Introduction: 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.  We kept the knee in the angle of 300, 600   and 900 flexed position and sides were identified and divided into thirteen right and seventeen left. Made an “I” incision on the knee and reflected the skin and ligamentum patellae, the anterior cruciate ligament were observed as anteromedial and posterolateral bundles. The position of angle knee was measured by goniometer and the length and width was measured by digital vernier caliper. The data was presented as frequencies and proportions, mean and standard deviations. Statistical significance (p value) was considered at 0.05 levels.

Results: The mean and standard deviation of anteromedial bundle of anterior cruciate ligament showed in 300 position of knee was 40.3±1.61 and on right side of AMB (n=13) 40.87±1.77 and was in left of AMB (n=17) side of knee 39.86±1, In 600 35.94±2.37 right 36.09±2.61 and left 35.82±2.24, and in 900 position 32.27±2.33 on the right side was 32.25±2.25 on the left 32.28±2.45. Likewise the posterolateral bundle result in 300 positions was 32.07±3.01 on the right side 32.33±3.43 and in left side showed 31.86±2.74, 600 positions of PLB 28.63±2.77 right side 29.23±2.77 and left side 28.18±2.76 and   900 26.07±2.53 right 26.56±2.03 and left side 25.69±2.86. 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.
