A joint prosthesis supporting assembly 10 comprisies a sub-frame 12 to be located between a joint replacement component 20 and a resected surface of a femur or tibia, and at least one extra-cortical fixation element 14 for securing the sub-frame 12 to the bone. The extra-cortical fixation elements 14 may have a tab 14a which extends into a slot 12a in the sub-frame, and may be secured to the bone with fasteners extending through apertures (see figure 4). The sub-frame 12 provides a stable, secure platform for attachment of the joint replacement component 20. The extra-cortical fixation element 14 provides for loads to be transferred and helps to stabilise the sub-frame 12 and therefore any joint replacement component 20 attached to it. The arrangement is particularly suited for use in revision procedures, allowing the use of primary joint replacement components therein. |
