title: [Plastic surgery of the anterior cruciate ligament: experimental study of intra-articular aramid fibers in dogs].
abstract: The authors explored the possibility of replacing an anterior cruciate ligament with an aramid fiber (Kevlar) implant. This study was performed in intra-articular site in 9 dogs and the average implantation period was 5 months. Studies were carried out by macroscopic, photon microscopy, and electron microscopy examination of the samples obtained at the time the animals were sacrificed. Clinical and radiographic studies of the knees were performed in order to assess functional consequences. Overall, the results showed a partial or complete rupture of 10 neoligaments out of the 17 studied ligaments; on the other hand, osseous anchorage and reintegration in the intra-articular zone appeared satisfactory. Kevlar fiber only partially meets the performance specifications for an artificial ligament intended to serve as an anterior cruciate ligament substitute. Some positive results have encouraged the authors to carry on further this experimental study.
