Abstract

Methods and devices are disclosed for soft tissue balancing of a knee joint during an arthroplasty procedure that include balancing the knee joint at or near mid-flexion, while maintaining the rotational position of the femur with respect to the tibia that replicates proper kinematic placement of these bones. Also disclosed are methods and devices for soft tissue balancing of a knee joint during an arthroplasty procedure that include balancing the knee joint at or near mid-flexion using one or more expansion devices that are not actively requiring monitoring and/or recording of forces applied by the bodily tissues, but instead uses incremental changes in actual length/height of the expansion device to determine whether the joint is properly tensioned or too lax.
