Orthopaedic surgical system for determining joint forces of a patients knee joint
First Claim
1. An orthopaedic surgical system for determining a joint force of a patient'"'"'s joint, the orthopaedic surgical system comprising:
- a sensor module comprising a tibial paddle shaped to be positioned between a proximal end of a patient'"'"'s tibia and a distal end of a patient'"'"'s femur, an elongated handle secured to the tibial paddle, and a sensor array positioned in the tibial paddle and configured to generate sensor signals indicative of a joint force between the patient'"'"'s tibia and femur, the tibial paddle including an inner sidewall defining a centrally-located aperture, anda surgical instrument attachable and detachable from the tibial paddle of the sensor module, the surgical instrument including a plurality of lower retainer clips receivable in the centrally-located aperture to attach the surgical instrument to the tibial paddle.

Abstract
An orthopedic surgical system includes a sensor module for determining the joint force of a patient'"'"'s knee joint and an adaptor for coupling various tibial trialing components to the sensor module. The sensor module includes a tibial paddle to which the adaptor is configured to couple. The adaptor and tibial paddle include structures that control the orientation at which the adaptor is attachable to the tibial paddle. Some tibial trialing components may be positioned over the adaptor in a mobile orientation that facilities rotation of the tibial trialing component relative to the tibial paddle or a fixed orientation that restricts the rotation of the tibial trialing component.

-
a sensor module comprising a tibial paddle shaped to be positioned between a proximal end of a patient'"'"'s tibia and a distal end of a patient'"'"'s femur, an elongated handle secured to the tibial paddle, and a sensor array position in the tibial paddle and configured to generate sensor signals indicative of a joint force between the patient'"'"'s tibia and femur, the tibial paddle including an inner sidewall defining a centrally-located aperture, an adaptor attachable and detachable from the tibial paddle of the sensor module, the adaptor including a hub, a plurality of lower retainer clips extending downwardly from the hub and receivable in the centrally-located aperture to attach the adaptor to the tibial paddle, and a plurality of upper retainer clips extending upwardly from the hub and sized such that the plurality of upper retainer clips are not receivable in the centrally-located aperture, and a tibial trialing component that is positionable over the adaptor in a first orientation that limits rotation of the tibial trialing component to rotate relative to the tibial paddle and a second orientation that allows rotation of the tibial trialing component relative to the tibial paddle. - View Dependent Claims (23, 24)
