A kit for use in knee replacement surgery includes a trial patella component and a patella implant component. The trial patella component includes a backing plate having a backing surface for positioning against a patient's patella, and at least one sensor which can generate a signal corresponding to the compressive load applied to the trial patella component, and a first bearing plate which can be fitted to the backing plate and which, when fitted to the backing plate, provides a bearing surface for articulation against a bearing surface on the patient's femur. The patella implant component has a backing surface for fixation to a patient's patella instead of the backing surface of the trial patella component, and a bearing surface for articulation against a femoral bearing surface. The thickness of the patella implant component is greater than the thickness of the trial patella component when the first bearing plate is fitted to the backing plate, the difference between the said thicknesses being at least about 1 mm.

A femoral instrument for use in the intramedullary canal is described and includes an intramedullary rod having a tip at a free end. A body is attached to the intramedullary rod and has a face with a bone abutting portion. A centralizer mechanism is located within the rod and is operable to deploy and retract a plurality of members to engage and disengage an inner surface of the intramedullary canal. The length of the intramedullary rod from the tip to the face of the body is less than 30 cm. The instrument can also include an angular adjustment mechanism. The angular adjustment mechanism can have a plurality of formations and can be rotated about the longitudinal axis of the intramedullary rod to present at least a one of the formations to abut a portion of the body to define the relative angle between the body and the intramedullary rod.
