ABSTRACT
Objective Risk factor of radial and horizontal tear for posterior horn of medial meniscus is analyzed in present study.Methods A total of 390 patients diagnosed with medial meniscus tear received during January 2011 to December 2012 were of retrospective analysis.94 cases with radial tear of medial meniscus posterior horn and 95 horizontal cases were chosen as research objects.Age,gender,duration of symptoms,body weight index,trauma history,posterior slop of tibia plateau,knee valgus angle and Outerbridge cartilage classification of patients with radial or horizontal tear were recorded and analyzed.Multifactor unconditioned Logistic regression analysis was employed to analyze risk factor of meniscus radial tear.Results Significant difference could be spotted in the analysis of gender (x2=9.059,P=0.003),body weight index (t=2.549,P=0.012),knee valgus angle (t=-5.609,P=0.000) and Outerbridge cartilage classification (x2=42.300,P=0.000) between patients with radial or horizontal tear.Meanwhile,no significant difference could be spotted in the analysis of trauma history (x2=0.368,P=0.544),posterior slop of tibia plateau (x2=1.021,P=0.312),age (t=-1.228,P=0.221) and symptom duration (t=0.272,P=0.786).According to the results of multi-factor analysis,valgus angle (OR=12.581,P=0.001),age (OR=0.875,P=0.026) and Outerbridge cartilage classification (OR=33.790,P=0.000; OR=15.558,P=0.000; OR=39.891,P=0.000; OR=91.041,P=0.000) were risk factors of meniscus radial tear.Conclusion High incidence of posterior horn of medial meniscus tear was found in patients with senile osteoarthritis.The incidence of radial tear of medial meniscus posterior horn in elderly patients with knee varus or serious articular cartilage was higher than that of horizontal tear.
