1. A computing device, comprising:
- a display having a first display screen;
an electronic controller; and
a memory device storing instructions executable by the electronic controller, the instructions being executable by the electronic controller to present a user interface on the first display screen, the user interface comprising;
a two-dimensional representation of an area of a provisional component, positionable between a femur and a tibia and including a plurality of sensors distributed over the area, the plurality of sensors including medical and lateral subsets of sensors, the medial subset of sensors comprising sensors from the plurality that are positioned between a center of the provisional component and a medial side of the provisional component, the lateral subset of sensors comprising sensors from the plurality that are positioned between a center of the provisional component and a lateral side of the provisional component, the representation comprising a medial-lateral direction and an anterior-posterior direction perpendicular to the medial-lateral direction;
a plurality of sensor icons having locations on the first display screen corresponding to the sensor locations on the provisional component; and
a medial force center indicator and a lateral force center indicator having respective positions on the first display screen determined by the electronic controller based on sensed force data and sensor locations from sensors in the medial subset of sensors and the lateral subset of sensors, respectively, the positions variable in the medial-lateral and anterior posterior directions based on force imbalance on the knee joint in the medial-lateral and anterior-posterior directions, respectively.

Abstract
Systems and methods for presenting force information related to a provisional is disclosed. A user interface may be provided for presenting objects on a display related to a knee joint, the user interface including a representation of an area of the knee joint for presentment on the display and a force center indicator for presentment on the display. The user interface providing an indication of when a position of the force center indicator corresponds to a desired position of the force center indicator.
