Conclusion The morphological change of knee with transection of the medial collateral ligament and partial medial meniscectomy in the study demonstrated the characteristic OA, and the expression of TNF-α and IL-1 β in synovial fluid was increased at the same time. 第3周滑膜已出现明显的纤维化改变。结论:内侧副韧带切断伴内侧半月板部分切除后,大鼠膝关节呈现骨性关节炎的改变,关节液中IL-1β和TNF-α表达显著增高。
The position of knee point of Phase-frequency characteristic mean value curve is invariant, but the kurtosis of the curve near the knee point decreases. 刚度与质量参数随机时相频特性均值曲线的拐点位置不变,只是拐点附近曲线陡峭度减小。
