Editorial Commentary: The Ratio of Tibial Slope and Meniscal Bone Angle is a Strong Predictor for Anterior Cruciate Ligament Injury: A Steep Hill and a Shallow Speed Bump are a Hazardous Combination
The lateral tibial posterior slope (LTPS) and the lateral meniscal bone angle (MBA) are important geometrical features of the knee joint and have therefore been of interest in the setting of anterior cruciate ligament injury (ACL) and ACL reconstruction. An emerging body of evidence suggests that LTPS is an independent risk factor for primary and recurrent ACL injury. Furthermore, biomechanical and clinical evidence is emphasizing the crucial contribution of the lateral meniscus to rotatory knee stability. Thus, not surprisingly, the MBA has also been shown to be an independent risk factor regarding ACL injury. The ratio of LTPS and MBA is a relatively new idea but has shown to be highly predictive for primary and recurrent ACL injury and may be used to identify patients at high risk of ACL reconstruction failure.
