The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on moasicplasty for knee cartilage defects.

Full thickness cartilage defects of articular surfaces of weight bearing joints these can cause symptoms which vary from severe pain, catching, locking and swelling and may lead to early degenerative changes within the joint.

Mosaicplasty is a technique of creating an osteochondral autograft by harvesting and transplanting many small cylindrical osteochondral plugs from the less weight-bearing periphery of the patellofemoral area and inserting them into drilled tunnels in the defective section of cartilage
