Resection arthroplasty is one of the most common procedures for surgically treating AC Joint Arthritis. It involves the removal of the last half-inch of the collarbone – leaving a space between the acromion, on the roof of the shoulder blade, and the cut end of the collarbone. The main ligaments remain intact.

Scar tissue then develops to replace the joint and allow movement to occur without further abrasion of the ends of the arthritic bone. The procedure maintains the flexible connection between the acromion on the shoulder blade and the collarbone.

Resection arthroplasty can be done as open surgery with a small one-inch long incision, or arthroscopically. Recovery is similar with both procedures.

Patients usually return home wearing an arm sling. Stitches are removed approximately one week later and movement becomes easier each day thereafter. A series of rehabilitative and strengthening exercises assist in the full resumption of movement over the next several months.
