Background: ACL injuries result in persistent recurrent instability and increased risk of meniscal tears and intra-articular damage, leading on to degenerative changes in the knee. There are many studies about ACL reconstruction using bone patellar tendon bone graft (BPTB) and its outcome, but there is not enough literature on the subjective assessment following reconstruction. We decided to do a study of the patient’s subjective outcome as per the International knee documentation committee score (IKDC) and other clinical parameters following ACL reconstruction using the BPTB graft.

Methods: This was a prospective study consisting of 50 patients who presented with ACL injury and underwent arthroscopic ACL reconstruction using BPTB graft in our hospital in the period from May 2008 to July 2010.  Patients were followed at regular intervals at 4 weeks, 8 weeks, 3 months & 6 months and 1 year. Patients were assessed at every visit with clinical tests and IKDC subjective assessment score.

Results: 50 patients with ACL insufficiency underwent ACL reconstruction. Postoperative knee flexion improved; the mean flexion was 131.70 with standard deviation of 6.534, which was significant. The mean preoperative IKDC was 56.97 and standard deviation of 9.188 and postoperative IKDC score was 92.33 and standard deviation 5.198 which showed a marked improvement and was statistically significant. The complications included; 8 patents with anterior knee pain, 1 case of patellar fracture while harvesting graft, which healed with wiring and 2 patients, had re-rupture of ACL due to road traffic accident.

Conclusions: ACL reconstruction with BPTB graft showed a significantly good subjective outcome on assessment using IKDC score. Isolated ACL reconstruction showed a better subjective outcome compared to the patients who had associated meniscal injury.
