Shoulder Arthritis

Diagnosis involves a physical exam and imaging. X-rays reveal joint space narrowing, bone spurs, or bone-on-bone contact. MRI may be used to evaluate the condition of the rotator cuff tendons, especially in suspected cuff arthropathy.

Non-surgical options include activity modification, physical therapy, anti-inflammatory medications, and corticosteroid injections. If symptoms persist and quality of life is affected, shoulder replacement surgery may be recommended.

In an anatomic total shoulder replacement, the damaged humeral head is replaced with a metal ball, and the socket is replaced with a plastic implant. This option is typically used when the rotator cuff is intact and functioning.

In a reverse shoulder replacement, the normal ball-and-socket arrangement is flipped: a ball is placed on the socket side, and a socket on the humeral side. This design allows the deltoid muscle to compensate for a deficient rotator cuff, making it ideal for rotator cuff arthropathy.

Recovery takes 4 to 6 months. A sling is worn for a few weeks, followed by physical therapy to regain motion and strength. Most patients return to daily activities within 3 months, with continued improvement over time.

Recovery is similar to anatomic replacement though patients may return to daily activities sooner. Most patients experience significant pain relief and improved function within 3 to 6 months, even with limited or absent rotator cuff function.
