The location of femoral and tibial tunnels in males and females after anterior cruciate ligament reconstruction and its correlation with the functional outcome
Objective: The purpose of this study was to visualize and quantify the position of bone tunnels in anterior cruciate ligament reconstruction with use of novel methods applied to three-dimensional computed tomographic reconstruction images and its impact on functional outcome post-operatively.
Methods: This is a prospective cohort study of 50 patients of ACL tear injury. Patient who were operated for ACL reconstruction were followed up for 6 months and post-operative status assessed based on Tegner and Lysholm scoring, three dimensional CT scan of the operated knee to decide tunnel placement.
Results: In our study, out of 50 patients enrolled, 35 were males and 15 were females which shows ACL injury is almost twice more common in males than females. Age of the patients ranged from 23 years to 42 years, average age being, 30 years. Thus proving ACL injury is more common in younger and active age group. Out of 50 patients, 40 had improvement as compared to pre-op status whereas 10 patients had complaint of persistent symptoms post-operatively.
Conclusion: ACL tear is more common in males as compared to females and young, active people are affected commonly. Tunnel placement plays an important role in post-operative rehabilitation of the patients but it’s not the only factor playing role.
