Arthroscopic ACL Reconstruction with Autologous Hamstring Tendon using Bioabsorbable Cross Pin Fixation on the Femoral Side / 대한정형외과학회잡지

ABSTRACT

PURPOSE: To evaluate clinical results after arthroscopic ACL reconstruction using hamstring autograft with 2 femoral bioabsorbable cross pins fixations. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
