Abstract
A method and apparatus for measuring the forces acting on a patella includes a patella sensor comprising a sensor, a sensor cover, and a plurality of strain gages. The sensor cover is attached to the sensor and has an outer surface that is in contact with a femoral insert. The sensor cover transmits the forces acting on its outer surface to the sensor. The sensor has a plurality of strain gages mounted thereon to measure the forces acting on the sensor cover. The sensor is mounted to a resected patella. The measured forces are then used to obtain loading and boundary limits for the design of patellofemoral prosthetic components.
