[Reconstruction of the anterior cruciate ligament with artificial ligament (Ligastic). Clinical results in 72 patients].

INTRODUCTION
The purpose of the study was to evaluate the anatomical and functional results of Anterior Cruciate Ligament reconstruction with the synthetic ligament Ligastic.


MATERIAL AND METHODS
72 patients have been reviewed clinically and radiologically and their functional abilities have been evaluated with Lysholm and Arpege score. 46 have been operated for recent ruptures (group A) and 26 for chronic ACL tears (group B). Follow up was 2 to 4,5 years.


RESULTS
The results showed in group A a Lachman test > 3 mm in 57 per cent cases, a positive pivot shift in 29 per cent and ruptures of the ligament in 22 per cent. In group B, the Lachman test was > 3 mm in 47 per cent of the cases the pivot shift was positive in 54 per cent and the rupture of the ligament occurred in 35 per cent. The functional evaluation showed that only one third was stable but painful, and one third was unstable and painful.


DISCUSSION
As many authors, we found an increase of bad anatomical and functional results with time. The ligament can't be considered as a scaffold for ingrowth tissue. Two thirds of the patients had painful knees at effort.


CONCLUSION
The high percentage of ruptures of the ligament, and the non satisfactory functional results led us not to recommend the ACL reconstruction with a Ligastic implant.
