An orthopaedic surgical instrument system includes a compression socket configured for coupling with a selected one of a number of compressible bases. Each compressible base is shaped to conform with a posterior surface of either a dome patella implant component or an anatomical patella implant component.

A computer-assisted surgery system for performing a surgical procedure at a target area on a patient's anatomy. Said computer-assisted surgery system includes a robotic device having a plurality of joints and a plurality of actuators and a guide mechanically coupled to said robotic device. Said robotic device is configured to constrain said guide according to a pre-defined virtual geometry with said guide being movable along said pre-defined virtual geometry toward the target area on the patient's anatomy. The computer-assisted surgery system also includes a computer in communication with said robotic device and configured to command said robotic device to operate in one of a first mode in which said guide is manually manipulated by a user or a second mode in which said robotic device operates autonomously.

A patellar resection guide includes a frame, a first jaw, and a second jaw. The frame includes a first end, at which the first jaw is disposed, and a second end opposed to the first end at which the second jaw is disposed. The guide further includes an arm with a planar surface for guiding a cutting tool. The arm is either or both of rotatable and translatable relative to the frame.

A guide is disclosed that operates to guide in the creation of a bone spur to facilitate harvesting a quadriceps tendon and includes an end having a width equal to a desired graft width with a terminal slope equal to a cutting angle desired. In use, the guide may be initially positioned parallel to the femur to form guide cuts in the patella. The guide is then rotated ninety degrees to allow an angled cut at the guide cut. The guide is again rotated, this time one hundred eighty degrees and a second angled cut made on the other guide cut. A final lateral cut is made and the bone spur may be lifted from the patella.

A computer-assisted surgery system for performing a surgical procedure on a patient's anatomy includes a robotic device, a guide coupled to the robotic device, and a computer in communication with the robotic device. The computer is configured to command the robotic device to selectively operate in one of a first mode in which the guide is manually moved by a user or a second mode in which the robotic device autonomously moves the guide. In the first mode, the robotic device is controlled by the computer to constrain motion of the guide to a predefined plane while allowing the guide to be manually moved along the pre-defined plane.

A computer-implemented method of improving a patello-femoral response is described. A computing system characterizes an anterior geometry of a patella and determines a position of a posterior apex of the patella in relation to one or more features of the anterior geometry of the patella. The computing system further receives location information related to the patella as a knee joint is moved through a range of motion. The computing system provides one or more recommendations to improve a patello-femoral response.
