[The clinical results of anterior cruciate ligament reconstruction with Intrafix]
1Institute of Sports Medicine, Third Hospital of Peking University, Beijing 100083, China.
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.
