Purpose: To evaluate status of reconstructed ACL and changes around graft through second-look arthroscopy after arthroscopic reconstruction of the ACL with autograft tendons. Material and Methods: Between Jun. 2003 and Feb. 2007, the second look arthroscopy was performed on 22 cases. Second-look arthroscopy was conducted on average 15.1 $(7\sim31)$ months after reconstruction. 15 cases received hamstring tendon autograft, 7 cases received bone-patellar tendonbone autograft. We measured graft tension using displacement by probing, synovial coverage by visual analysis at second-look arthroscopy The assay in Lysholm score, Lachmann test and KT-2000 arthrometer were evaluated status of reconstructed ACL. Results: The hamstring tendon group showed normal tension in 11 cases and lax tension in 4 cases. The patellar tendon group showed normal tension in 3 cases, lax tension in 2 cases and partial tear in 2 cases. In the hamstring tendon group, synovial coverage was good in 11 cases, half in 3 cases and pale in 1 case, and the bone-patellar tendon-bone group was good in 4 cases and half in 3 cases. The patellar tendon group was superior to the hamstring tendon group in Lysholm score (p<0.05), but insignificance difference in KT-2000 arthrometer results statistically. Conclusion: The hamstring tendon group was superior to the bone-patellar tendon-bone group in second-look arthroscopy after ACL reconstruction with autograft tendons results, but long term follow up will be necessary to further evaluated.
