We report the result of arthroscopic ACL reconstruction using a bone-patellar tendon-bone allograft with the Flip technique.

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.

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.

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.
