Fig. 21.19 (a) Model of a semi-circular cartilaginous disk (Meniscus) that resides in the knee joint, (b) Molded bacterial cellulose meniscus. (c) Implantation of the construct into a created meniscal lesion in vivo. The traction sutures are visible on the outer third of the meniscus. The seeded implant (Arrow 1) is inserted into the created meniscal lesion with an Adson forcep. The insertion of the implant is facilitated by the use of a hemostat, opening the lesion (arrow 2)
