An optical shape sensing system includes an optical shape sensing fiber (102) configured to be integrated with soft tissue in a region. An optical shape sensing module (115) is configured to receive feedback from the optical shape sensing fiber and determine position and orientations of the optical shape sensing fiber. A balancing module (140) is configured to employ the position and orientation of the optical shape sensing fiber to indicate when a balance criterion is met in soft tissue as a result of adjustments in the region.
