背景:本研究旨在评估内侧半月板(MM)后根修复后的股四头肌肌力,并确定其与临床评分和MM挤压(MME)的关系。
方法:本研究包括30例接受MM后根撕裂拔除修复术并在术前和术后1年评估股四头肌肌力的患者。使用LocomoScan-II仪器(ALCARE,东京,日本)。MME和临床评分(即,膝关节损伤和骨关节炎结果评分[KOOS],国际膝关节文献委员会得分,Lysholm得分,Tegner得分,和视觉模拟量表疼痛评分)在术前和术后1年进行评估,术后1年进行二次关节镜检查.使用Wilcoxon的符号秩检验来比较术前和术后的每个测量值。Pearson相关系数用于评估股四头肌肌力值的相关性。进行多元回归分析以确定与MME(ΔMME)变化相关的因素。
结果:关节镜检查证实所有患者后根的连续性。术后1年测得的股四头肌肌力(355.1±116.2N)相对于术前测量的股四头肌肌力(271.9±97.4N,p<0.001)。术后1年的MME(4.59±1.24mm)相对于术前的MME(3.63±1.01mm,p<0.001)。术后1年临床评分相对于术前评分显著改善(p<0.001)。术后股四头肌肌力与ΔMME相关(相关系数=-0.398,p=0.030),股四头肌肌力的变化与KOOS-生活质量相关(相关系数=0.430,p=0.018)。多元回归分析表明,即使包括体重指数和从受伤到手术的时间,术后股四头肌肌力也对ΔMME有显着影响。
结论:MM后根修复后,股四头肌肌力较大的患者MME进展较少.此外,股四头肌肌力改善较大的患者的临床评分较好;因此,建议在MM后根修复后继续进行旨在改善股四头肌肌力的康复。

BACKGROUND: This study aimed to assess quadriceps muscle strength after medial meniscus (MM) posterior root repair and determine its relationship with clinical scores and MM extrusion (MME).
METHODS: Thirty patients who underwent pullout repair for MM posterior root tear and were evaluated for quadriceps muscle strength preoperatively and at 1 year postoperatively were included in this study. Quadriceps muscle strength was measured using the Locomo Scan-II instrument (ALCARE, Tokyo, Japan). MME and clinical scores (i.e., Knee Injury and Osteoarthritis Outcome Score [KOOS], International Knee Documentation Committee score, Lysholm score, Tegner score, and visual analog scale pain score) were evaluated preoperatively and at 1 year postoperatively, and second-look arthroscopy was performed at 1 year postoperatively. Wilcoxon\'s signed-rank test was used to compare each measure pre- and postoperatively. Pearson\'s correlation coefficient was used to assess the correlation with quadriceps muscle strength values. Multiple regression analysis was performed to identify factors associated with the change in MME (ΔMME).
RESULTS: Second-look arthroscopy confirmed continuity of the posterior root in all patients. The quadriceps muscle strength measured at 1 year postoperatively (355.1 ± 116.2 N) indicated significant improvement relative to the quadriceps muscle strength measured preoperatively (271.9 ± 97.4 N, p < 0.001). The MME at 1 year postoperatively (4.59 ± 1.24 mm) had progressed significantly relative to the MME preoperatively (3.63 ± 1.01 mm, p < 0.001). The clinical scores at 1 year postoperatively were improved significantly relative to the scores preoperatively (p < 0.001). The postoperative quadriceps muscle strength was correlated with ΔMME (correlation coefficient = -0.398, p = 0.030), and the change in quadriceps muscle strength was correlated with the KOOS-Quality of Life (correlation coefficient = 0.430, p = 0.018). Multiple regression analysis showed that the postoperative quadriceps muscle strength had a significant effect on ΔMME even when the body mass index and time from injury to surgery were included.
CONCLUSIONS: After MM posterior root repair, patients with greater quadriceps muscle strength showed less MME progression. In addition, patients with greater improvement in quadriceps muscle strength had better clinical scores; therefore, continued rehabilitation aimed at improving quadriceps muscle strength after MM posterior root repair is recommended.
