[Experimental research on the usefulness of the Dallos polyester prostheses in reconstructive operations of knee joint ligaments].

Usage of allogenic grafts in surgery of severe injuries of knee joint may be necessary in spite of their disadvantages. Prosthesis Dallos made by Tricomed in Lódź has been tested taking into account its usage in reconstruction of knee sacral ligaments. Prosthesis was implanted into 7 piglets in place of the removed front sacral ligament. In the tests the mechanical requirements made for this kind of grafts were confirmed. However, an unfavourable influence of this prosthesis on the synovial membrane of a joint and weak overgrowth of the graft with connective tissue, which can be eliminated by usage of looser knitting, were noticed.
