The successful treatment of chondral and osteochondral defects of the weightbearing surfaces is a challenge for orthopaedic surgeons. Autologous osteochondral transplantation is one method that can be used to create a hyaline or hyaline-like repair in the defect area. Ten years of clinical experience with autologous osteochondral mosaicplasty are described. Clinical scores, imaging techniques, arthroscopy, histological examination of biopsy samples, and cartilage stiffness measurements were used to evaluate the clinical outcomes and quality of the transplanted cartilage in a total of 831 patients who underwent mosaicplasty. According to our investigations, good-to-excellent results were achieved in 92% of the patients treated with femoral condylar implantations, in 87% of those treated with tibial resurfacing, in 79% of those treated with patellar and/or trochlear mosaicplasties, and in 94% of those treated with talar procedures. Long-term donor-site disturbances, which were assessed using the Bandi score, showed that patients had 3% morbidity after mosaicplasty. Sixty-nine of 83 patients who were followed arthroscopically showed congruent gliding surfaces, histological evidence of the survival of the transplanted hyaline cartilage, and fibrocartilage filling of the donor sites. Four deep infections and 36 painful postoperative hemarthroses were experienced as complications arising from the surgical procedures. On the basis of both these promising results and also those of other similar studies, autologous osteochondral mosaicplasty would appears to be an alternative for the treatment of small and medium-sized focal chondral and osteochondral defects of the weightbearing surfaces of the knee and other weightbearing synovial joints.
