The effect of tibial slope in acute XXXX @entity1 on concurrent meniscal tears.

@entity1 @entity75 @entity1887 @entity39842 @entity130
INTRODUCTION: The aim of this study is to evaluate the effect of the medial and lateral posterior tibial slope (MPTS, @entity39842 ) in @entity1 with acutely ruptured ACL on the menisci. It was hypothesized that medial and lateral meniscus lesions are seen more often with high PTS (posterior tibial slope). We hypothesized that in case of a high tibial slope a possible @entity75 is more often located in the posterior horn of the meniscus than in knees with a low tibial slope. MATERIALS AND METHODS: We identified 537 @entity1 with ACL insufficiency between 2012 and 2013. Of these, 71 @entity1 were eligible for the study according to the study's criteria. PTS was measured via MRI and classified into two groups: >10   for high tibial slope and  <=10   for low tibial slope. Any @entity75 was documented during arthroscopic ACL reconstruction and evaluated regarding @entity75 patterns with high and low PTS, taking into account the type and the location of the tear (anterior horn, intermediate part and posterior horn). Statistical analysis for differences in @entity75 was performed using Chi-square tests and McNemar tests for dependent variables. The level of significance was set at p   <=  0.05. RESULTS: High PTS (MPTS and @entity39842 ) was associated with a higher incidence of @entity75 with an odds ratio of 2.11, respectively, 3.44; however, no statistical significance was found. Among the total number of @entity1887 knees studied, the @entity75 spread more often to the posterior part in the group with a low PTS. In contrast, less damage of the posterior horn of the meniscus could be found in the group with a high PTS. CONCLUSION: High PTS seems to predetermine for @entity75 in an acute @entity1887 knee. More damage to the posterior part of the menisci could generally be seen but was not associated with a high PTS. There was no statistical significance to support the initial hypothesis. Further research is needed to find out if factors other than tibial slope are risk factors for @entity75 in acute @entity130 . LEVEL OF EVIDENCE: IV.
