膝关节退行性变模型及松解疗法对其影响

Knee joint degeneration model and effect of the loosening therapy on it

摘要:

目的观察膝关节退行性变模型经松解局部挛缩组织治疗前、后变化,探讨其治病机理.方法30只家兔随机分为正常对照组、模型空白组及模型治疗组各10只.观察各组大体解剖、X光片及膝关节被动活动度的变化.结果模型治疗组膝关节被动活动度与模型空白组及正常组比较,差异均具有统计学意义(P＜0.05);肉眼观察膝关节及X线稍有变化.结论局部松解可改善实验性膝关节退行性变模型的被动活动度.

Abstract:

Objective: To probe into the therapeutic mechanism of loosing therapy by observing the changes of knee joint degeneration model before and after its contracted tissues were locally loosened. Methods: Thirty-six rabbits were divided into three groups at random: 10 in the normal group, 10 in the blank model group and 10 in the loosening therapy group to observe the change of the range of the passive knee movement in each group through gross anatomy and x-rays. Results: After the passive movement in the model therapy group was compared with that of the blank model group and the normal group, the difference had the statistic significance (P<0.05). A slight change was found in the knee joint and x-rays with the naked eyes. Conclusion: The local loosening therapy can improve the range of passive movement of the experimental knee joint degeneration model.
