Purpose: The purpose of this prospective study is to compare the results of arthroscopic reconstruction of ACL using autologous hamstring tendon (Group 1) and autologous bone patella tendon bone (Group 2).
Materials and Methods : From Jan. 2004 to Dec. 2007, fifty patients were analyzed in this study. A single surgeon performed the ACL reconstruction with autologous hamstring tendon (25 patients) and autologous bone patella tendon bone (25 patients) alternatively each other. The mean follow up period of two groups was 38 months (range 25~58 months). We evaluated the result of Lachman test, Pivot shift test as a physical examination and Lysholm score, Tagner activity scale as patients’ satisfaction and functional status and Telometer for anterior instability of each groups at the time of final follow up.
Results: In final results, negative or mild positive findings on Lachman test were 24 out of 25 cases (equally) in each groups. Twenty two cases in the Group 1 and 21 cases in the Group 2 were negative on Pivot shift test. Lysholm scores mark 94.6 points in group 1 and 92.3 points in group 2 at the final follow up and Tegner activity scales mark 8.5 points (Group 1) and 8.1 points (Group 2) at the time of last follow up and there were no differences between the two groups statistically. The numbers of patients who have less than 5 mm of anterior translation of tibia under telometer at 20 degrees of knee flexion are 24 cases in group 1 and 23 cases in group 2.
Conclusion: The overall improvements of clinical scores (Lysholm scores and Tegner Activity scales) of the group 1 were a little bit superior to those of the group 2, but there were no significant statistical difference between two groups.
