Exercise Matches Anti-Inflammatory Drugs for Joint Pain

- Osteoarthritis affects more than 500 million people worldwide, driven by the gradual breakdown of articular cartilage, which lacks its own blood supply and therefore cannot repair itself effectively.
- Exercise distributes synovial fluid and its nutrients to cartilage while strengthening surrounding muscles, with a landmark Cochrane review finding it reduces pain and improves function in knee osteoarthritis comparably to anti-inflammatory drugs but without the same side effects.
- Proprioception declines with age, causing joints to bear weight unevenly and wear down faster, but walking on uneven terrain such as grass or gravel can help maintain the body's sense of position and movement.
- Balance-challenging exercises reduce fall rates by roughly 23%, per a systematic review cited by the author — significant because falls are the leading cause of injury-related death in adults over 65.
- Tai chi may be as effective as physical therapy for people with knee osteoarthritis, while swimming and water aerobics can support up to 90% of body weight to reduce joint strain.
- Quadriceps-strengthening exercises are particularly effective at reducing joint pain, according to research highlighted in the article, which also cites a 2026 study showing unstable-surface training significantly improves postural control in older adults.
Why it matters: For the more than 500 million people living with osteoarthritis, the evidence reframes exercise from a perceived risk into a frontline remedy — a Cochrane review found it matches anti-inflammatory drugs for knee pain relief without the side effects, while balance work cuts fall rates by roughly 23% in a population where falls are the leading cause of injury-related death after age 65.
