What is the most prevalent skeletal problem in the United States?

• A. Osteoarthritis
• B. Stress fractures
• C. Osteoporosis
• D. Gouty arthritis

Answer: (A)

Osteoarthritis is the most common skeletal problem because it affects a larger share of the population than the other conditions listed. It’s a degenerative joint disease that increases with age and higher body weight, leading to cartilage wear, changes in the bone beneath the cartilage, and bone spur formation. This combination produces chronic joint pain, stiffness after periods of rest, and functional limitations across major joints like the knees, hips, and hands. Because OA affects so many people—often chronically—its overall prevalence in the United States surpasses that of osteoporosis (which, while common, is frequently asymptomatic until a fracture occurs), gouty arthritis (less prevalent in the general population), and stress fractures (more sporadic and risk-specific).
