Arthritis

What is Arthritis?

Arthritis is not a single disease but a term describing over 100 different conditions that cause pain, stiffness, and swelling in joints. The most common types are osteoarthritis and rheumatoid arthritis, each with different causes and treatment approaches.

Types of Arthritis

Osteoarthritis (OA)

The most common form, affecting over 32 million adults in the United States:

• Cause: Progressive breakdown of cartilage (the protective tissue covering bone ends)
• Affects: Weight-bearing joints (knees, hips, spine) and hands
• Onset: Usually develops gradually, typically after age 40
• Symptoms: Pain that worsens with activity, morning stiffness lasting less than 30 minutes, decreased range of motion

Rheumatoid Arthritis (RA)

An autoimmune disease affecting approximately 1.5 million Americans:

• Cause: Immune system mistakenly attacks the synovium (lining of joints)
• Affects: Usually symmetrical (both hands, both knees)
• Onset: Can occur at any age, most common between 30-50
• Symptoms: Morning stiffness lasting more than 1 hour, joint swelling, fatigue, fever

Gout

A form of inflammatory arthritis caused by uric acid crystal deposition:

• Cause: High uric acid levels form sharp crystals in joints
• Affects: Typically the big toe first, can involve ankles, knees, wrists
• Onset: Sudden, intense attacks often at night
• Symptoms: Excruciating pain, redness, warmth, swelling

Symptoms

Diagnosis

Medical Evaluation

• Physical examination: Assessing range of motion, joint swelling, tenderness
• Medical history: Family history, symptom patterns, functional impact
• Laboratory tests: Blood tests for inflammation markers, antibodies, uric acid
• Imaging studies: X-rays, MRI, ultrasound to visualize joint damage
• Joint fluid analysis: Examining fluid from swollen joints for crystals or infection

Key Diagnostic Tests

• Rheumatoid factor (RF) and anti-CCP: Antibodies often present in RA
• Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP): Markers of inflammation
• Uric acid levels: For gout diagnosis
• X-rays: Showing joint space narrowing, bone spurs, fractures

Management

Non-Pharmacological Approaches

Physical Activity:

• Low-impact exercises: Swimming, cycling, water aerobics
• Range-of-motion exercises: Stretching, gentle yoga
• Strength training: Building muscle to support joints
• Walking: Simple but effective for many types of arthritis

Heat and Cold Therapy:

• Heat: Relaxes muscles, increases blood flow - use warm towels, hot packs, warm baths
• Cold: Reduces inflammation, numbs pain - use ice packs for 15-20 minutes

Weight Management:

• Weight loss: Reduces stress on weight-bearing joints
• Even modest weight loss (5-10%) can significantly reduce pain

Assistive Devices:

• Canes, walkers: Reduce joint stress during walking
• Joint supports: Braces, elastic supports
• Adaptive equipment: Jar openers, reachers, special utensils

Medications

For Pain Relief:

• Acetaminophen: First-line for mild-moderate pain
• NSAIDs: Ibuprofen, naproxen (reduce pain and inflammation)
• Topical treatments: Creams, gels, patches

For Inflammatory Arthritis:

• Corticosteroids: Oral or injectable steroids for acute flares
• Disease-Modifying Antirheumatic Drugs (DMARDs): Methotrexate, sulfasalazine
• Biologics: TNF inhibitors, IL-6 inhibitors for RA
• Urate-lowering therapy: Allopurinol, febuxostat for gout
