Polyosteoarthritis: Understanding Generalized Joint Pain and Causes

Polyosteoarthritis (generalized osteoarthritis) involves degenerative changes in ≥3 joint groups. It is the most common form of arthritis, driven by "wear and tear" plus metabolic/inflammatory factors.

Risk Factors

• Age (>50), female sex, obesity (mechanical + adipokine effects)
• Genetics (heritability ~40–65%)
• Joint injury/surgery, repetitive occupational loading
• Metabolic syndrome, diabetes (systemic inflammation)
• Congenital dysplasia, ligamentous laxity

Commonly Affected Joints

• Distal/proximal interphalangeal (Heberden's/Bouchard's nodes)
• First carpometacarpal (thumb base)
• Knees, hips, spine (facet joints), first MTP (bunions)

Symptoms

• Activity-related pain, improving with rest (early); constant pain (late)
• Morning stiffness <30 min
• Crepitus, bony enlargement, reduced ROM
• Functional limitation (grip, walking, stairs)

Diagnosis

Clinical + X-ray (joint space narrowing, osteophytes, subchondral sclerosis, cysts). Labs usually normal (rule out inflammatory arthritis).

Management (Multimodal)

• Core: Exercise (aerobic + strengthening), weight loss if overweight, education.
• Pharmacologic: Topical NSAIDs first; oral NSAIDs (lowest dose, shortest time, PPI if risk); duloxetine; intra-articular corticosteroids (flare); avoid opioids.
• Adjuncts: Braces, orthotics, cane, thermal therapy.
• Surgery: Joint replacement (knee/hip) for end-stage refractory disease.

Key Point

No disease-modifying drugs (DMOADs) yet approved. Management focuses on symptom control, function preservation, and quality of life. Early, consistent non-pharmacologic therapy is most impactful.
