Systems and methods for ligament balancing during robotic surgery. One or more transducers are positioned within a knee joint to detect forces indicative of tension in ligaments and to provide output based on the detected forces. A distraction device is used to provide a distraction force to cause movement of a distal end portion of a femur relative to a proximal end portion of a tibia to increase tension in the ligaments. Information associated with output from the transducers is displayed for viewing.
