Abstract

Introduction

The outcomes of unicompartmental knee arthroplasty (UKA) in the presence and absence of medial meniscus posterior root tears (MMPRTs) have not been compared. This study compared the characteristics and clinical outcomes of patients undergoing UKA with and without MMPRTs.

Materials and methods

This study analyzed 68 patients. The presence or absence of MMPRTs was evaluated using preoperative magnetic resonance imaging. Patient characteristics, clinical scores before surgery and at the final evaluation, and imaging findings were compared between patients with and without MMPRTs. Multiple regression analysis was conducted on postoperative visual analog scale (VAS)-pain scores.

Results

MMPRTs were present in 64.7% (44/68) of patients. Patients with MMPRTs were significantly younger (67.8 ± 8.2 vs. 75.0 ± 7.1 years, p < 0.001) and had a shorter duration from the development of symptoms to the time of surgery than those without (6.8 ± 8.4 vs. 36.1 ± 38.9 months, p < 0.001). Component placement or lower-limb alignment did not significantly differ between the groups. Preoperative clinical scores were not significantly different between the groups; however, patients with MMPRTs showed significantly better postoperative VAS-pain scores than those without (10.0 ± 9.0 vs. 28.2 ± 26.0 points, p = 0.026). Multiple regression analysis of postoperative VAS-pain scores revealed the significant effect of duration from the development of symptoms to the time of surgery (p = 0.038).

Conclusions

Patients undergoing UKA with MMPRTs were younger with less radiographic osteoarthritic changes compared to those without MMPRTs, and their postoperative VAS-pain scores were significantly superior. The duration from the development of symptoms to the time of surgery significantly influenced postoperative pain in patients undergoing UKA.

内侧半月板后根撕裂合并晚期骨关节炎或软骨下不全性骨折是至少2年随访的单室膝关节置换术的良好适应症

目前还没有对存在和不存在内侧半月板后根撕裂（MMPRTs）的单室膝关节置换术（UKA）的结果进行比较。本研究比较了有和没有MMPRTs的UKA患者的特征和临床结果。材料与方法本研究对68例患者进行分析。术前磁共振成像评估MMPRTs的存在或不存在。患者特征、术前和最终评估时的临床评分以及影像学结果在接受和不接受MMPRTs的患者之间进行了比较。对术后视觉模拟量表(VAS)-疼痛评分进行多元回归分析。结果64.7%（44/68）的患者存在smmprts。接受MMPRTs治疗的患者明显更年轻（67.8±8.2岁vs 75.0±7.1岁，p < 0.001），从症状出现到手术时间也比没有接受MMPRTs治疗的患者短（6.8±8.4个月vs 36.1±38.9个月，p < 0.001）。各组间假体放置或下肢对齐无显著差异。两组术前临床评分差异无统计学意义；然而，MMPRTs患者术后VAS-pain评分明显优于未接受MMPRTs治疗的患者（10.0±9.0分比28.2±26.0分，p = 0.026）。术后VAS-pain评分的多元回归分析显示，从症状出现到手术时间的持续时间对患者有显著影响（p = 0.038）。结论与未接受MMPRTs治疗的患者相比，接受MMPRTs治疗的患者更年轻，骨关节炎影像学改变更少，术后VAS-pain评分明显优于未接受MMPRTs治疗的患者。从症状出现到手术时间的持续时间显著影响UKA患者的术后疼痛。
