Claim Text:
1. A prosthetic meniscus device for placement in a knee joint, comprising: a central portion having an upper surface for engagement with a femur and an opposing lower surface for engagement with a tibia, the central portion formed of a resilient polymer and being reinforced by an annular tension structure embedded therein; and an outer portion surrounding the central portion and having an increased thickness relative to the central portion, the outer portion including a plurality of flexible attachment members extending from adjacent the annular tension structure outwardly beyond an outer sidewall of the outer portion, wherein the plurality of flexible attachment members comprises a plurality of outwardly extending closed tethering loops enclosing at least a portion of the annular tension structure, and wherein the plurality of outwardly extending closed tethering loops are partially molded within the outer portion, wherein the annular tension structure comprises a plurality of fibers disposed circumferentially around the central portion, wherein the tethering loops are oriented perpendicularly to the annular tension structure and oriented to extend from superior to inferior such that an opening of each tethering loop is oriented along the outer sidewall of the prosthetic meniscus device such that the openings are in substantial alignment along the outer sidewall of the prosthetic meniscus device, wherein the plurality of tethering loops are adapted to inhibit extreme movement of the prosthetic meniscus device within the knee joint while permitting free floating of the prosthetic meniscus device over a significant range.
