Two methods for the plastic reconstruction of degenerative Achilles tendon ruptures have been developed, using biological xenopericardium prosthetics. 21 patients were operated. In cases of tendon gliding surface deformation, the insulating plastic reconstruction was used in 14 of them by wrapping the suture area with xenopericardium; the replacement plastic reconstruction was applied in 7 patients. In case of an unrecoverable defect, the tendons were replaced with a specially formed prosthesis. The long-term results of the use of xenopericardium prostheses were compared with the traditional methods. The study involved 120 patients, divided into 5 groups according to the type of surgery: the closed perirocous suture of the Achilles tendon (25 patients), the open stitching of the ruptured tendon (28 patients), the plastic tendon by Chernavsky (24 patients), the tendon plastics by the lavsan ribbon (22 patients) and the tendon grafting with xenopericardium bioprostheses (21 patients). The results were evaluated by the method of Leppilahti J. (1998). The results obtained suggest that the application of xenopericardial prosthetics leads to a significant increase in the number of excellent and good results in comparison with the other methods.
