In recent years, medial meniscus (MM) posterior root tears (PRT) have received increasing attention due to their association with rapidly progressive knee osteoarthritis. MM posterior root (PR) repair has been reported to yield good clinical outcomes, but no study has yet to compare the postoperative outcomes after MMPR repair between sexes. The purpose of this study is evaluating the postoperative clinical outcomes following MMPR pullout repair by sex.
Eighty-six patients who underwent pullout repair for isolated MMPRTs at our institution between October 2016 and November 2019 were evaluated. Patients were divided into two groups according to sex, and their clinical outcomes were compared preoperatively and at 2 years postoperatively.
The cohort was comprised of 21 male and 65 female patients. Three factors related to physical status (height (p < 0.01), body weight (p < 0.01), and BMI (p = 0.02)) were significantly higher in male patients. No significant differences were observed in preoperative clinical scores between male and female. All clinical scores significantly improved at 2 years postoperatively in both sexes. In the clinical scores, the KOOS-symptom (p = 0.03), KOOS-QOL (p = 0.03), and Tegner activity scores (p < 0.01) showed significantly better scores in male patients.
Following MMPR pullout repair, the clinical outcomes significantly improved in both sexes. These results indicate that MMPR pullout repair is a universally effective technique regardless of the disadvantages of females in morphological characteristics.
近年来，内侧半月板（MM）后根撕裂（PRT）因其与快速进展的膝关节骨关节炎相关而受到越来越多的关注。据报道，MM后根（PR）修复可产生良好的临床效果，但尚无研究比较性别之间MM后根修复术后的结果。本研究的目的是按性别评估MM后根拉出修复术后的临床结果。
对2016年10月至2019年11月在本机构接受孤立性MM后根撕裂拉出修复的86例患者进行评估。根据性别将患者分为两组，并比较术前和术后2年的临床结果。
该队列包括21例男性和65例女性患者。男性患者的三个与身体状况相关的因素（身高（p < 0.01）、体重（p < 0.01）和BMI（p = 0.02））显著更高。男女术前临床评分无显著差异。术后2年，男女的所有临床评分均显著改善。在临床评分中，男性患者的KOOS症状（p = 0.03）、KOOS生活质量（p = 0.03）和Tegner活动评分（p < 0.01）显示出显著更好的分数。
MM后根拉出修复术后，男女的临床结果均显著改善。这些结果表明，无论女性在形态特征上存在何种劣势，MM后根拉出修复都是一种普遍有效的技术。
