Abstract
This disclosure is directed to a resilient interpositional arthroplasty implant for application into a joint to pad cartilage defects, cushion, and replace or restore the articular surface, which may preserve joint integrity, reduce pain and improve function. The implant may endure variable joint compressive and shear forces and cyclic loads. The implant may repair, reconstruct, and regenerate joint anatomy, and thereby improve upon joint replacement alternatives. The walls of this invention may capture, distribute and hold living cells until aggregation and hyaline cartilage regrowth occurs. The implant may be deployed into debrided joint spaces, molding and conforming to surrounding structures with sufficient stability so as to enable immediate limb use after outpatient surgery. Appendages of the implant may repair or reconstruct tendons or ligaments, and menisci by interpositional inflatable or compliant polymer arthroplasties that promote anatomic joint motion.
