Purpose: We wanted to evaluate the clinical results of ACL reconstructions with using four strands of an auto-hamstring tendon graft and a bioresorbable-Transfix device (Arthrex, Naples, FL) for femoral fixation.
Materials and Methods : From May 2005 to May 2007, a total of 108 cases that underwent arthroscopic ACL reconstruction with using hamstring tendons and a bioresorbable-Transfix device were followed-up for more than 1 year (Range: 12~32 months) postoperatively. The clinical results were evaluated by the preoperative and postoperative Lysholm knee scores, the International Knee Documentation Committee (IKDC) scoring system and a KT-1000 arthrometer. The radiological results were evaluated by the measurement method described by L`Insalata.
Results: Preoperatively, the mean Lysholm knee score was 70.8±6.8 (Range: 52.0~81.0) which improved to 94.2±4.8 (Range: 76.0~98.0) at the last follow up (p＜0.05). According to the IKDC scoring system, 104 cases (96%) were categorized as normal or nearly normal and no case was categorized as severely abnormal at the last follow up (p＜0.05). KT-1000 arthrometer instability was statistically improved from 8.8 mm (Range: 3~17 mm) to 2.1 mm (Range: 1~7 mm) (p＜0.05). The femoral and tibial tunnels were statistically widened 22.7% and 12.7% on the AP view, respectively, and 17.4% and 8.4% on the lateral view, respectively, at the last follow up (p＜0.05).
Conclusion: ACL reconstruction using auto-hamstring tendons with a bioresorbable-Transfix device showed satisfactory results on the physical examination and functional evaluation.
