A case of chronic pain postsubtotal meniscectomy after a complex bucket handle tear of the meniscus in a soccer player. (Left) The probe indicates the large size meniscal defect. (Right) This is an arthroscopic view after meniscus transplantation with a cell-free biomaterial. The probe indicates the meniscal defect filling with the cell-free biomaterial. Vascular-forming matrices would improve the integration of the biomaterial and the in-growth of repair cells for regeneration of meniscus tissue.
