The fate of meniscus cartilage after transplantation of cryopreserved nontissue-antigen-matched allograft. A case report.

A cryopreserved nontissue-antigen-matched meniscus was transplanted in the knee of a 48-year-old man with lateral compartment osteoarthrosis. After six months, diagnostic arthroscopy was performed. Clinical, histologic, and histochemical studies showed that meniscal chondrocytes survived cryopreservation and transplantation. One year after surgery, the outline of the donor meniscus on an arthrogram appeared normal.
