Comparative Analysis of the Functional Outcome of Arthroscopic Anterior Cruciate Ligament Reconstruction Using Quadrupled Hamstring Graft Fixed With Bio Absorbable Interference Screw Against Titanium Interference Screw

Abstract

Anterior cruciate ligament injury is one of the most common injuries around knee and poses quiet a lot management controversies. Anterior cruciate ligament has a pivot role in function and stability of the knee joint along with all other ligaments, being a prime stabilizer preventing the anterior translation of tibia over femur. Acute anterior cruciate ligament injury causes recurrent episodes of instability, pain and decreased motion. Anterior cruciate ligament reconstruction allows return to pre injury levels even in athletes, delays development of early osteoarthritis and reestablish the stability of the joint. Graft fixation during ACL reconstruction can be achieved with use of either metal screws or bio absorbable screws. Bio absorbable screws usage provide better visibility in postoperative MRI and also avoid removal at later stage. However there are controversies regarding the ideal graft, ideal fixation device, ideal time and technique of reconstruction. In this study we have compared the metal and bio absorbable screw for fixing the graft and reported the result.
