Chondral lesion is common in young adult and may causes persistent joint pain and swelling after medical treatment. The aims of surgical treatment are to restore new cartilage surface. Mosaicplasty is one of the techniques that recommended for a small lesion (less than 2 CM), classified as grade III or IV in International Cartilage Repair Society system. This technique, also known as osteochondral autograft transplantation, harvests the non-weight bearing area of osteochondral part in cylindrical shape usually from the medial femoral condyle and intercondylar notch area and transplant to the defect site. The advantage in knee mosaicplasty are ability to restore hyaline cartilage, single stage procedure and ability to treat subchondral bone involvement lesion.
