[The clinical results of anterior cruciate ligament reconstruction with Intrafix].

OBJECTIVE

To investigate the clinical results of anterior cruciate ligament (ACL) reconstruction with Intrafix.

METHODS

From March to December in 2005, there were 35 patients with ACL rupture using quadruple semitendinosus and gracillis. Endobutton was used to fix the graft at the femoral site. Thirty-two cases were followed up at the average time of 15 months (12-20 months). In 15 patients the subjective knee function evaluation, KT-2000 and X ray were performed, and MRI was performed in 11 cases either. Other 17 cases had only the subjective knee function score.

RESULTS

The average IKDC score was 91 (83-97). In 15 cases there were 10 cases whose knee examination results of IKDC were A grade, 5 cases B grade (because of limited range of motion). Lysholm scores were average 89 (83-93), 17 cases excellent and 15 cases good. The results of KT-2000 were average 1.2 mm (0-2.0 mm) at 30 degree 133 N, average 0.5 mm (-0.5-2.0 mm) at 90 degree 133 N. The appearance and tension of reconstructed ACL were good on MRI. The X ray showed good position of bone tunnel.

CONCLUSION

ACL reconstruction with Intrafix can restore the stability of knee, and the clinical result is good.
