methods: 234 cases medial meniscus of 3~9 months fetus were observed and measured by anatomical methods.

方法：用解剖学方法对234例3~9个月胎儿内侧半月板进行了形态学观察和测量。

surgery group and ct intervened group were intervened by cutting off the anterior cruciate ligament and the medial meniscus of their right knees, while the left knees as the control samples.

对手术组与ct干预组的右膝行前交叉韧带切断加内侧半月板切除术，左膝作为空白对照，不予手术。

objective:to accumulate the morphological documents of medial meniscus of fetus and explore its growing rules; also to provide data for medial meniscus of fetus transplantation.

前言：目的：积累国人胎儿内侧半月板的形态学资料以探索其生长规律，同时为以胎儿内侧半月板为供体的移植研究提供数据支持。

the posterior horn of the medial meniscus was avulsed from its insertion and knees were retested.

内侧半月板后角从插入点撕脱，重新测量膝关节。

background: tears of the posterior root of the medial meniscus are becoming increasingly recognized. they can cause rapidly progressive arthritis, yet their biomechanical effects are not understood.

背景：内侧半月板后角撕裂能很快导致退行性关节炎，正日益受到关注，但其生物力学特性尚不清楚。

conclusion:(1) the operation on tibial collateral ligament , anterior cruciate ligament, posterior cruciate ligament and medial meniscus in the left knees in rabbits can produce model of oa;

结论：（1）采用手术破坏新西兰兔膝关节内侧副韧带、前后交叉韧带、内侧半月板，强迫其运动的方法可建立膝关节骨性关节炎的动物模型；

conclusion rather good therapeutic effect can be achieved in treatment of discoid medial meniscus with arthroscopic plastic operation of meniscus.

结论关节镜下确诊内侧盘状半月板后实施成形术能获得优良的治疗结果。

the goal of this study was to determine the effects of posterior root tears of the medial meniscus and their repairs on tibiofemoral joint contact pressure and kinematics.

本研究旨在确定内侧半月板后角撕裂的生物力学特性，以及修复后对胫股关节接触压力和动力学的影响。

peripheral posterior horn tears of the medial meniscus occurred in 10 cases (56%, 10/18) were the main types of tear by a statistically significant amount in chronic period.

慢性期组内侧半月板后角损伤10例（5 6 % ，10 18） ，是该期半月板损伤的主要类型；
