Abstract:
Objective To evaluate the morphological and signal intensity changes after anterior cruciate ligament reconstruction , and to analyze the correlations between MRI evaluation and clinical examination .Methods Totally 34 patients who underwent anterior cruciate liga-ment reconstruction in our hospital from July 2013 to June 2015 were given MRI examination .The morphology ,orientation and signal intensity of the anterior cruciate ligament grafts were evaluated on axial ,sagittal and coronal images .The grafts were assessed with Rak method ,and the clinical assessment was adopted with physical assessment method ,including drawer test ,axial shift test and Lachman test .The correlations be-tween MRI evaluation and clinical examination results were further analyzed by SPSS 16.0.Results After anterior cruciate ligament recon-struction,79%of the graft were visualized as a smoothly continuous low signal (well-defined type),15%of the graft showed increased signal intensity with only a small part of low signal bands ( intermediate type ) ,and 6% of the grafts showed remarkably increased signal intensity (indiscernible type).A statistically significant correlation was identified in MRI evaluation and clinical examination results (P<0.05). Spearman’ s correlation coefficient was 0.747 2 which indicating significantly positive correlation .Conclusion Magnetic resonance imaging is a noninvasive high-resolution imaging technology and it is an effective tool for evaluating anterior cruciate ligament reconstruction .
