[MR tomography in autologous plastic repair of the anterior cruciate ligament: a comparison of 2 surgical methods].
The aim of this prospective MRI study was the analysis of the post-operative signals derived from two techniques for cruciate ligament reconstruction.


METHODS
Group 1 consisted of 15 patients who had undergone conventional plastic repair by patellar tendon transplant and group 2 was made up of 15 patients with arthroscopic reconstruction with semitendinosus grafts. They were examined at 6 weeks and 6 months post-operatively.


RESULTS
Typical appearances of normal transplants were found in 19 patients. After 6 months 8 of the patellar tendon transplants and three of the semitendinosus transplants could not be clearly defined. At this time there was a significant increase in signal intensity in the middle third of the transplant in group 1.


CONCLUSIONS
Bearing in mind the different operative techniques, there was a higher impingement rate in group 1. The post-operative MRI findings at 6 months after surgery allowed differentiation between pathological changes (impingement) and revascularisation (remodelling).
