Automated, Accurate, and Three-dimensional Method for Calculating Sagittal Slope of the Tibial Plateau

Increased posterior-inferior directed slope of the subchondral bone of the lateral tibial plateau is a risk factor for noncontact rupture of the anterior cruciate ligament (ACL). However, previous measures of lateral tibial slope are variable from study-to-study and often lack documentation of their accuracy. These factors impede identifying the magnitude of lateral tibial slope that increases risk of noncontact ACL rupture. Therefore, we developed and evaluated a new method that: 1) requires minimal user input, 2) employs 3D renderings of the tibia that are referenced to a 3D anatomic coordinate system, and 3) is precise, reliable and accurate.
