Abstract: A modular patella trial system and method is provided. A modular patella trial includes an articular element and at least one sizing element. The articular element has a length, a width, and a thickness. The articular element has a posterior and anterior surfaces separated by their thickness. The anterior surface has protrusions extending outwardly. Any of the sizing elements have a length, width, and thickness. Any such sizing elements have posterior and anterior surfaces separated by their thickness. At least one aperture extends through the posterior and anterior surfaces of the sizing elements. Such apertures are capable of receiving a corresponding protrusion of the articular element. The modular patella trial has a thickness substantially equal to the total of the thicknesses of the articular element and the sizing elements used in conjunction with the articular element.

Abstract: Disclosed herein are apparatuses and methods for performing joint balancing procedures. The apparatus may have femoral paddle and a tibial paddle attached to a housing. The housing may include a distraction mechanism to vary the space between the femoral paddle and the tibial paddle. The tibial paddle may lie entirely within the femoral paddle in a closed position. A load sensor may be placed in the femoral paddle to measure ligament tension. The apparatus may be inserted into a knee joint and positioned to remain within the knee joint during flexion and extension of the knee without everting a patella.

Abstract: A method for aligning an orthopedic implant in a joint replacement includes determining the bone and cartilage deficiency from an undegenerated state caused by wear of a joint. Then a resection of a bone in the joint is made based on the deficiency of bone and cartilage from the undegenerated state and the size of a joint implant so as to locate the joint surface of the implant in the undegenerated cartilage location. The condylar wear from the undegenerated states may be assessed at a distal and posterior location on each of a medial and a lateral femoral condyle. A distal cut is made on the femur at a location adjusting for the condylar wear from the undegenerated state. The distal cut varus-valgus angle is oriented parallel to a plane across the distal femur after adjusting for wear in the distal location on the medial and lateral condyle.

Abstract: A patella clamping device has a handle having a first arm and a second arm, the arms each having a first gripping end and a second clamping end. The clamping ends are movable towards the opposite arm by action on the gripping end of each arm. The clamping ends of the first and second arms comprise opposed clamping surfaces. The clamping end of each arm has a body portion having spaced first and second surface defining the opposed surface of each arm. A plurality of pins extend from the first to the second surface. A rotatable toothed jaw member is pivotally mounted on each of the pins. The jaw member has at least one tooth extending outwardly of the opposed surface of each arm for engaging the patella. Each body has a third surface spaced from the second surface to create a slot for receiving a saw blade.

Abstract: A method and instrument is used for inserting a bone screw through a hole in a bone plate into bone at a maximum angulation of a bone screw central longitudinal axis with respect to a central axis of the hole. The maximum angulation places the head of the bone screw at or below an outwardly facing surface of the bone plate. The instrument has a distal end including a gauge element spaced proximally from an end surface of the distal end when in contact with a counterbore surrounding the plate hole a distance less than a depth of the counterbore. The instrument is tilted with respect to a central axis of the bone plate hole to an angle wherein the gauge element remains at or below the outwardly facing surface of the bone plate adjacent the counterbore. A hole is drilled through a guide bore in the instrument.
