20 Claims

1. An orthopaedic surgical instrument system for determining a joint force of a patient's knee joint, the orthopaedic surgical instrument system comprising:

a tibial paddle having an upper housing surface and a lower housing surface opposite the upper housing surface,

a sensor array positioned between the upper and lower housing surfaces of the tibial paddle and configured to generate a sensor signal indicative of the joint force while the tibial paddle is positioned between the patient's tibia and the patient's femur,

a central hub extending upwardly from the upper housing surface of the tibial paddle, and

a tibial trialing component that is selectively positionable around the central hub in (i) a first orientation that prevents rotation of the tibial trialing component relative to the tibial paddle and (ii) a second orientation that provides a limited range of rotation of the tibial trialing component relative to the tibial paddle.
