Abstract
Background: The knee joint's stability relies significantly on the integrity of the meniscus and the anterior cruciate ligament (ACL). Chronic ACL tears can compromise knee stability, making the meniscus a crucial stabilizer. Understanding the prevalence and patterns of meniscus injuries associated with chronic ACL tears is essential for effective management. Objective: This study aimed to assess the arthroscopic evaluation of association of meniscus injuries in patients with anterior cruciate ligament injuries. Method: A retrospective analysis was conducted on thirty-three patients diagnosed with ACL injuries at MuMCH between January 2021 and December 2023. Patients aged 18-50 with ACL injuries, with or without meniscus damage, were included. Clinical evaluations, knee MRI scans, and diagnostic knee arthroscopies were performed. The study evaluated meniscus injuries associated with chronic ACL injuries and assessed outcomes using the modified Lysholm score. Results: The study revealed a predominant occurrence of meniscus injuries (70%) among participants, with a majority falling within the 38-47 years age bracket (45.45%) and a male majority (60%). Sports and accidental injuries accounted for 40% each, while road traffic accidents contributed 20%. Lateral meniscus tears were the most prevalent (30.30%), followed by combined medial and lateral meniscus tears (33.33%). Posterior horn tears were predominant, particularly in the medial meniscus. Conclusion: The study highlights a high incidence of meniscus injuries associated with chronic ACL tears, with medial meniscus injuries prevailing over lateral tears. Posterior horn tears were predominant, emphasizing the medial meniscus's significant role in knee stability. These findings underscore the importance of early detection and appropriate management of meniscus injuries in chronic ACL-deficient knees to prevent degenerative changes and optimize patient outcomes.
