Abstract
Mosaicplasty involves the transplantation of one or more cylindrical plugs harvested from less weight-bearing periphery of the articular surface of the femoral condyle. The procedure can be done open or arthroscopically; however, it is crucial to maintain a perpendicular graft orientation and match the articular surface contour. Plugs should also be matched to the depth of the recipient site. Multiple clinical studies have demonstrated good-to-excellent results in short- to midterm follow-up. Positive prognostic factors include smaller lesion size, shorter preoperative duration of symptoms, no prior surgical treatment, younger patient age, and a higher preinjury level of sports. Imaging studies and second-look arthroscopy have also confirmed good integration and maintenance of grafted cartilage. However, patients must be counseled on potential complications including fibrous overgrowth, graft subsidence, chondrocyte death, deep venous thrombosis, intra-articular bleeding, and infection.
