Comprehensive care for shoulder arthritis and rotator cuff tear arthropathy, helping patients relieve pain, restore function, and return to the activities they love. Treatment options range from non-operative therapies to advanced shoulder replacement procedures tailored to each patient's goals and lifestyle.

Shoulder Arthritis & Replacement

Understanding the Shoulder

Anatomy of the Shoulder

The shoulder is one of the most mobile joints in the body, allowing us to reach, lift, throw, push, and perform activities overhead. It functions as a ball-and-socket joint, where the ball at the top of the upper arm bone (humeral head) fits into the socket of the shoulder blade (glenoid).

The surfaces of the ball and socket are covered with smooth articular cartilage, which allows the shoulder to move easily and painlessly. Surrounding the socket is a ring of cartilage called the labrum, which helps improve stability and keeps the shoulder centered during movement.

A group of four muscles and tendons known as the rotator cuff surrounds the shoulder joint. The rotator cuff helps lift and rotate the arm while also providing important stability. Together, the cartilage, labrum, rotator cuff, and surrounding muscles work to provide the shoulder with its unique combination of mobility and strength.

When these structures become damaged through arthritis, rotator cuff tears, injury, or normal wear and tear over time, patients may experience pain, stiffness, weakness, and loss of function.

What is Shoulder Arthritis?

Shoulder arthritis occurs when the smooth cartilage covering the ball and socket joint wears away over time, leading to pain, stiffness, and loss of function.

Common Symptoms

  • Shoulder pain

  • Night pain

  • Stiffness

  • Difficulty reaching overhead

  • Loss of motion

  • Difficulty with daily activities

What is Rotator Cuff Tear Arthropathy?

Rotator cuff tear arthropathy is a specific type of shoulder arthritis that develops after a large or irreparable rotator cuff tear. Without a functioning rotator cuff, the shoulder loses its normal mechanics, causing the humeral head to migrate upward and resulting in pain, weakness, and loss of function.

Common Symptoms

  • Difficulty lifting the arm

  • Shoulder weakness

  • Pain

  • Loss of function

  • Inability to reach overhead

Treatment Options

Non-Surgical Treatment

Most patients should attempt non-operative treatment before considering shoulder replacement surgery.

Treatment options include:

  • Activity modification

  • Physical therapy

  • Home exercise programs

  • Anti-inflammatory medications

  • Corticosteroid injections

Many patients can successfully manage symptoms without surgery.

When Is Surgery Recommended?

Shoulder replacement may be recommended when:

  • Pain becomes persistent

  • Sleep is affected

  • Motion is severely limited

  • Weakness impacts daily activities

  • Non-operative treatments are no longer effective

Frequently Asked Questions

Types of Shoulder Replacements

Shoulder replacement surgery is designed to relieve pain, restore function, and improve quality of life in patients with shoulder arthritis, rotator cuff tear arthropathy, fractures, and other complex shoulder conditions. The type of shoulder replacement recommended depends on the condition of the joint, the rotator cuff, and each patient's individual goals.

Reverse Shoulder Arthroplasty

This procedure changes the mechanics of the shoulder by placing a ball (glenosphere) on the socket side and a socket on the humeral side. This allows the deltoid muscle to compensate for a deficient rotator cuff.

Common Indications

  • Rotator cuff tear arthropathy

  • Massive irreparable rotator cuff tears

  • Pseudoparalysis

  • Complex proximal humerus fractures

  • Revision shoulder replacement surgery

  • Failed previous shoulder surgery

Goal

Restore shoulder function, improve strength, and relieve pain when the rotator cuff can no longer adequately stabilize or move the shoulder.

Anatomic Shoulder Arthroplasty

This procedure replaces both the ball and socket portions of the shoulder joint, recreating normal shoulder anatomy.

Common Indications

  • Primary glenohumeral osteoarthritis

  • Inflammatory arthritis

  • Post-traumatic arthritis

  • Intact and functioning rotator cuff

Goal

Relieve pain, restore motion, and improve shoulder function while maintaining normal shoulder biomechanics.

Hemiarthroplasty

This procedure involves replacing only the ball portion of the shoulder joint (humeral head) while preserving the native socket (glenoid).

Common Indications

  • Certain proximal humerus fractures

  • Avascular necrosis

  • Select younger patients with isolated humeral head disease

  • Cases where the glenoid cartilage remains relatively preserved

Goal

Relieve pain and restore function while preserving native shoulder anatomy when appropriate.

Shoulder replacement surgery may be recommended for patients with arthritis, rotator cuff tear arthropathy, or other conditions causing persistent pain and loss of function despite non-operative treatment. Depending on the diagnosis, several replacement options are available to restore comfort, mobility, and quality of life. Most shoulder replacement procedures are performed on an outpatient basis, allowing patients to return home the same day, while some patients may benefit from a short hospital stay based on their individual needs.

Shoulder Replacement Surgery

Goals of Surgery Include

The primary goals of shoulder replacement surgery are to:

  • Relieve pain

  • Restore shoulder motion

  • Improve strength and function

  • Enhance quality of life

  • Restore independence with daily activities

  • Help patients return to an active lifestyle

Recovery Timeline

Weeks 0–6

  • Sling for protection and comfort

  • Gentle motion exercises begin early

  • Focus on pain relief and restoring mobility

Weeks 6–12

  • Sling has been discontinued

  • Begin strengthening

  • Continued improvement in motion and daily function

Months 3–6

  • Return to many recreational activities

  • Significant improvement in comfort, strength, and function

  • Many patients resume activities such as golf, swimming, and pickleball

6+ Months

  • Continued gains in strength and endurance

  • Return to higher-demand activities as appropriate

  • Recovery continues to improve throughout the first year

A Personalized Recovery Plan

Every patient's recovery is unique. Rehabilitation is tailored to the type of shoulder replacement, underlying diagnosis, activity level, and individual goals. While recovery continues for several months, most patients experience meaningful improvements in pain, sleep, and day-to-day function much earlier in the process, allowing them to return to the activities they enjoy with greater comfort and confidence.
