Anterior Cruciate Ligament Injury in Association With Other Knee Injuries in King Abdulaziz University Hospital, Saudi Arabia.

Purpose The purpose of this study was to study the association of anterior cruciate ligament (ACL) injury with meniscal, collateral ligament, and bone injuries using magnetic resonance imaging (MRI) for clinical correlation during ACL repair. Methods This was a retrospective cohort study conducted on 136 patients diagnosed with ACL injury by MRI at King Abdulaziz University Hospital (KAUH) between September 2010 and September 2018. Results The medial meniscus was injured in approximately half (49.3%) of patients, while the lateral meniscus was injured in 16.2%. Regarding collateral ligament injuries, the medial collateral ligament was injured in six patients (4.4%), the lateral collateral ligament in four patients (2.9%), and both collateral ligaments in three patients (2.2%). There was a significant relationship between the age group and the side of ACL injury (P<0.05) but not between the age group and the presence of an associated injury. Conclusion There was no significant relationship between ACL injury and menisci, collateral ligament, or bone injury.
