Abstract: An implant device used to replace and restore the function of the knee meniscus in a human. The compliant, yet resilient device is comprised of a biocompatible, non-degradable three-dimensional body comprised of at least a central body, a second structure, a third structure, and a coating. The device is concentrically aligned wherein the second structure is adjoined to the central body wherein the third structure is adjoined on the central body opposite of the second structure. The third structure further features a first and a second pulling element which is coupled to the central body and forms the outer periphery and major circumference of the device. The device is comprised of multiple components which provide tensile strength, compressive resilience, and attachment mechanisms for replacing the meniscus. Each structure is comprised of multiple surfaces which are further reinforced, separated, and connected by an individual plurality of vertical elements.

Abstract: A composite joint implant device replaces or repairs damaged meniscus tissue in an animal or human. In one embodiment, a composite joint implant comprises a polymeric body which is reinforced with a pre-formed engineered ligature mechanism. The ligature reinforces the polymeric body around the circumference and is used for attaching the device within an animal or human body. The ligature mechanism internally supports the transmission of vertical loads into tensile stresses. The ligature mechanism can be coated with a compatible material to promote integration with the polymeric body and coated with an encapsulation material.
