This  study was conducted to evalvate the Functional Outcome Of Arthroscopic Reconstruction using fourfold hamstring autograft in persons with ACLtear.

METHOD:–This study is a prospective study conducted in our hospital. Total 27 patients with clinical/radiological/arthroscopic evidence of ACL deficiency were treated with fourfold hamstring graft and evaluated immediate postop  with clinical test & compared with preop clinical test grading. The postop results at 6 month follow up evaluated with using IKDC & LYSHOLM score.

RESULTS;– The results for manual knee laxity test were evaluated statistically before & after ACL reconstruction , using the paired T test at 5% level of significance, the results were found to be significant. The results of the mean of pre operative Lachman test was 2.86 + 0.36 SD and post operative lachman test has mean 0.55 + 0.75 SD with significant p value 0.001,similarly the mean preoperative Pivot Shift Test(PST) was 2.03 + 0.70 SD and post operative was 0.22 + 0.50 with significant p value < 0.001 .  Results of ACL reconstruction after 6 months of follow up were evaluated and showed excellent results in 7(25.9%) cases, good results in 15(55.5%) cases, fair results in 4(14.8%) cases and poor results in 1(3.7%) cases, according to Lysholm score. Mean Lysholm score postoperatively was 88.37. The mean subjective IKDC after 6 month follow up was 82.16. 85.5% (23) cases of isolated ACL tear had normal and near normal knee, according to IKDC scoring system..only 1 case  had graft failure due to migration of endobutton in femoral tunnel.

CONCLUSION;– This subjective study suggesting that ACL reconstruction with quadrupled hamstring graft fixed with endobutton in the femoral tunnel and bio– interference screw in the tibia is a reliable, effective and reproducible technique but more quantitative and long term studies are required.
