The meniscus is a biconcave fibrocartilage in the knee joint interpose between the femoral condyles and tibial plateau; the meniscus has functions in load bearing, load transmission, shock absorption joint stability, joint lubrication, and joint congruity.
The aim of this study is to provide orthopeadic surgeon a base of reference in the choice of the optimal course of management for meniscal tears.
One hundred and seventeen patients met the criteria of inclusion for the present study. Patients were divided in two groups T and NT according to the presence of distinct previous traumatic events to the knees. Two subgroups were formed in each groups T and NT respectively at a mean follow up of 1 and 4 years. Postoperative clinical outcome were assessed using Lysholm scores and Rand SF-36 survey.
One hundred and seventeen patients were included in the present study with 60(51.28%) patients in the traumatic group and 57(48.71%) in the degenerative group. 95(81.19%) patients in total were satisfied with their health status at end of follow up. The mean value of Lysholm scores at 1 year were respectively 85.25±8.78 for traumatic group and 86.38±12.14 for non-traumatic group and at 4 years were respectively 92.63±7.31 for traumatic group and 72.90±20.77 for non-traumatic group. According to Rand SF-36 health, traumatic group showed better improvements compare to non-traumatic group between 1 and 4 years after arthroscopic meniscus surgery.
A total of 95(81.19%) patients in total were satisfied with their health status at follow up, however, we found that arthroscopy as a treatment for meniscal tear have a relatively better mid-term clinical outcome for traumatic meniscal tears compare to non-traumatic/degenerative meniscal tears.
半月板是膝关节内的双凹形纤维软骨，位于股骨髁和胫骨平台之间；半月板具有承重、负荷传递、减震、关节稳定、关节润滑和关节一致性等功能。
本研究的目的是为骨科医生在选择半月板撕裂的最佳治疗方案时提供参考依据。
117例患者符合本研究的纳入标准。根据膝关节既往是否有明显创伤事件，将患者分为T组和NT组。T组和NT组分别在平均随访1年和4年时形成两个亚组。采用Lysholm评分和Rand SF-36调查问卷评估术后临床结果。
本研究共纳入117例患者，其中创伤组60例（51.28%），退变组57例（48.71%）。随访结束时，共有95例（81.19%）患者对其健康状况满意。创伤组1年时Lysholm评分的平均值分别为85.25±8.78，非创伤组为86.38±12.14；4年时创伤组分别为92.63±7.31，非创伤组为72.90±20.77。根据Rand SF-36健康调查，在关节镜下半月板手术后1至4年，创伤组比非创伤组显示出更好的改善。
随访时共有95例（81.19%）患者对其健康状况满意，然而，我们发现与非创伤性/退变性半月板撕裂相比，关节镜治疗创伤性半月板撕裂具有相对较好的中期临床结果。
