RETROSPECTIVE PROSPECTIVE COMPARATIVE ANALYSIS OF RECONSTRUCTION OF ACL TEAR WITH QUADRUPLED HAMSTRING GRAFT VERSUS QUADRUPLED HAMSTRING GRAFT INTERNALLY BRACED WITH FIBERTAPE

Background: Reconstruction of anterior cruciate ligament is a widely done surgery. The surgical outcome is dependent upon the strength of the graft used. Quadrupled hamstring graft is a commonly used graft as it provides good strength and functional outcomes. However graft re-rupture and laxity of the graftare amongst the known complications which lead to repeat surgeries and unsatisfactory outcomes. Various techniques have been described to strenghthen the graft. This study compares the cumulative effect of internally bracing quadrupled hamstring graft using fibertape with quadrupled hamstring graft alone in terms of functional outcome and laxity.

Materials and Method:The study was done at the Department of Orthopaedics at King Georges Medical University in Lucknow on 60 patients with anterior cruciate ligament tears from October 2021 to October 2022. The patients were divided into two groups: Group 1 had quadrupled hamstring graft reconstruction done alone, and Group 2 had quadrupled hamstring graft reconstruction done with fibertapebracedinternally.Lysholm knee score was used as a measure of functional outcome along with standardized Pivot shift test, Lachman testand anterior drawer test to measure and compare the pre- and postoperative variation in laxity.

Results:On comparing the improvement in grades at subsequent follow-up, group 2 showed significant improvement in functional outcomes in terms of Lysholm knee score .

Conclusion:We concluded that reconstruction of anterior cruciate ligament using quadrupled hamstring graft internally braced with fiber tape gives a better functional outcome in form of Lysholm knee score although there was no significant improvement in grades of Anterior Drawer and Lachman test. Although follow up period of six months was a limiting factor . Further clinical evaluation over a longer period of follow up to evaluate the effect of fibertape on shielding and creeping of graft is essential and also to study the resultant collagen fibretapes clinical behavior.
