In Osteoarthritis, the glucosamine/chondroitin combination is ONLY effective in which joint?

• A. Knee
• B. Hip
• C. Hand
• D. Spine

Answer: (A)

The key idea is that the effectiveness of glucosamine and chondroitin varies by joint, with the knee showing the most consistent, though modest, symptom relief. In knee osteoarthritis, some high-quality studies and meta-analyses report small improvements in pain and function compared with placebo, suggesting a modest benefit for many patients. However, the same combination has yielded inconsistent or no meaningful improvement in other joints. For hip osteoarthritis, results are variable and often show little benefit; in hand osteoarthritis, evidence is sparse and inconsistent; and for spine-related OA, there is little solid data demonstrating a real clinical advantage. Because the strongest, more consistent signal for benefit is seen in knee OA, this joint is considered the one where glucosamine/chondroitin is most likely to be effective.
