[Arthroplasty using Mosaicplasty].

Abstract

Mosaicplasty is a method to repair the chondral defect of the weight-bearing surface by transplanting the cylindrical osteochondral plugs harvested from the non-weight bearing surface of the knee. The chondral defect is repaired with a complex of the transplanted hyaline cartilage and the regenerated fibrous cartilage in between. It can be performed arthroscopically and the postoperative rehabilitation can be started earlier, but the number of the harvested plugs is limited. The indication of mosaicplasty is the medium-sized focal chondral defect under the age of 50. Usually, osteoarthritis can not be indicated, but can be performed for the early stage of osteoarthritis and osteonecrosis in combination with osteotomy.
