摘要： 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 relative 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.

摘要： The invention concerns a tibial prosthetic component comprising a plate (100) for forming a tibial plateau of a tibia (16), wherein a peripheral region of the plate (100) has a thickness of less than 3 mm. The invention also concerns a tibial prosthetic component having a keel of depth less than 9 mm. The invention also concerns a method of selecting a tibial prosthetic component comprising receiving measurements of at least one physical attribute of an individual into whom the tibial prosthetic component is to be implanted, selecting a thickness of a plate (100) and depth of keel of the tibial prosthetic component based on the measurements and providing a tibial prosthetic component comprising a plate (100) having the selected thickness and a keel having the selected depth. The invention may also comprise implanting a tibial prosthetic component selected in accordance with this method into an individual and a kit comprising a plurality of prosthetic components comprising plates having different thicknesses with keels of different depths.

摘要： A femoral extension prosthetic component for use in a unicondylar meniscal bearing unicompartmental knee replacement is described. The femoral component comprises a securing element and a bearing surface, the securing element adapted to abut and be connected to a distal end of a femur bone, and the Dearing surface adapted to abut a meniscal bearing. The femoral component includes an entrapment portion adapted to extend beyond the meniscal bearing. Tibial components and meniscal bearings are also described, as well as methods of using such components.

摘要： A system for a unicompartmental knee replacement is described. The system can include a femoral prosthesis component, a tibial prosthesis component and a meniscal bearing. The meniscal bearing can be insertable between the femoral prosthesis component and the tibial prosthesis component. The meniscal bearing can include a first bearing surface configured to bear against the femoral prosthesis component, a second bearing surface opposed to the first bearing surface and configured to bear against the tibial prosthesis component, and a sidewall separating the first bearing surface from the second bearing surface, wherein the sidewall has a retention groove formed in a portion thereof, and wherein the meniscal bearing and the tibial prosthesis component are configured such that the retaining flange enters the retention groove on movement of the meniscal bearing relative to the tibial prosthesis component towards the medial wall.
