To evaluate clinical results after arthroscopic ACL reconstruction using hamstring autograft with 2 femoral bioabsorbable cross pins fixations.

We evaluated the results of 97 knees in 97 patients who had arthroscopic ACL reconstruction using hamstring autograft fixed with 2 femoral bioabsorbable cross pins from September 2001 to September 2002. Average follow up was 21.9 months (range: 18-32 months). Patients were evaluated by KT 1000 arthrometer test, Lysholm score, IDKC score at preoperative and follow-up examination. Second-look arthroscopy was performed in 49 knees.

Average Lysholm score was 72.3 (range: 51-83) preoperatively and 93.1 (range: 71-99) postoperatively. At final IKDC evaluation, 59 knees were normal (A), 36 knees nearly normal (B), 2 knees abnormal (C), and severe abnormal (D) none. Mean side-to-side difference on maximum manual evaluation using KT-1000 was at 1.3 mm (range: 1-6 mm) at follow-up. 49 knees underwent arthroscopic 2nd look evaluation, of which 31 knees preserved good tension, 18 knees some laxity, graft failure or rupture is none.

ACL reconstruction using four strands hamstring autograft fixed with 2 bioabsorbable cross pins on the femoral side showed good stability in 97.9% patients at mean 21.9 months follow-up, and can be considered clinically safe and useful method.
