Abstract
An orthopaedic surgical instrument system includes a sensor adapter and multiple surgical instruments. The sensor adapter includes a housing with a force sensor positioned within the housing and a sensor contact configured to transfer force to the force sensor extending from the housing. Each surgical instrument includes a sensor connector configured to receive the sensor adapter at a predetermined location relative to the surgical instrument. Each sensor adapter further includes a registering feature to engage an anatomical feature of a patient or another surgical instrument. The surgical instruments may include a shim that may be attached to a gap assessment tool or a tibial insert trial. Methods associated with the surgical instrument system are also disclosed.
