摘要

目的：股四头肌力量对内侧半月板（MM）后根撕裂（MMPRTs）修复后内侧关节间隙（MJS）狭窄的影响尚未确定。本研究旨在评估术前和术后股四头肌力量对MMPRTs中MJS变化的影响（ΔMJS）。方法：对30例MMPRTs拔牙修复患者进行回顾性分析。采用固定屈曲透视片测量MJS宽度，采用磁共振成像测量MM挤压（MME），采用Locomo Scan-II测量股四头肌力量和临床评分，并对术前和术后1年进行比较。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肌力之间的相关性。结果：术后1年MJS变窄和MME进展明显（p pr = 0.516, p = 0.004）。MMPRT膝关节术前和术后股四头肌肌力与ΔMJS呈显著负相关(术前：r = -0.529, p = 0.003；术后：r = -0.477, p = 0.008)和ΔMME(术前：r = -0.431, p = 0.018；术后：r = -0.443, p = 0.014)。结论：在MMPRT拔除修复中，术前和术后MMPRT膝关节的股四头肌肌力与MJS变窄和mme的进展呈负相关。康复以股四头肌肌肉强化为重点，包括术前康复，可能会延迟MMPRT拔除修复后膝关节骨性关节炎的进展。证据等级：四级。

Quadriceps muscle strength of the affected limb in medial meniscus posterior root tears is negatively correlated with the progression of postoperative medial joint space narrowing

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 (p < 0.001). Quadriceps muscle strength in MMPRT knees and all clinical scores significantly improved at 1 year postoperatively (p < 0.001). ΔMJS and ΔMME showed a significant positive correlation (0.50 ± 0.70 and 1.22 ± 0.92 mm, respectively; r = 0.516, p = 0.004). Both preoperative and postoperative quadriceps muscle strength in MMPRT knees showed significant negative correlations with ΔMJS (preoperative: r = −0.529, p = 0.003; postoperative: r = −0.477, p = 0.008) and ΔMME (preoperative: r = −0.431, p = 0.018; postoperative: r = −0.443, p = 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.
