A study on functional outcome of arthroscopic anatomical reconstruction of anterior cruciate ligament using quadrupled hamstring graft
Keywords:Anterior cruciate ligament, Arthroscopic anatomical reconstruction, Biointerference screw
Background: Various techniques and graft types are now available for the reconstruction of ACL. Opinions differ among experts with regard to the ideal technique and graft type to be used. Arthroscopic anatomical ACL reconstruction using quadrupled hamstring autograft with fixation in the femoral tunnel using tightrope and in the tibial tunnel with interference screw is a relatively new technique. Purpose of this study is to analyze the postoperative outcome in our experience with this procedure.
Methods: This was a prospective study of patients with ACL injury who underwent Arthroscopic anatomical ACL reconstruction using quadrupled hamstrings autograft. All patients were operated upon by the same surgeon and had the same rehabilitation protocol. They were followed up for six months at regular intervals using IKDC, LGS scoring systems, tegner activity scale and a subjective questionnaire.
Results: About 95% of the patients had a favorable outcome as per three scoring systems. (IKDC, Lysholm score, subjective questionnaire) all three scoring system had a very high correlation around 90% of individuals were able to return to their pre injury activity level.
Conclusions: We conclude that the functional outcome of arthroscopic anatomical anterior cruciate ligament reconstruction using quadrupled hamstrings tendon autograft is excellent to good (95%). With proper patient selection and rehabilitation full occupational and recreational activities can be expected for most of the patients within four to six months of the procedure.
