Abstract: Background: Knee injuries are more common due to exponential increase in road traffic accidents and more involvement in sports related activities by common people. Anterior cruciate ligament injury is one of the most common injuries around knee and poses quiet a lot management controversy.
Aims and Objectives: To do comparative analysis of the functional outcome of Arthroscopic Anterior Cruciate Ligament Reconstruction using quadrupled semitendinosus and gracilis graft with endobutton as femoral fixation device and bioabsorbable interference screw against titanium interference screw as tibial fixation devices respectively.
Materials and Methods: 60 Patients with ACL tear attending out patient department of a tertiary care hospital were recruited in this prospective, comparative study. Detailed proforma consisting of patient information, Lysholm and Gillquist scoring scale were administered pre and postoperatively for patient. The difference in clinical outcome of both groups was compared. Out of 60 patients 30 patients underwent ACL reconstruction using Titanium screw and 30 patients underwent ACL reconstruction using Bioabsorbable screw. All patients were followed up for a period of 6 months post operatively. Improvement in patient condition was measured in terms of improved Knee range of motion, walking with or without support, any instability, any locking of knee, any pain while activity.
Results: Mean preoperative Lysholm score for Titanium group was 52.60 and postoperative score is 85.56. Mean preoperative Lysholm score for Bioabsorbable Group is 54.70 mean postoperative score for group is 87.63. The increase in both scores was statistically significant when compared within the groups. And when both groups are compared, there was no significant difference between 2 groups. Few of our patients presented with anterior knee pain in immediate post-operative period which subsided with physiotherapy and medication, none of them had chronic knee pain.
Conclusion: Our study shows that there is no difference in functional outcome whether bioabsorbable or titanium interference screw was used.
