[Foreign body synovitis--a limiting factor in use of the Trevira ligament in cruciate ligament surgery?].
In a prospective clinical study on 32 patients with Trevira ligament implants arthroscopic and histological findings were used to assess the articular effects of the synthetic ligament. In group 1 of patients with intact Trevira ligament no changes associated with foreign-body reactions were seen. In group 2 with abrased or frayed synthetic ligaments generalised foreign-body reactions in the suprapatellar recess as well as perivascular, round-cell infiltrates were seen in four out of six patients; four of the six cases also showed fibrotic signs indicative of prearthrotic changes. In group 3 with ruptured Trevira ligament no diffuse foreign-body reactions in the suprapatellar recess were seen in any of the 16 cases. In the intercondylar space foreign-body reactions correlating with the age of the implant were identified (p < 0.03). In 18% of cases with ruptured Trevira ligament generalised foreign-body reactions were seen; however, these changes were not accompanied by chronic inflammatory changes. Cases with technical shortcomings associated with a gradual fraying of the synthetic ligament invariably showed diffuse foreign-body reactions as well as chronic inflammatory infiltrates. In patients with spontaneous ligament rupture due to repeated trauma foreign-body reactions were restricted to the intercondylar space. In spite of the histological evidence of foreign-body granuloma no permanent clinical articular effects could be seen in our patients population within the follow-up time of up to 60 months.
