Abstract
Cartilage fibers and implants made therefrom are disclosed, with and without cartilage particles. Methods for making the cartilage fibers and the implants containing them are also disclosed. The implants may be pre-shaped, may be reshapable and, when implanted in a cartilage defect, the implants have good shape retention, little swelling, completely fill the cartilage defect and resist migration from the defect upon irrigation.
Claims19
A cartilage-derived implant for treating a cartilage defect, said implant comprising a plurality of cartilage fibers which are elongated pieces of cartilage tissue, each having three or more laterally oriented striations, wherein the striations of the cartilage fibers enable the cartilage fibers to entangle with one another to a greater degree than cartilage fibers without such striations and to form the implant which is capable of retaining its shape until reshaped and of conforming to and filling the cartilage defect when implanted in the cartilage defect.
