1. A system for assessing measured forces that are applied by a medical professional during a gap assessment examination associated with an arthroplasty procedure for a patient, the system comprising:
a plurality of force sensors, each one of the plurality of force sensors respectively placed at i) a lateral ankle position and a medial ankle position, ii) a lateral foot position and a medial foot position, or iii) a lateral ankle position and a medial ankle position and a lateral foot position and a medial foot position, and each of the plurality of force sensors configured to detect an applied force at i) the lateral ankle position and the medial ankle position, ii) the lateral foot position and the medial foot position, or iii) the lateral ankle position and the medial ankle position and the lateral foot position and the medial foot position, respectively, during an abduction-adduction examination;
a computing device having at least one processor, a memory, and an output, and that is configured by executing instructions to:
receive, from each of the plurality of sensors during the abduction-adduction examination, data representing an applied force occurring during the abduction-adduction examination at each respective ones of i) the lateral ankle position and the medial ankle position, ii) the lateral foot position and the medial foot position, or iii) the lateral ankle position and the medial ankle position and the lateral foot position and the medial foot position;
calculate, using the received data, respective peak applied forces during the abduction-adduction examination in extension and flexion;
provide, via the output, information representing a correlation of the respective peak applied forces with information associated with at least one of:
at least one previous gap assessment examination for the patient by the medical professional;
at least one previous gap assessment examination for a different patient by the medical professional; and
at least one previous gap assessment examination for at least one different patient by at least one different medical professional.
