Abstract

PURPOSE: We report the result of arthroscopic ACL reconstruction using a bone-patellar tendon-bone allograft with the Flip technique.
MATERIALS AND METHODS
From October 2002 to August 2003, 21 cases of arthroscopic ACL reconstruction were performed using the Flip technique. The average age and follow-up period was 29.3 years old (17-46) and 13.7 months (10-20), respectively. Physical examinations, such as Lachman test, pivot shift test and measured a quantitative KT-2000 testing, the Lysholm, IKDC, and Tegner scores were performed and the results were compared with those of the final evaluation.
RESULTS
Final results of the Lachman test were 1+ in 9 patients, 2+ in 1 patient, and the pivot shift was positive in only 1 patient. Preoperative evaluation revealed an average score with a KT-2000 of 6.8 mm, a Lysholm score of 50.4, an IKDC score below C in all cases and a Tegner score of 3.0. However, the final results showed a KT-2000 of 3.2 mm, a Lysholm score of 86.2, an IKDC score above B in all cases and a Tegner score of 6.6.
CONCLUSION
Arthroscopic ACL reconstruction using allogeneic bone-patellar tendon-bone graft with the Flip technique showed excellent functional results with a resolution of the graft-tunnel length mismatch.
