Arthritis is a general term for over 100 joint-related conditions that cause pain, swelling, stiffness, and reduced mobility. It can affect one or multiple joints, and symptoms may range from mild to debilitating. The most common types include Osteoarthritis (OA) and Rheumatoid Arthritis (RA), but others like Gout, Psoriatic Arthritis, and Lupus-related arthritis also exist.
Arthritis is not a single disease, but rather a category of joint disorders. It can result from wear and tear, autoimmune dysfunction, infections, or metabolic imbalances.
Other Name(s)
Joint inflammation
Degenerative joint disease (for OA)
Autoimmune arthritis (for RA, Psoriatic Arthritis)
Inflammatory arthritis
Rheumatic diseases
Difference Between Arthritis and Similar Conditions
| Condition |
Key Difference from Arthritis |
| Osteoarthritis |
Wear-and-tear; non-inflammatory |
| Rheumatoid Arthritis |
Autoimmune; symmetrical joint involvement |
| Gout |
Caused by uric acid crystals; sudden flare-ups |
| Lupus |
Systemic autoimmune disease; arthritis is one symptom |
| Fibromyalgia |
Widespread pain without joint inflammation |
| Bursitis |
Inflammation of fluid sacs near joints |
Normal vs. Abnormal State
Normal Joints: Smooth cartilage, full range of motion, no pain
Arthritic Joints: Inflamed, stiff, painful, possibly deformed
Types of Arthritis
| Type |
Description |
| Osteoarthritis |
Most common; cartilage breakdown due to aging |
| Rheumatoid Arthritis |
Autoimmune; affects joint lining |
| Psoriatic Arthritis |
Linked to psoriasis; affects skin and joints |
| Gout |
Uric acid buildup; sudden joint pain |
| Juvenile Arthritis |
Occurs in children; autoimmune |
| Ankylosing Spondylitis |
Affects spine and sacroiliac joints |
| Reactive Arthritis |
Triggered by infection |
Causes
Cartilage wear and tear
Autoimmune dysfunction
Genetic predisposition
Infection (bacterial, viral)
Metabolic disorders (e.g., gout)
Trauma or repetitive stress
Risk Factors
Age (especially >50)
Female sex (for RA, lupus)
Family history
Obesity
Joint injuries
Smoking
Sedentary lifestyle
Certain infections
Who Is Vulnerable/Susceptible?
Older adults
Women (especially for RA and lupus)
Athletes or laborers with joint stress
People with autoimmune conditions
Children (juvenile arthritis)
Complications
Joint deformity
Reduced mobility
Chronic pain
Fatigue and depression
Organ involvement (RA, lupus)
Increased fall risk
Work disability
Prevention
Maintain healthy weight
Exercise regularly
Avoid joint overuse
Quit smoking
Manage chronic conditions (e.g., diabetes)
Eat anti-inflammatory diet
How Condition Develops
Joint stress or immune dysfunction
Inflammation or cartilage breakdown
Pain and stiffness
Progressive joint damage
Reduced mobility and function
Common Symptoms
Joint pain and stiffness
Swelling and tenderness
Reduced range of motion
Warmth or redness
Fatigue
Morning stiffness (especially in RA)
Other Conditions That Can Mimic Arthritis
Fibromyalgia
Bursitis
Tendinitis
Lupus
Lyme disease
Osteoporosis
Diagnosis and Tests
Physical exam and history
Blood tests (RF, anti-CCP, CRP, ESR)
Imaging (X-ray, MRI, ultrasound)
Joint fluid analysis
Autoimmune panels
Treatment and Therapies
Medications:
NSAIDs (ibuprofen, naproxen)
Corticosteroids
DMARDs (methotrexate, hydroxychloroquine)
Biologics (adalimumab, etanercept)
Pain relievers (acetaminophen)
Non-Pharmacologic:
Physical therapy
Occupational therapy
Weight management
Assistive devices (canes, braces)
Surgical:
Joint replacement (hip, knee)
Joint fusion
Synovectomy
Statistics & Disparity
~53 million U.S. adults affected
Leading cause of work disability
Higher prevalence in women and African Americans
Underdiagnosis in rural and minority populations
Alternative/Complementary Treatment
Acupuncture
Tai chi and yoga
Massage therapy
Omega-3 supplements
Mindfulness and meditation
New Medications for Treatment
JAK inhibitors (e.g., tofacitinib)
IL-6 inhibitors (e.g., sarilumab)
Biologic DMARDs
Anti-TNF agents
Cost of Treatment and/or Management
| Item |
Estimated Cost (USD) |
| NSAIDs |
$10–$50/month |
| Biologics |
$2,000–$4,000/month |
| Physical therapy |
