The Morphometric Study of Anterior Cruciate Ligament: A Cadaveric Study

Abstract

The anterior cruciate ligament is frequently injured ligament of the knee. It divides into anteromedial and posterolateral budles attached into tibia and femur. This study aimed to measure the length and width of two bundles of ACL separately to observe the morphormetrical difference. Since single or double bundle ACL reconstructive surgical procedure are commonly used by orthopaedic surgeon, our study may help them in hamstring or tendon graft procedures. Material and Methods:The Cadaveric study was conducted in the department of Anatomy at Pondicherry institute of Medical sciences, Pondicherry from December 2015 -May 2016. Randomly selected thirty cadaveric was included for the study and knees with ACL tear; macroscopic degenerative changes or any evidence of trauma was excluded from the study. The data was presented as frequencies and proportions, mean and standard deviations. Statistical significance (p value) was considered at 0.05 levels.Results: There was a statistically significant increase in transverse diameter. We observed P value of transverse diameter of anteromedial bundle at tibial attchment (0.01) and (0.05) in anteroposterior diameter of posterolateral at tibial and in middle (0.04) showed a statistically significant increase in transverse diameter. Conclusion:ACL tears are managed surgically by a double bundle or single bundle ACL reconstruction technique. Recently, the anatomic double bundle ACL reconstruction has been found to be better in restoring the intact knee function compared to the conventional single bundle surgery when done perfectly. So our study of morphometric measurements of ACL can help the surgeons during accurate tendon graft procedure of anterior cruciate ligament reconstructive surgeries.
