Biologic resurfacing is restoring a damaged joint surface using a biological technique rather than metal or plastic.

Microfracture is a biologic resurfacing technique that picks holes through the damaged area into the underlying bone, allowing bleeding and inflow of pluripotential cells that help to cover the area with new fibrocartilage.
