Introduction: Anterior Cruciate Ligament (ACL) reconstruction with hamstring graft is usually done for the surgical management of ACL tear. The post-operative outcome of ACLR is mainly dependant on graft healing its integration into the femoral and tibia tunnels. For the tendon to bone integration it can take up to several months post-surgery. Incorporation of graft into the bony tunnels plays an important role in post-operative outcome after ACL reconstruction surgery. In our study we have aimed to compare hamstring graft healing time post ACL reconstruction when graft was enveloped with periosteum as envelope.
