摘要： A kit of parts for use in unicondylar knee replacement of a patient having a femur and a tibia comprises a drill guide and an intramedullary rod, the intramedullary rod being sized to fit within the intramedullary canal of the femur of the patient. The drill guide is arranged so as to engage a distal end of the intramedullary rod to that which engages the patient's intramedullary canal, and is formed with a foot portion sized to fit between the patient's femur and tibia before any bone is removed from the femur or tibia. The drill guide provides a guide for drilling of at least one hole in the femur. A further kit of parts for use in unicondylar knee replacement of a patient having a femur and a tibia comprises a femoral component for implantation in the femur, the femoral component having a bearing surface having a radius of curvature, and a guide spoon. The guide spoon has a bowl-shaped portion with an internal radius of curvature the same as that of the bearing surface, and a handle portion extending from the bowl-shaped portion. Methods of performing unicondylar knee replacement are also described.

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.
