What Is Shoulder Arthritis?

Shoulder arthritis refers to the gradual breakdown of cartilage in the shoulder joint, leading to pain, stiffness, and reduced mobility. Cartilage is a smooth, flexible tissue that covers the ends of bones within the joint, allowing them to glide smoothly against each other.

The condition commonly affects the glenohumeral joint (where the upper arm bone meets the shoulder blade) and the acromioclavicular (AC) joint (where the collarbone meets the shoulder blade).

Since the shoulder joint plays a crucial role in arm movement, arthritis can significantly impact daily function and quality of life.


Types of Shoulder Arthritis

Various forms of arthritis can affect the shoulder, each with distinct causes and symptoms. These include:

1. Osteoarthritis (Degenerative Joint Disease)

Osteoarthritis is the most common type of shoulder arthritis, occurring when the cartilage that cushions the joint wears down over time. This leads to pain, stiffness, and a grinding sensation. It is most prevalent in older adults and those with a history of shoulder injuries, repetitive overhead movements, or previous joint trauma.

2. Rheumatoid Arthritis (RA)

Rheumatoid arthritis is an autoimmune condition in which the immune system attacks the joint lining, causing inflammation, pain, and swelling. Unlike osteoarthritis, RA often affects both shoulders simultaneously.

3. Post-Traumatic Arthritis

This type develops after an injury, such as a fracture, dislocation, or severe sprain, which can cause cartilage damage, joint inflammation, and instability. Over time, these changes lead to progressive joint degeneration, pain, and reduced mobility, often resembling osteoarthritis but occurring earlier due to prior trauma.

4. Rotator Cuff Tear Arthropathy

A long-standing rotator cuff tear can lead to arthritis by disrupting shoulder joint stability, causing muscle imbalance and altered joint mechanics. This results in progressive cartilage wear, chronic inflammation, and worsening joint dysfunction, often leading to pain, weakness, and limited range of motion over time.

5. Acromioclavicular (AC) Joint Arthritis

AC joint arthritis affects the acromioclavicular (AC) joint and commonly develops due to age-related wear and tear or repetitive overhead movements, particularly in middle-aged adults, weightlifters, and overhead athletes. Often asymptomatic and found incidentally on imaging, symptomatic cases can cause pain, swelling, and restricted movement, especially during cross-body or overhead motions.

6. Avascular Necrosis (AVN)

Avascular necrosis occurs when the humerus loses blood supply, causing bone deterioration, joint degeneration, and arthritis. Though most common in the hip, it can affect the shoulder, knee, and other joints. Causes include trauma, prolonged corticosteroid use, alcohol misuse, and conditions like sickle cell disease, lupus, and clotting disorders. Initially asymptomatic, AVN can lead to pain, stiffness, and joint collapse if untreated.

Shoulder Arthritis Symptoms

Symptoms of shoulder arthritis may develop gradually and worsen over time, affecting daily activities and overall shoulder function. These include:

  • Pain – Worsens with movement and may persist even at rest due to inflammation and joint surface damage.
  • Stiffness – Reduced range of motion as cartilage loss and swelling restrict joint flexibility.
  • Weakness – Muscle weakness caused by pain, joint instability, and reduced use of the shoulder.
  • Swelling and Tenderness – More common in inflammatory arthritis conditions such as rheumatoid arthritis, where the immune system attacks the joint lining.
  • Grinding or Clicking Sounds – Caused by bone-on-bone contact as cartilage wears away, leading to friction within the joint.

Risk Factors for Shoulder Arthritis

Several factors contribute to the development of shoulder arthritis, including:

  • Age – The most common risk factor, as cartilage naturally wears down over time, making arthritis more prevalent in individuals over 50.
  • Repetitive Overuse – Frequent overhead activities, heavy lifting, or repetitive motions can accelerate cartilage wear and joint degeneration.
  • Previous Shoulder Injuries – Fractures, dislocations, or rotator cuff tears can damage cartilage and increase the risk of arthritis over time.
  • Inflammatory Conditions – Autoimmune diseases such as rheumatoid arthritis cause chronic joint inflammation, leading to cartilage breakdown.
  • Genetics – A family history of arthritis may increase susceptibility due to inherited joint structure or predisposition to cartilage degeneration.

Diagnosis of Shoulder Arthritis

Diagnosis of shoulder arthritis typically involves a combination of clinical examination and imaging tests to rule out other conditions with similar symptoms.

1. Medical History and Physical Examination

A doctor or specialist will review any history of previous injuries, repetitive strain, or underlying medical conditions that may contribute to arthritis.

This is followed by a physical examination, which includes assessing pain, stiffness, and weakness, as well as evaluating joint mobility and function to determine the extent of impairment.

2. Imaging Tests

Imaging helps confirm the diagnosis and assess the extent of joint damage:

  • X-rays – Identify cartilage loss, bone spurs, and joint space narrowing, which indicate arthritis progression.
  • MRI or CT Scans – Provide detailed images of soft tissues, including cartilage, tendons, and ligaments, helping to detect early-stage arthritis and associated damage.
  • Ultrasound – Can detect inflammation, fluid buildup, and early joint changes, particularly in inflammatory arthritis conditions.

Shoulder Arthritis Treatment

Treatment varies based on severity and the type of shoulder arthritis. Options range from conservative management to surgical intervention.

Treatment Description & Purpose
Non-Surgical Management
Pain Management Includes medications such as non-steroidal anti-inflammatory drugs (NSAIDs), which help reduce pain and inflammation by targeting joint swelling and discomfort. Additionally, a cold compress can reduce inflammation and numb pain, while heat therapy relaxes muscles and improves blood circulation, aiding in symptom relief and flexibility.
Activity Modification Avoiding repetitive overhead motions, heavy lifting, and high-impact activities reduces stress on the joint, preventing symptom worsening and slowing arthritis progression.
Physiotherapy Strengthening exercises improve mobility, joint support, and flexibility, helping to reduce stiffness, maintain function, and slow disease progression.
Assistive Devices Braces or slings provide temporary support, reducing strain and improving comfort by stabilising the joint. They are often used during symptom flare-ups, recovery, or for severe arthritis to aid daily activities.
Injection-Based Treatment Includes corticosteroid injections for temporary pain relief and inflammation reduction, hyaluronic acid injections to improve joint lubrication and reduce friction, and Platelet-Rich Plasma (PRP) therapy, which uses a patient’s own platelets to promote healing and reduce inflammation.
Surgical Intervention
Arthroscopy A minimally invasive surgical procedure that uses a small camera (arthroscope) and specialised instruments to remove loose cartilage, bone spurs, or inflamed tissue from the joint. It can help improve mobility and reduce pain, but it does not reverse arthritis or prevent disease progression.
Shoulder Replacement Surgery (Arthroplasty) Surgery to replace the damaged joint surfaces with prosthetic implants to restore function and reduce pain. Total shoulder replacement is used for severe arthritis, while reverse shoulder replacement is often performed when rotator cuff damage is also present.
Resection Arthroplasty (for AC Joint Arthritis) A procedure that removes a small portion of the distal clavicle to relieve pain and restore mobility. It is primarily performed for AC joint arthritis, which results from cartilage degeneration, causing persistent pain and difficulty with cross-body movements.

Preventing Shoulder Arthritis

While some risk factors cannot be controlled, certain measures can help maintain joint health and reduce the risk of arthritis progression:

  • Avoid Repetitive Stress Injuries – Modify activities to reduce shoulder strain and prevent overuse-related damage.
  • Strengthen Shoulder Muscles – Regular strength training, including rotator cuff exercises, resistance band work, and scapular stabilisation, can enhance joint stability and support, reducing the risk of strain and injury.
  • Engage in Low-Impact Exercise – Incorporate low-impact activities like swimming, yoga, and resistance band exercises to maintain joint flexibility, improve circulation, and strengthen supporting muscles without placing excessive strain on the shoulder.
  • Early Treatment of Injuries – Proper rehabilitation of shoulder injuries prevents long-term complications that may contribute to arthritis.

When to See a Shoulder Specialist?

You should consider seeking a proper evaluation if you experience:

  • Persistent pain that does not improve with rest or medication.
  • Worsening symptoms despite conservative treatments like physiotherapy or pain management.
  • Limited mobility affecting daily activities such as reaching or lifting.
  • Pain at rest or during sleep, indicating potential progression of arthritis.
  • Swelling or noticeable joint changes such as deformity or instability.

Every patient deserves a treatment plan tailored to their needs. We start with non-surgical approaches before considering more invasive interventions.

Frequently Asked Questions (FAQs)

There is currently no permanent cure for shoulder arthritis, but symptoms can be managed effectively through targeted treatment. Non-surgical options such as medication, physiotherapy, and joint injections help reduce pain and improve mobility, while surgical procedures like shoulder replacement may be considered for advanced cases. Early diagnosis and ongoing management can significantly slow disease progression and maintain joint function.

Frozen shoulder and arthritis are different conditions, though both cause shoulder pain and stiffness. Frozen shoulder involves tightening of the joint capsule, leading to restricted movement, whereas arthritis results from cartilage wear or inflammation within the joint. Frozen shoulder often resolves gradually with physiotherapy, while arthritis is a degenerative process that requires long-term management.

The most suitable treatment for shoulder arthritis depends on its severity and cause. Mild to moderate cases often respond to non-surgical options such as anti-inflammatory medication, physiotherapy, and corticosteroid or hyaluronic acid injections. Severe arthritis that limits function may require surgical intervention like shoulder replacement to restore movement and relieve pain. It is advisable to consult an orthopaedic specialist to determine the most appropriate treatment plan for your condition.

Gentle exercises for shoulder arthritis include pendulum swings, wall slides, shoulder rolls, and resistance band strengthening. These movements help maintain flexibility, reduce stiffness, and support joint stability when performed under professional guidance. Low-impact activities like swimming or yoga can also improve circulation and shoulder mobility. It is important to avoid exercises that cause sharp pain or strain. Always follow the advice of your physiotherapist or specialist on the most suitable exercises for your condition.

Yes, arthritis can develop in both the neck and shoulder, sometimes at the same time. Arthritis in the cervical spine (neck) can cause pain that spreads to the shoulder, while shoulder arthritis originates in the glenohumeral or acromioclavicular joint. Because symptoms may feel similar, identifying the true source of pain is essential for proper management. If you experience ongoing neck or shoulder pain, it is advisable to consult an orthopaedic specialist for diagnosis and treatment.

Arthritis does not usually occur in the shoulder blade itself but can affect nearby joints such as the acromioclavicular or glenohumeral joint, leading to pain felt around or behind the shoulder blade. Pain from the neck or surrounding muscles can also spread to this area and feel similar to shoulder blade arthritis. Persistent or worsening discomfort should be professionally evaluated to determine the cause and appropriate treatment.

There is no instant cure for arthritis, but early and consistent treatment can significantly reduce pain and slow progression. Non-surgical options such as anti-inflammatory medication, physiotherapy, and joint injections help manage symptoms effectively, while lifestyle measures like low-impact exercise and avoiding overuse support long-term improvement. For advanced cases, surgery may be considered to restore function. It is advisable to consult an orthopaedic specialist for an appropriate treatment plan.

With shoulder arthritis, it is important to avoid repetitive overhead activities, heavy lifting, and high-impact movements that strain the joint. Ignoring pain, poor posture, or prolonged inactivity can also worsen stiffness and cartilage wear. Activities that cause grinding or sharp discomfort should be stopped immediately. Maintaining gentle movement and muscle strength through guided physiotherapy helps protect the joint. Always follow the advice of your doctor or physiotherapist to prevent further damage.

Weightlifting with shoulder arthritis is possible in some cases, but it must be approached cautiously. Light resistance exercises that strengthen the rotator cuff and surrounding muscles can help stabilise the joint and reduce pain, while heavy lifting or overhead presses should generally be avoided. Using proper form and avoiding movements that cause discomfort are crucial. Always consult your physiotherapist or specialist before starting or modifying a strength training routine.

Pain from shoulder arthritis can be managed with non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen, which help reduce inflammation and discomfort. In some cases, corticosteroid injections may offer short-term relief, while heat or cold therapy can ease daily symptoms. For those unable to take NSAIDs, other pain-relieving options may be prescribed. It is advisable to consult your doctor or specialist for the most suitable medication for your condition.

Shoulder arthritis most commonly develops after the age of 50 due to age-related cartilage wear, although it can appear earlier in those with previous shoulder injuries or inflammatory conditions. Osteoarthritis typically progresses gradually with age, while post-traumatic or autoimmune forms such as rheumatoid arthritis may affect younger adults. Maintaining shoulder strength and flexibility through regular exercise can help delay symptom onset.

Shoulder arthritis is not usually classified as a disability in Singapore, but severe cases can become disabling if pain and stiffness greatly limit daily function or employment. Under the Enabling Masterplan, disability refers to substantial and long-term limitations that restrict equal participation in work, education, or community life. While shoulder arthritis can affect mobility, most individuals improve with appropriate treatment and rehabilitation.
