Arthroscopical and histological study of cartilaginous lesions treated by mosaicplasty.

Aim: The aim of our study was to assess macro- and microscopically the knee cartilaginous lesions outcome treated by mosaicplasty.

Material And Method: Our study included 32 patients who underwent mosaicplasty for nondegenerative cartilaginous lesions of the knee and a second look arthroscopy. In 21 patients, minibiopsies from the repaired lesion were performed under arthroscopic control (from the cartilaginous region of the transplanted osteocartilaginous grafts and from the spaces between grafts).
