Association Between Meniscal Tears and Anterior Cruciate Ligament (ACL) Tears Using MRI

Abstract

Introduction: Knee injuries, particularly anterior cruciate ligament (ACL) and meniscal tears, are common in active individuals, significantly affecting mobility and quality of life. ACL injuries often result in secondary meniscal damage due to disrupted knee biomechanics, increasing the likelihood of osteoarthritis. Prompt and accurate diagnosis, supported by advanced imaging techniques like MRI, is critical for guiding individualized treatment strategies to ensure optimal recovery and prevent long-term complications associated with these debilitating conditions. Objective: This study aims to investigate the association between ACL and meniscal tears, highlighting the role of magnetic resonance imaging (MRI) in enhancing diagnostic precision and treatment strategies. Methods: A cross-sectional study was conducted on 50 patients with suspected knee injuries referred for MRI at Narayana Medical College from January 2022 to October 2023. Clinical presentations and imaging findings were evaluated to identify patterns and correlations between ligamentous and meniscal injuries. Results: ACL tears were the most common ligamentous injury (58%), with partial tears (62%) being more prevalent than complete tears. Medial meniscus tears were the most frequent meniscal injuries (53.6%), predominantly affecting the posterior horn. Combined ACL and meniscal injuries were common, particularly in younger individuals involved in high-impact activities. MRI demonstrated exceptional sensitivity and specificity in detecting these injuries, aiding comprehensive treatment planning. Conclusion: The study emphasizes the significant association between ACL and meniscal tears, reaffirming MRI’s critical role in precise diagnosis and management. Findings underscore the necessity of concurrent evaluation of ACL and meniscal injuries to optimize outcomes and prevent long-term complications. Future research should explore advanced imaging techniques and preventive measures to address these common knee pathologies.
