Shoulder osteoarthritis

Shoulder osteoarthritis is a degenerative joint condition characterised by the progressive wear and breakdown of protective cartilage, resulting in joint pain, stiffness, and restricted movement.

What causes shoulder osteoarthritis?

Shoulder osteoarthritis is primarily a degenerative condition, but several factors can accelerate its onset: Age-related wear and tear (Primary OA): Natural wear and erosion of cartilage over many years of routine joint use. It predominantly affects middle-aged and older adults. Post-traumatic osteoarthritis: Develops following a significant prior injury, such as a shoulder dislocation, labral tear, or bone fracture that permanently altered joint mechanics. Rotator cuff tear arthropathy: Long-standing, untreated large rotator cuff tears can cause the ball to shift out of alignment within the socket, leading to abnormal friction and severe wear on the upper socket rim. Avscular necrosis (AVN): Disruption of blood supply to the head of the humerus causes cartilage collapse and rapid joint degeneration.

Common symptoms

  • Deep, aching pain within the shoulder joint that worsens with movement or joint loading
  • Pain at night, making it difficult to find a comfortable sleeping position
  • Progressive joint stiffness and loss of range of motion, particularly when reaching overhead or rotating the arm
  • A grinding, cracking, or crunching sensation (crepitus) when moving the shoulder
  • Pain when lifting moderate objects or carrying out daily personal care tasks

 

How is shoulder osteoarthritis diagnosed?

Diagnosing shoulder osteoarthritis involves a comprehensive clinical examination by your consultant to evaluate joint stiffness, pain triggers, muscle strength, and functional limitations.

How is it treated?

Treatment plans are tailored based on your age, activity levels, symptom severity, and the stage of cartilage degeneration revealed in your diagnostic imaging.

Treatment routes for shoulder osteoarthritis

In the early to moderate stages, treatment focuses on relieving pain and maintaining joint mobility without surgery:

  • Activity modification: Adapting daily routines and avoiding heavy overhead loading to minimize joint strain.
  • Medication: Over-the-counter or prescribed non-steroidal anti-inflammatory drugs (NSAIDs) to reduce joint inflammation and pain.
  • Physical therapy: Targeted exercises to maintain shoulder girdle mobility and strengthen surrounding rotator cuff and back muscles to support the joint.
  • Intra-articular injections: Steroid injections can rapidly reduce joint inflammation and pain for several months. Joint lubricant injections (hyaluronic acid) may also be offered to improve joint fluid viscosity and reduce friction.

 

Recovery from shoulder osteoarthritis

0–2 weeks

Initial protection and healing

Following surgical debridement or joint replacement, your arm will be supported in a sling to manage swelling and protect soft tissue repairs. Focus on pain control, applying ice, and performing gentle hand, wrist, and finger exercises. Surgical dressings must stay clean and dry until stitches are checked at 10 to 14 days.

2–6 weeks

Passive to active-assisted movement

Under physical therapy guidance, sling use is gradually phased out. Exercises progress from passive joint movements to active-assisted mobility to prevent stiffness without overloading the joint.

6–12 weeks

Active mobility and functional rehabilitation

Active unassisted arm movements are reintroduced as comfort allows. Rehabilitation focuses on strengthening the shoulder girdle, restoring functional overhead reach, and resuming light daily activities.

3–6 months

Advanced recovery and long-term joint function

Rehabilitation shifts toward building endurance, functional strength, and low-impact sport conditioning. Full recovery following shoulder replacement surgery typically takes 6 to 12 months.

How to pay

We offer flexible options depending on how you choose to access care at Fortius. Whichever option you choose, we’ll help make the process clear and straightforward from the start.

Private medical insurance

Private medical insurance

If your care is covered by private medical insurance, we’ll usually invoice your insurer directly. Please check your policy in advance and request an authorisation code if your insurer requires one. You’ll be responsible for paying any policy excess or costs that aren’t covered by your insurance.

Paying for yourself

Paying for yourself

You don’t need private medical insurance to access care at Fortius. If you’re paying for your own treatment, our team will explain the costs clearly and provide a personalised quote before you decide whether to go ahead.
