Abstract: Aims & Objectives:
To assess the accuracy of preoperative measurement of Hamstring graft thickness using Magnetic Resonance Imaging (MRI) with intra-operative measurements.
Materials: The present prospective type of clinical study was conducted. A total of 50 patients operated for Anterior Cruciate Ligament (ACL) reconstruction were selected for the study. Informed consent was obtained from all study participants. Patients who fulfilled the inclusion criteria were studied and evaluated.
Results and Observations: It was observed that the maximum number of patients (56%) belonged to age group 21-30 years. The mean ± standard deviation of age was 31.04±6.58. It was observed that 72% of patients were males and 28% females, the mean ± standard deviation of anteroposterior (AP) and mediolateral (ML) diameter of semitendinosis on Magnetic Resonance Imaging at joint line was 6.34±0.88 and 6.57±0.71 respectively. The anteroposterior and mediolateral diameter of semitendinosis on Magnetic Resonance Imaging at physeal line was 6.71±0.61 and 6.99±0.39 respectively. It was observed that the measured values on Magnetic Resonance Imaging at joint level and physeal level correlated with the intraoperative values of semitendinosis graft and p value was significant. (p value<0.05).
Conclusion: A significant statistical correlation was found between the diameter of the 4-stranded semitendinosis autograft and mediolateral diameter and the anteroposterior diameter at both levels.
