The present disclosure relates to a device for repairing a patient patella. The device comprises a patellar trial piece and a patellar implant. The patellar trial piece has selectable variable weights to correct mechanical properties of the patient patella. Such mechanical properties to be corrected include a moment of inertia and/or a center of gravity of the patient patella. The patellar implant has embedded weights correspond to the variable weights of the patellar trial piece. In one embodiment, the patellar trial piece has a plurality of variable weights to be inserted into a plurality of holes in the patellar trial piece. The weights are made of different materials. In another embodiment, the patellar trial piece has a rounded top surface and a substantially flat bottom surface with a plurality of pegs. The pegs are selected from pegs with variable weights that are made of different materials.

A system and method for prosthesis fitting in joints comprising an artificial condyle and a spacer which cooperates with the condyle to form an artificial joint. The spacer embedded with at least one sensor which is responsive to a force generated between the condyle and the spacer. The artificial joint is adapted to move between a flexed position and an extended position defining a range of motion. The sensor is responsive to the force and generates an output representative of that force. The output is transmitted, either wirelessly or other, to a processor which utilizes an analysis program to display a representation of the forces applied. A practitioner utilizing the displayed analysis may intraoperatively determine the adjustments and balancing required within the artificial joint. The system may also utilize a ligament tension sensor which generates generates data representative of tension on a ligament of the artificial joint, and a joint angle sensor responsive to the range of motion of the artificial joint. The processor may be adapted to store the outputted sensor data to provide the practitioner with statistically relevant historical data.

An apparatus for reducing a fracture in a bone and attaching a plate to the bone includes a first sub-assembly configured to reduce the fracture, and a second sub-assembly integrated with said first sub-assembly in a single surgical instrument. The second sub-assembly is configured to hold the plate against the bone concurrently with reduction of the fracture by the first sub-assembly.
