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.

Methods and apparatus for mid-flexion balancing during knee arthroplasty

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.
