ABSTRACT:
A resorbable extracellular matrix for reconstruction of cartilage tissue includes a purified collagen II derived from natural cartilage tissue from which non-collagen proteins have been removed. The matrix can be utilized as a scaffold implant for meniscal or vertebral cartilage regeneration.
