annual follow-up visits. At baseline, patients who underwent UKA had a higher Charlson Comorbidity Index than patients who underwent TKA; otherwise, preoperative characteristics were similar. At a mean follow-up of 3.0 years for UKA and 2.9 years for TKA, patients who underwent UKA reported higher SF-12 physical component and mental component scores and WOMAC pain/stiffness/physical function scores (confirmed with multivariate analysis). Furthermore, patients who underwent UKA had significantly larger improvements in both SF-12 outcomes and WOMAC pain and physical function scores from baseline than did patients who underwent TKA.
本研究比较了行单髁膝关节置换术（UKA）和全膝关节置换术（TKA）的患者的 12 项简明健康调查量表（SF-12）和西部安大略省和麦克马斯特大学骨关节炎指数（WOMAC）评估的结局。我们前瞻性地收集了 128 例 TKA 和 70 例 UKA 的术前人口统计学、SF-12 和 WOMAC 数据。术后，在每年的随访中记录 SF-12 和 WOMAC 结果。在基线时，行 UKA 的患者的 Charlson 合并症指数高于行 TKA 的患者；否则，术前特征相似。UKA 的平均随访时间为 3.0 年，TKA 为 2.9 年，行 UKA 的患者报告的 SF-12 生理成分和心理成分评分以及 WOMAC 疼痛/僵硬/躯体功能评分更高（经多变量分析证实）。此外，与行 TKA 的患者相比，行 UKA 的患者在 SF-12 结局和 WOMAC 疼痛和躯体功能评分方面的改善幅度明显更大。
