초록

The aim of this study was to evaluate the post-operative outcomes of anterior cruciate ligament (ACL) reconstructionuction using 2 additional fixation technique on tibial side(bioabsorbable suture anchor and metal screw fixation). Between Oct 2008 and Feb 2012, sixty consecutive patients who underwent ACL reconstruction with allograft for ACL injuries were retrospectively enrolled. All patients were reconstructed with fresh frozen achilles tendon or posterior tibialis tendon allograft. Fixation on tibial side with bioabsorbable suture anchor(BSA) was in 30 patients(Group A) and metal screw fixation was in 30 patients(Group B). The data was collected at preoperatively and at least 1 years post-operatively, which included KT-2000 arthrometer objectively, and Tegner score, Lysholm score, and International Knee Documentation Committee(IKDC) scores subjectively. At the final follow up, the KT-2000 arthrometer improved significantly with an average of 3.28 mm anterior translation in the group A, 3.56 mm in group B. The preoperative mean Lysholm and Tegner score was 46.14, 4.86 in the group A, and 45.30, 4.40 in the group B. The postoperative mean Lysholm and Tegner score was 83.80, 8.14 in the group A, and 88.75, 7.62 in the group B. The initial preoperative mean IKDC was 63.17 in the group A, 54.07 in the group B. The final mean IKDC was 75.57 in the group A, 65.10 in the group B. All functional outcomes were improved significantly (p=0.004) in both groups, but no differences were noted between the 2 groups (p>0.05). Both additional fixation techniques using BSA or metal screw fixation on tibial side in ACL reconstruction improved functional outcomes significantly. BSA technique seems to provide adequate strength suitable for early rehabilitation after ACL reconstruction
