Abstract: An implant system for implantation at a joint. The implant system includes an implant device with a body portion having first and second ends, and a first elongate member, extending from the first or second end of the body portion. The implant system has a corresponding fixation device with at least one latching element. The first elongate member has at least one cooperating element capable of cooperating with the at least one latching element of the fixation device in use.

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.
