Shoulder instability and arthritis: When is surgery the right option?

Shoulder instability and arthritis are common conditions that can affect people of all ages, causing pain, weakness, and reduced mobility. Although many patients improve with non-surgical treatment, surgery may become necessary when symptoms begin to interfere with daily activities, work, sleep, or sport.

How do shoulder instability and shoulder arthritis occur?

Shoulder instability occurs when the shoulder joint becomes loose or repeatedly dislocates. This is often the result of sports injuries, trauma, or stretched ligaments. Patients may experience a sensation of the shoulder “giving way,” pain during movement, weakness, or recurrent dislocations. Younger and active individuals are particularly prone to instability following injury.

Shoulder arthritis develops when the cartilage lining the joint gradually wears away. As the protective cartilage deteriorates, bones begin to rub against each other, causing pain, stiffness, swelling, and restricted movement. Osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis are among the most common causes.

In many cases, conservative treatment is the first-line approach. Physiotherapy, analgesia, anti-inflammatory medication, lifestyle modification and corticosteroid injections for arthritis can effectively help to manage symptoms and improve function without the need for surgery.

When is surgery recommended for shoulder instability and shoulder arthritis?

Surgery is usually considered when non-surgical treatments no longer provide sufficient relief. For patients with recurrent shoulder instability, arthroscopic stabilisation surgery can repair damaged ligaments and improve joint stability. This minimally invasive procedure is commonly performed in individuals who continue to experience dislocations or instability despite rehabilitation.

For patients with advanced shoulder arthritis, joint replacement surgery may offer long-term pain relief and improved movement. Modern shoulder replacement techniques can restore function and significantly improve quality of life, especially when arthritis affects sleep, independence, or routine activities.

The decision to proceed with surgery depends on several factors, including symptom severity, activity level, age, imaging results, and overall health. A specialist shoulder surgeon can assess each patient individually and recommend the most suitable treatment approach. With early diagnosis and appropriate care, many patients can return to normal activities with reduced pain and improved shoulder function.
