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.

Abstract: Joint balancing methods and apparatus for arthroplasty procedures are disclosed. An example knee balancing jig may include a tibial placement guide configured for mounting to a tibial reference in a generally medial-lateral orientation in position generally anterior to a knee and/or at least one balancing assembly. The balancing assembly may include a vertical guide configured to releasably mount to the tibial placement guide in a generally inferior-superior orientation, at least one posteriorly extending paddle selectively vertically movable along the vertical guide, the paddle configured to selectively engage a distal femur and/or a proximal tibia, and/or at least one pin guide selectively vertically movable along the vertical guide, the at least one pin guide comprising at least one opening configured to receive at least one of a drill bit and a bone pin therethrough.

Abstract: Joint balancing methods and apparatus for arthroplasty procedures are disclosed. An example apparatus includes a knee arthroplasty set of guides comprising: (a) a femoral guide configured to mount to a distal femur, and (b) a tibial guide configured to mount to a proximal tibia, where the femoral guide and the tibial guide are configured to engage one another and lock in an angle between a longitudinal axis of the distal femur and a longitudinal axis of the proximal tibia of 30-70 degrees.

Abstract: Joint balancing methods and apparatus for arthroplasty procedures are disclosed. An example method of preparing a knee to receive a knee implant includes: (a) positioning a knee comprising a distal femur and a proximal tibia at a mid-flexion angle; (b) performing soft tissue balancing of the knee at the mid-flexion angle; (c) determining a location of a posterior chamfer cut of the distal femur configured to engage the posterior chamfer angle of a femoral component of a knee implant based at least in part upon the soft tissue balancing of the knee at the mid-flexion angle; and, (d) resecting the distal femur to create the posterior chamfer cut.
