Association of tibia eminence width index and intercondylar notch angle with risk of anterior cruciate ligament injury in an African population

Abstract

Background: Certain modifiable and nonmodifiable risk factors have been associated with the risk of suffering an anterior cruciate ligament (ACL) rupture. The goal of this study was to determine the relationship between the intercondylar notch angle (INA) and the tibia
eminence width index (TEWI), with the risk of ACL injury. Materials and Methods: Consecutive patients with ACL injury presenting over a 3‑year period were recruited. Acontrol group with no complaints related to cruciate and collateral knee ligament injuries was also recruited. Results: The mean values of each of these variables were compared between the groups. The body mass index, height, and weight were correlated with TEWI and INA in each group. A total of 30 each of ACL injured cases and controls were recruited for the study. The mean values of the TEWI for the ACL group were 0.20 and 0.19 for the control group (P = 0.553). The mean INA for ACL is 43.37° and 42.43° for control (P = 0.969). Conclusion: The INA and TEWI are not predictive of the risk of ACL injury.
