To evaluate the correlation between bone tunnel diameter following Anterior cruciate ligament (ACL) reconstruction measured by computed tomography (CT) using multiplanar reconstruction (MPR) and functional outcome.
Materials and methods: This study is a prospective study. Fifteen patients (14 men and 1 women, with mean age 30.27 years) who had undergone ACL reconstruction with hamstring tendon auto graft had subsequent CT scan during their follow up (mean follow up is 11.27 months) were included in this study.
The diameter of both tunnels (femoral and tibial) were measured using MPR (multiplanar reconstruction) technique. Functional outcome was evaluated with International Knee Documentation Committee grade. Statistical analysis of the correlation between the diameter of the tunnels and IKDC grade were investigated.
Results: The tibial and femoral bone tunnels were found to be significantly widened. There was no significant correlation between the diameter of bone tunnels and functional outcome (IKDC grade).
Conclusion: Neither the diameter nor its widening during interval follow-up is correlated with functional outcome (IKDC Grade).
