Abstract
A tibial element for a replacement knee prosthesis has a tibial tray, fastening connector for securing an attachment element to the lower part of the tray, and also provided with independently operable securing boss at its upper end which engage a cooperating construction on a bearing component to secure the bearing component to the upper part thereof. The fastening connector allows for a stronger construction than the previous arrangements and it also allows for a convenient modular construction which will allow a standard modular tray to be employed with various types of bearing construction, for example, a fixed component or a sliding component.
