Reporters obtained the following quote from the background information supplied by the inventors: "Field of the Invention
"The present invention discloses an artificial joint assembly, such as is particularly configured for employing as a retrofit knee joint, and which combines pairs of end anchored artificial components incorporated into each of first and second reconditioned joint defining surfaces for providing increased wear life in tandem with evenly distributed wear pattern/profile as well as enhanced flexibility and mobility.
"The prior art is well documented with examples of artificial knee implant assemblies. These include such as the spherical knee joint prosthesis of Bosredon, U.S. Pat. No. 6,117,175, the total knee implant of Byrd et al., US 2010/0191342 and the artificial implant component and method for securing disclosed in Elias, U.S. Pat. No. 5,480,443."
In addition to obtaining background information on this patent, NewsRx editors also obtained the inventors' summary information for this patent: "The present invention discloses a joint assembly incorporated into reconditioned end surfaces established between an upper bone and an opposing lower bone. The assembly includes a first component anchored into a first of the reconditioned bone end surfaces and exhibiting a first exposed support surface and a second component anchored into a second of the reconditioned bone end surfaces and exhibiting a second exposed support surface further including a flexible and conveyable closed loop belt relatively displaceable upon contact with the first support surface.
"At least one of the components may further exhibit an arcuate shaped support surface and can be constructed of at least one of a metal, plastic, polymer or composite material. In one desired arrangement, a first pair of components are arranged at a first side of said assembly affixed to reconditioned opposing surfaces associated with first and second knee joint defining bones, with a second identical pair arranged at an opposite second side. This can further include a 1/2 implant assembly associated with a selected side of the joint defining bones, and such as in combination with a natural remaining portion of the joint.
"The second component may further incorporate a subassembly including a pair of side assembleable outer portions capturing the belt therebetween such that an upper portion of said belt is exposed for contacting said first component. Each of the side assembleable outer portions further includes opposing and mating receiving channels for supported the belt in conveyable fashion therebetween. The side assembleable outer portions each may also include aligning tab and slot portions for inter-assembling about the belt."
