Purpose The aim of this retrospective study was to investigate the effectiveness of medial unicompartmental knee arthroplasty (UKA) by showing the results of the radiological and clinical outcomes of the patients. Materials and methods Seventy-two knees of 54 patients who underwent UKA between September 2005 and March 2011 for medial knee arthritis with a minimum follow-up of six months were evaluated. Range of motion (ROM), Hospital for Special Surgery (HSS) knee score, Knee Society Score (KSS), and Oxford Knee Score (OKS) were investigated both preoperatively and postoperatively. On the other hand, Oxford radiographic evaluation criteria were used to evaluate prostheses radiologically at the final follow-up. Results The average age was 53.4 years (47 to 79 years). The average follow-up time was 39.8 months (8 to 72 months). There was a significant difference between preoperative and postoperative ROM, HSS, and OKS (p<0.05). Radiologically, there was no sign of arthritis on the unoperated side of the knee or failure of prosthesis detected. Before the operation, the average clinical KSS was 63.2 and improved to 91.4 after the operation. In addition, the average functional KSS was 54.9 before the operation and improved to 86.5 after the operation. The average knee flexion degree was 109.1 before the operation and there was an improvement to 123.6 degrees after the operation. Before the operation, the average HSS score was 67.5 (range, 52 to 75) and improved to 89.9 (range, 85 to 100) at the final control examination. Conclusion This study supports the use of Oxford Phase 3 UKA, which has excellent clinical and radiological results in patients with medial knee arthritis.
目的 本回顾性研究的目的是通过展示患者的放射学和临床结果来调查内侧单髁膝关节置换术（UKA）的有效性。材料与方法 对2005年9月至2011年3月期间因内侧膝关节关节炎接受UKA治疗且随访至少6个月的54例患者的72个膝关节进行评估。术前和术后均调查活动范围（ROM）、特种外科医院（HSS）膝关节评分、膝关节协会评分（KSS）和牛津膝关节评分（OKS）。另一方面，在最后随访时使用牛津放射学评估标准对假体进行放射学评估。结果 平均年龄为53.4岁（47至79岁）。平均随访时间为39.8个月（8至72个月）。术前和术后的ROM、HSS和OKS之间存在显著差异（p<0.05）。放射学检查显示，膝关节未手术侧无关节炎迹象，也未检测到假体失败。手术前，临床KSS平均为63.2，术后提高到91.4。此外，手术前功能KSS平均为54.9，术后提高到86.5。手术前膝关节平均屈曲度为109.1，术后改善到123.6度。手术前，HSS平均评分为67.5（范围为52至75），在最后一次对照检查时提高到89.9（范围为85至100）。结论 本研究支持使用牛津3期UKA，其在内侧膝关节关节炎患者中具有优异的临床和放射学结果。
