Purpose: To investigate the causes of failure on ACL reconstructions and evaluate the effectiveness of one stage revision ACL reconstructions.
Materials and Methods: From November 2004 to July 2008, thirty three patients who had got revision ACL recontstructions after reruptures of ACL were evaluated. The causes of failure of ACL reruptures were 22 vertical femoral tunnels, 7 neglected PLRI, 3 severe traumas and 1 deep infection after ACL reconstruction. The femoral tunnels were aimed at the 10 or 2 o’clock position and the tibial tunnels were used with previous tunnels. Previous femoral screws from the improper femoral tunnels were removed and filled with the new allograft bones.
Results: The average periods of follow up were 22.2 months (12~52 months). There was improvement on an average Lysholm knee score from 61.5±16.8 to 86.3±11.5, IKDC score from 63.9±15.1 to 81.3±14.3. Mean side to side difference was decreased from 6.0±2.2 mm to 1.6±1.4 mm using KT-2000 arthrometer.
Conclusion: One stage revision ACL reconstruction can be a useful method with good clinical results.
