Publication number: 20130297020Abstract: A bearing component 2 for a joint replacement prosthesis comprises a first bearing element 4; a second bearing element 6, and a linking element 8, operatively connecting the first and second bearing elements 4, 6 and permitting relaDative motion there between. The flexible linking element 8 prevents dislocation of mobile bearings in a total knee replacement prosthesis. The invention also relates to a bridging element which retains the linking element 8 with some play, which acts as a ligament support 2051, and which causes a deflection of the line of action of a ligament 1018. A joint replacement prosthesis is also disclosed comprising a biasing element 1140 or a tensioning element 1220 operatively coupled to the artificial ligament 1018. The biasing element 1140 or tensioning element 1220 may be housed in the stem of a tibial tray 1006.Type: ApplicationFiled: June 21, 2013Publication date: November 7, 2013Inventors: David Wolfson, Russell Llloyd, John Joseph O'Connor, Mohammed Imran Khan, David Wycliffe Murray, Christopher Alexander Dodd, John William Goodfellow
