Abstract
Objective: Anterior Cruciate Ligament (ACL) tear can decrease quality of life especially in athlete. The physical athletic activities are external factors for ACL tear. There are also internal factor and one them is anatomical factor. Therefore, it is necessary to determine the knee morphometric risk factor profile for ACL tear. Materials and Methods: This is a descriptive observational retrospective study with case-control design. The study data consisted of the patient's medical records and knee joint MRI study results which were collected through consecutive sampling. Morphometric variable measurements in the form of Notch Width (NW), Notch Width Index (NWI), ? -angle, Q-angle (Quadricep angle) and Medial Tibial Posterior Slope (MTPS) were assessed by two assessors. Afterwards, the mean value of each variable was determined. Results: In ACL tear group, the mean±SD value for NW, NWI, Alpha angle, Q-angle and MTPS was 2.02±0.21, 0.27±0,02, 37.97±4.69, 11.06±3.21, and 9.24±2.73, respectively, while in non-ACL tear group the mean±SD value was 1.97±0.23, 0.29±0.02, 35.59±4.52, 12.03±4.08 and 7.70±3.53, respectively. Conclusion: The mean NWI and Q-angle values in ACL tear group were smaller than in non-ACL tear group. The mean NW, Alpha angle, and MTPS values in ACL group were greater than in non-ACL tear group.
