Femoral head mosaicplasty by direct anterior approach for an osteochondral impaction without performing surgical hip dislocation.

Several surgical methods exist for the treatment of osteochondral lesions of the femoral head. They include osteochondral allograft transfer, femoral osteotomy, microfracture, autologous chondrocyte implantation, and hip arthroplasty. Mosaicplasty is a surgical method in which cylindrical plugs of bone and cartilage are transferred from a donor site to tunnels drilled into the bone and cartilage defects.
