摘要: Background:Injuries to the anterior cruciate ligament (ACL) are common, and a number of knee morphological variables have been identified as risk factors for an ACL injury, including posterior tibial slope (TS). However, limited data exist regarding innate population differences in TS.Purpose:To (1) establish normative values medial lateral TS; (2) determine what between ages, sexes, races; (3) how internal or external rotation (as occurs during sagittal motion) influences stereotactic perception TS.Study Design:Cross-sectional study; Level evidence, 3.Methods:A total 545 cadaveric specimens (1090 tibiae) were obtained from Hamann-Todd osteological collection. Specimens leveled coronal, sagittal, axial planes using digital laser. Virtual representations each bone created with 3-dimensional digitizer apparatus. The TS plateaus measured te...
