Anterior cruciate ligament (ACL) rupture is one of the most frequently encountered traumatic ligamentous lesions of the knee. Several intrinsic and extrinsic factors are linked to this lesion. Anatomical factors increase the anterior translation of the knee and thus promote the stretching and rupture of the anterior cruciate ligament. Objectives: To determine the anatomical risk factors favouring ACL rupture by comparing morphometric parameters of patients with knee ACL rupture to patients without ACL rupture, as well as the intercondylar notch index and the tibial slopes of the two groups and describing the ruptured ACLs and associated signs. Materials and Methods: We conducted a case-control descriptive analytical study in imaging centres of the General Henri Mondor of Aurillac Hospital Centre in France (CHM) and the Jordan Medical Centre of Yaoundé in Cameroon (CMJ). MRI exam protocols included T1 SE, T2 SE, proton density and Fat Sat sequences, with slices in all three planes. Morphometry knee variables measured in our study were: intercondylar notch index and the tibial slopes. These measurements were obtained from images stored in DICOM format and post processing software OsiriX MD ® for CMJ patients and Explore ® for CHM patients. Results: The study included 92 individuals, 38 in the case group and 54 in the control group. The mean age was 36.6 years for both groups; 35.5 years for the cases and 37.4 years for the controls. The sex ratio was 1.87 men for 1 woman in

The purpose of this study was to determine if geometry of the articular surfaces of the tibial plateau is associated with non-contact anterior cruciate ligament (ACL) injury. This was a longitudinal cohort study with a nested case-control analysis. Seventyeight subjects who suffered a non-contact ACL tear and a corresponding number of controls matched by age, sex, and sport underwent 3 T MRI of both knees. Surface geometry of the tibial articular cartilage was characterized with polynomial equations and comparisons were made between knees on the same person and between ACL-injured and control subjects. There was no difference in surface geometry between the knees of the control subjects. In contrast, there were significant differences in the surface geometry between the injured and normal knees of the ACL-injured subjects, suggesting that the ACL injury changed the cartilage surface profile. Therefore, comparisons were made between the uninjured knees of the ACL-injured subjects and the corresponding knees of their matched controls and this revealed significant differences in the surface geometry for the medial (p < 0.006) and lateral (p < 0.001) compartments. ACL-injured subjects tended to demonstrate a posterior-inferior directed orientation of the articular surface relative to the long axis of the tibia, while the control subjects were more likely to show a posterior-superior directed orientation. Severe knee injury, such as an anterior cruciate ligament (ACL) disruption, is often immediately disabling and has been associated with the early onset of post-traumatic osteoarthritis regardless of whether surgical or non-surgical treatment is chosen.1,2 This has motivated studies that have focused on identifying the variables associated with increased risk of ACL injury, so that prevention strategies can be developed and those at increased risk can be identified and targeted for intervention. 3During the process of suffering an ACL injury, the geometry of the articular surfaces of the knee is important in controlling the biomechanical response of the tibiofemoral joint and ACL. 4,5 For example, there appears to be a consensus forming in the literature that individuals who are at increased risk of suffering non-contact ACL disruptions have increased posteriorinferior directed slopes of the subchondral bone portion of their tibial plateaus compared to uninjured controls. [6][7][8][9][10][11][12][13][14][15][16] This relationship is important because the magnitude of ACL strain values produced by impulsive loading of the knee during common sportsrelated movements such as jump landings are directly related to the posterior-inferior directed slope of the subchondral bone of the proximal tibia. 4,17,18 Most of what is known about the relationship between the risk of suffering non-contact ACL injury and joint geometry has come from studies of the underlying subchondral bone of the tibia plateau; however, the large inter-segmental forces that are transmitted between the femur and tibia occur across the surface o...
