Artificial meniscal lesions extending into the avascular part of the meniscus,
which do not heal by any other means, were repaired by suturing either a porous
polymer implant or a synovial flap into the defect. The implant guided the
ingrowth of vascular repair tissue into the defect. This fibrous tissue later on
transformed into fibrocartilage. Reconstruction with a synovial flap was not
successful. It appeared that healing can be achieved by implantation of a porous
polymer implant in a large number of cases. Future research will be aiming at
improvement of the results of meniscal repair and application of this type of
polymer for repair of cartilage defects.
