Short term functional outcome following arthroscopic ACL reconstruction using a combination of quadruple hamstring tendon, adjustable cortical suspensory fixation device on femoral side and bio-screw on tibial side

Abstract

Background: The Anterior Cruciate ligament (ACL) is the most commonly injured ligament among the sports persons. The success of Anterior cruciate ligament (ACL) reconstruction requires ideal graft, reliable and rigid graft fixation and well planned rehabilitation protocol to bring them back to their pre injury state of function. Hamstring graft in place of Bone Patellar Tendon Bone Graft has revolutionized the ACL surgery all over the world with Good to Excellent functional outcomes with negligible anterior knee pain. Cortical suspensory fixation (CSF) devices have become an acceptable alternative to interference screws for Hamstring tendon grafts on Femoral side and a Bio-screw fixation on tibial side. Aim: Short term Functional Outcome Following Arthroscopic ACL Reconstruction in Non-Athletic patients using a combination of Quadruple Hamstring Tendon, Adjustable Cortical Suspensory Fixation Device on Femoral side and Bio-Screw on tibial side. Materials & methods: The retrospective data of 32 knees (31 patients), who have undergone ACL reconstruction between April 2011 to March 2019 using AM Portal with quadrupled Hamstring tendon graft, adjustable CSF Device on femoral side and Bio-absorbable interference screw on tibial side were included. All the patients were followed up to a minimum period of one year and maximum period of 2 years post ACL reconstruction. The knee function was assessed by using Tegner Lysholm knee scoring scale. Results: In our study of 32 knees in 31 patients, the average age of the patients was 30.70 years. Good to excellant functional outcome was achieved in 94% of patients and fair functional outcome was present in 6% of patients by Tegner Lysholm knee score. There was significant improvement in Post ACL reconstruction mean score (89) from Pre-Operative mean score (49) using Tegner Lysholm knee scoring scale. Conclusions: The short-term results of Arthroscopic ACL reconstruction with a combination of quadrupled Hamstring tendon graft, femoral adjustable CSF device and Bio-absorbable interference screw fixation on tibial side using AM Portal gives good to excellent functional outcome in Non-athletic patients. However, we recommend a larger cohort and longer study period to validate the results and conclude further.
