If it is necessary to remove the entire damaged meniscus, the graft is a meniscus obtained from a deceased donor from a tissue bank (the so-called allograft). When only part of the meniscus is damaged, in some cases it is possible to implant a synthetic implant. The implant is biodegradable and gradually overgrows with natural fibrous tissue, replacing the missing part of the meniscus. The procedure of implanting an allograft or a synthetic fragment of the meniscus is performed as part of a minimally invasive arthroscopy / link / procedure without the need to open the joint.
