Correlation between Anterolateral Ligament and Anterior Cruciate Ligament Tears-MRI Study
Journal Title: International Journal of Anatomy Radiology and Surgery - Year 2018, Vol 7, Issue 4
Abstract
Introduction: Various, very well established ligaments and menisci form the framework of stability to the knee and all these structures are already being clearly evaluated on an MRI examination. The Anterolateral Ligament (ALL) however is a relatively newly described structure in the knee which is causing a lot of anticipation for its role in rotational stability. Aim: The present study was done with the aim of identifying tears of the anterolateral ligament, classifying them according to the involved segment and to assess the segment wise association of tears of Anterior cruciate ligament (ACL) with Anterolateral Ligament (ALL). Materials and Methods: A study population of 125 patients presenting with post traumatic knee instability were studied for a period of one year and one month. A 1.5T MRI was used for the study with dedicated high resolution sequences. The results were analysed by calculating the number of patients with ALL tears and by analysing how many of these had a segment wise associated tear of the ACL. Results: The results were analysed by calculating the number of patients with ALL tears and by analysing how many of these had a segment wise associated tear of the ACL. Among the study population, 68 (54.40%) participants had a tear of the ACL at its femoral attachment, 24 (19.20%) participants had a mid segment ACL tear and 14 (11.20%) participants had tear of the tibial insertion of the ACL. Among the study population, 47 (37.60%) participants had a tear of the femoral attachment of ALL, 7 (5.60%) had a tear of the meniscal segment of ALL and 8 (6.40%) participants had a tear of the tibial attachment of ALL. Majority of the patients with femoral and tibial attachment tears of the ALL had a corresponding segment tear of the ACL. Conclusion: A strong, segment wise association of tears of ACL and ALL was established by this study when it came to tears involving their femoral attachments and the tibial attachments, thereby ascertaining a causal factor of both ligaments in rotational stability of knee. It is essential that the integrity of ALL is established before an ACL reconstruction.
