Cartilage Bone Transplantation

Illustration 5 • Multiple transplantations (mosaicplasty)

This procedure harvests cylindrical cartilage bone transplants from a peripheral non damaged area of the joint, which are then pressed fit into the prepared, damaged area.

If several punches are used, the cartilage damage is filled in mosaic-like fashion. Within one year, the damaged area is filled with fibrous cartilage and levels with the surrounding cartilage.

The longest post-op study lasted for six years. A tissue sample taken after this period of time showed 80% of excellent, resilient cartilage in the transplanted area. Deep and extensive cartilage damage should not be treated with this method, mainly because of the limited availability of autologous material for transplantation.
