Objective: Preceding studies to date have assessed the relationship between anterior cruciate ligament (ACL) tears and other related injuries without evaluating the ACL tear as partial or complete. In this study, we aimed to investigate the relationship between the type of an ACL tear assessed with magnetic resonance imaging and demographic factors, injury characteristics, and concomitant injuries.
Material and Methods: A retrospective cohort study was performed on patients admitted to the Sports Medicine Outpatient Clinic. The diagnosis of ACL tear was based on magnetic resonance imaging. Of the 310 patients with an acute ACL injury, 90 patients diagnosed with ACL tear by magnetic resonance imaging were divided into two groups according to the tear type; partial (n=26) and complete tear (n=64). Demographic factors, injury characteristics and meniscal, articular cartilage, collateral ligament, and posterior cruciate ligament lesions confirmed by magnetic resonance imaging were recorded.
Results: The mean age of the participants was 27.2 ± 7.9 years. Most of the patients (74.4%) were recreational athletes and football was the most common sports discipline (65.6%) among the patients. The most common accompanying injury was meniscal tear (61.1%), followed by articular cartilage damage (45.6%). There were no significant differences between partial tear and complete tear groups regarding incidence rates of injuries accompanying the ACL tear (p > 0.05 for all).
Conclusion: We found similar incidence rates of menisci, articular cartilage, collateral ligaments, and posterior cruciate ligament injuries associated with ACL tear among the partial ACL tear and the complete ACL tear groups.
