Disclosed herein is a patella clamp configured to grip a patient's patella. The patella clamp includes a clamping assembly, a ratchet arm assembly, and a handle assembly. The clamping assembly includes first and second patella grip portions mounted in opposing relationship. In use, actuation of the handle assembly moves the second patella grip portion towards the first patella grip portion to clamp the patient's patella. The handle assembly is configured to be moveably adjustable (e.g., rotatable) relative to the clamping assembly. For example, each of the first and second patella grip portions are coupled to mating features mounted on the ratchet arm assembly. Decoupling of the mating features allows the first and second patella grip portions to rotate about the longitudinal axis of the ratchet arm assembly. Thus arranged, the patella clamp is configured to enable the surgeon to reposition the handle assembly to provide increased visibility, etc.

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.

Cutting guides for use in orthopedic surgery are disclosed. In some embodiments, the cutting guides comprise monolithic polymer cutting blocks with one or more slots and guide inserts to allow for the provision of various desired surgical cuts to a bone by a cutting saw. The location and directionality of the cuts may be configured to match the geometry of a surgical implant.

Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.

A positioning guide system for guiding a surgical tool comprising a positioning guide and a user interface. The positioning guide comprising: an interface to correspond to a plurality of anatomic landmarks of a patient; a plurality of sensors to provide an output indicative of the proximity of the interface and one or more of the plurality of anatomic landmarks; and a tool guide, for a surgical tool, positioned relative to the interface. The user interface provides a user output indicative of correct positioning of the positioning guide and the anatomic landmarks of the patient based on the output of the plurality of sensors.

Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.

Disclosed herein are systems and methods of patella arthroplasty. A navigated patella clamp used in an arthroplasty procedure includes first and second movable jaw members and an actuation member coupled to the first and second jaw members for moving the first and second jaw members along a plane toward and away from one another. The patella clamp further includes a tracker and adjustable stylus for positioning the clamp on a patient's patella below a desired resection plane. The adjustable stylus coupled to the clamp is used to check the position and orientation of the clamp with respect to the patella to ensure the correct amount of bone will be resected from the patella corresponding to the thickness of a patella component that will be implanted on the resected patella.

A patella preparation system and method of using a patella preparation system. The patella preparation system includes a fixing device adapted to fixedly hold a patella, a guiding device linked to the fixing device to be moveable relative to the fixing device, preferably by translatory and/or tilting movements/motions, and an operation device for manually moving the guiding device relative to the fixing device individually and separately in a translatory and a tilting manner.
