To study the clinical and functional outcome of single bundle arthroscopic ACL reconstruction using autologus hamstring tendon graft

Abstract

Objective: To study the clinical and functional outcome of single bundle arthroscopic ACL reconstruction using autologous hamstring tendon graft.

Methods: A randomised prospective trial was conducted in 40 patients of ACL tear, in the age group 20-45 years. After selection of the patients, pre-operative clinical scoring was done. All patients were taken for single bundle ACL reconstruction using autogenous hamstring quadrupled graft fixing with adjustable loop and bio-interference screw. Preoperative and postoperative Clinical assessment was done by using Lysholm Gillquist score and IKDC score.

Results: It was observed that the mean Lysholm score at pre-operatively was 79.38 ± 11.32. At 2 weeks the Lysholm score declined to 39.00 ± 5.93 and then it gradually increased to 89.62 ± 8.90 at 24 weeks. Further, it was observed that there was a significant mean difference in lysholm score across various time points (p value of <0.001). The mean IKDC score at pre-operatively was 56.70 ± 12.27. At 2 weeks the IKDC score declined to 33.03 ± 4.22 and then gradually increased to 88.99 ± 6.50 at 24 weeks.

Conclusion: Single bundle arthroscopic ACL reconstruction using autologous hamstring tendon graft provides a good functional result in young active adults. Arthroscopic ACL reconstruction using adjustable loop endobutton and bio-absorbable interference screw at tibial end gives excellent result with minor complications.
