Evaluation of anterior cruciate ligament (ACL) reconstruction using autogenous hamstring tendon composite grafts and the modified one incision technique for the revisional ACL reconstruction.

Eight cases that had undertaken revisional ACL reconstruction were evaluated. Follow-up period was 17.5 months on the average (12-41) . All cases were evaluated using the Lysholm knee score, KT-2000 arthrometer (Medmetrics) and one leg hop test.

Lysholm knee score increased from 67.8 to 80.6 by an average of 13 points. When comparing with normal side, the average differences of anterior translation was 2 mm and the average functional activity was 77.1% of the healthy side. All cases returned to the normal activities of daily living.

New femoral and tibial tunnel can be made regardless of pre-existing tunnels with modified one incision technique and hamstring tendon composite graft. Allogeneous bone grafts were used to fill the enlarged tunnels caused by overlapping with pre-constructed tunnels.
