Signs and Symptoms

Common Symptoms

1. Pain: Patients typically report a deep, aching pain in the shoulder, which may worsen with activity and improve with rest. Pain can also radiate down the arm[6].
2. Stiffness: Morning stiffness or stiffness after periods of inactivity is common, often lasting less than 30 minutes[6].
3. Reduced Range of Motion: Patients may experience difficulty in performing overhead activities or reaching behind their back due to limited mobility in the shoulder joint[6].
4. Crepitus: A grating sensation or sound may be felt or heard during shoulder movement, indicating joint surface irregularities[6].

Physical Examination Findings

• Tenderness: Palpation of the shoulder may reveal tenderness over the joint line and surrounding soft tissues[6].
• Swelling: Mild swelling may be present, although significant effusion is less common in primary osteoarthritis compared to inflammatory conditions[6].
• Deformity: In advanced cases, joint deformities may develop, including changes in shoulder contour due to bone spurs or joint space narrowing[6].

Diagnostic Considerations

Imaging Studies

• X-rays: Radiographic findings typically include joint space narrowing, subchondral sclerosis, osteophyte formation, and possible cysts in the bone adjacent to the joint[6].
• MRI: While not routinely used for diagnosis, MRI can help assess the extent of cartilage loss and other soft tissue changes if needed[6].

Differential Diagnosis

It is essential to differentiate primary osteoarthritis from other shoulder conditions, such as:
- Rotator cuff tears
- Rheumatoid arthritis
- Shoulder impingement syndrome
- Avascular necrosis
