Shoulder Replacement
A procedure that replaces the damaged surfaces of the shoulder joint with smooth implants, relieving arthritis pain and restoring reliable, comfortable movement.

About this procedure
Shoulder replacement removes the worn ball and socket and replaces them with metal and plastic components. In an anatomic replacement, the new parts mirror the natural anatomy. In a reverse replacement, the ball and socket are switched, which lets other muscles power the arm when the rotator cuff is no longer intact.
Dr. Sonntag reserves replacement for patients whose arthritis or damage no longer responds to conservative care. He selects between anatomic and reverse designs based on the condition of the rotator cuff and the shape of the joint, tailoring the choice to each patient's anatomy and functional goals.
What to expect
- Significant, lasting relief from arthritis pain
- Choice of anatomic or reverse design to fit the shoulder
- Reverse option restores motion even with rotator cuff damage
- Improved ability to return to daily activities*
Most patients wear a sling for several weeks and progress through physical therapy over the following months, with functional recovery typically continuing for six months to a year.*
