PURPOSE
The effect of quadriceps muscle strength on medial joint space (MJS) narrowing after repair for medial meniscus (MM) posterior root tears (MMPRTs) has not yet been determined. This study aimed to evaluate the effect of preoperative and postoperative quadriceps muscle strength on the change in MJS (ΔMJS) in MMPRTs.
METHODS
Thirty patients who underwent pullout repair for MMPRTs were retrospectively evaluated. The MJS width using fixed-flexion view radiographs, MM extrusion (MME) using magnetic resonance imaging, quadriceps muscle strength using the Locomo Scan-II and clinical scores were measured and compared preoperatively and 1 year postoperatively. Correlations between the ΔMJS, change in MME (ΔMME), and preoperative and postoperative quadriceps muscle strength were evaluated using Spearman's rank correlation coefficient.
RESULTS
MJS narrowing and MME progressed significantly at 1 year postoperatively ( < 0.001). Quadriceps muscle strength in MMPRT knees and all clinical scores significantly improved at 1 year postoperatively ( < 0.001). ΔMJS and ΔMME showed a significant positive correlation (0.50 ± 0.70 and 1.22 ± 0.92 mm, respectively; = 0.516, = 0.004). Both preoperative and postoperative quadriceps muscle strength in MMPRT knees showed significant negative correlations with ΔMJS (preoperative: = -0.529, = 0.003; postoperative: = -0.477, = 0.008) and ΔMME (preoperative: = -0.431, = 0.018; postoperative: = -0.443, = 0.014).
CONCLUSIONS
In pullout repair for MMPRTs, preoperative and postoperative quadriceps muscle strength in MMPRT knees was negatively correlated with the progression of MJS narrowing and MME. Rehabilitation with a focus on quadriceps muscle strengthening, including preoperative rehabilitation, may delay knee-osteoarthritis progression after pullout repair for MMPRTs.

目的
股四头肌力量对内侧半月板后根撕裂（MMPRTs）修复术后内侧关节间隙（MJS）变窄的影响尚未确定。本研究旨在评估术前和术后股四头肌力量对MMPRTs中MJS变化（ΔMJS）的影响。
方法
回顾性评估30例行MMPRTs拉出修复术的患者。使用固定屈曲位X线片测量MJS宽度，使用磁共振成像测量半月板挤出（MME），使用Locomo Scan-II测量股四头肌力量，并在术前和术后1年比较临床评分。使用Spearman等级相关系数评估ΔMJS、MME变化（ΔMME）与术前和术后股四头肌力量之间的相关性。
结果
术后1年MJS变窄和MME显著进展（<0.001）。MMPRT膝关节的股四头肌力量和所有临床评分在术后1年显著改善（<0.001）。ΔMJS和ΔMME呈显著正相关（分别为0.50±0.70和1.22±0.92mm；=0.516，=0.004）。MMPRT膝关节术前和术后的股四头肌力量与ΔMJS（术前：=-0.529，=0.003；术后：=-0.477，=0.008）和ΔMME（术前：=-0.431，=0.018；术后：=-0.443，=0.014）均呈显著负相关。
结论
在MMPRTs的拉出修复术中，MMPRT膝关节术前和术后的股四头肌力量与MJS变窄和MME的进展呈负相关。以股四头肌强化为重点的康复治疗，包括术前康复，可能会延缓MMPRTs拉出修复术后膝骨关节炎的进展。
