Abstract
Provided herein are biomimetic osteochondral implants that are generally useful for the at least partial resurfacing of damaged cartilage within a joint. The implants are constructed to have a modular, layered structure in which the physical properties (e.g., stiffness and lubricity) or dimensions of each layer can be adjusted (e.g., by using the appropriate material and controlling the thickness thereof) based on the anatomy to be replaced. For example, the material and or thicknesses of the layers can be selected to approximate the physical properties and/or dimensions of cartilage (and, optionally, chondral and subchondral bone). Also provided herein are methods of treatment involving the use of said biomimetic osteochondral implants to repair an osteochondral defect in a joint.
