前交叉韧带断裂后股骨髁间窝的MRI测量及其相关性

MRI Measurement and Its Correlation Between The Femoral Condyle and the Femoral Condyle After the Rupture of the Anterior Vruciate ligament

目的:应用MRI定量检测前交叉韧带断裂与股骨髁间窝解剖形态变化的关系。方法:40例单侧膝关节前交叉韧带断裂患者,将患侧膝关节作为观察组,健侧作为对照组,对双膝关节股骨髁间窝相关参数进行MRI测量。结果:观察组的髁间窝宽度(ICW)显著小于对照组(P<0.05),而两组的髁间窝高度(ICH)和股骨髁宽度(EW)的比较,差异无统计学意义(P>0.05)。观察组的髁间窝宽度指数(NSI)及髁间窝形态指数(NWI)均显著低于对照组,差异有统计学意义(P<0.05)。两组膝关节功能评分的Lysholm评分和Tegner评分均无统计学差异(P>0.05)。结论:对前交叉韧带断裂后的股骨髁间窝解剖关系MRI检测,可有重要意义。

Objective： To quantitatively detect the relationship between the fracture of the anterior cruciate ligament and the ana- tomic changes of the femoral condyle in the femoral condyle by MRI. Methods： 40 patients with unilateral knee joint anterior cruciate ligament rupture, the knee joint as the observation group, the healthy side as the control group, the MRI measurement of the parame- ters of the femoral condyle of the knee joint. Results： the width of the mandibular condyle （ICW） in the observation group was signifi- cantly less than that in the control group （P 〈 0.05）, while the difference between the two groups of the mandibular condyle （ICH） and the femoral condyle width （EW） was not statistically significant （P 〉 0.05）. The difference of the Lysholm score and Tegner score of the two groups was statistically significant （P 〈 0.05）. Conclusion： the anatomic relationship between the posterior cruciate ligament （NWI） and MRI （P） was significant.
