Functional outcome of bone patellar tendon bone graft in anterior cruciate ligament reconstruction

Abstract

Anterior cruciate ligament (ACL) tear is the commonest ligamentous injury to the knee joint. Various surgical methods have been described for the anterior cruciate ligament reconstruction with different kinds of grafts which have own merits and demerits. Bone patellar tendon bone is commonly used autograft for ACL reconstruction.Aim of this study was to analyse the functional outcome following arthroscopic ACL reconstruction using Bone- patellar tendon -bone graft (BTB) Materials and methods: This is a prospective study of 32 patients awith the average age of 27 years (range: 19-51 years) between 2017 and 2019. Patients were treated by arthroscpically using bone- patellar tendon- bone graft. Appropriate post-operative care & physiotherapy was given. The functional evaluation of the patients was done at 3 month, 6month & 1year follow up. Based on clinical test we evaluate stability of the knee joint & normal knee function.We also usedTegner Lysholm knee score & VAS score for the evaluation of the results. Results: 93 % of patients had normal or near normal knee function clinically.88% of the patients had excellent score as per Tegner lysholmknee scoring system. 27 out of 32 patient have no pain on VAS score at end of 1 year.The complications observed were anterior knee pain (10%), numbness over graft donor site (8%). Conclusion: ACL reconstruction using the bone-patellar tendon-bone method can provide very good functional outcome based on objective and subjective assessments .Early return to daily activities possible by improving knee stability and knee function.
