Walking May Be Key to Reducing Knee Osteoarthritis Pain, New Study Finds
A new study published today indicates that regular aerobic exercise, such as walking, can significantly reduce pain, improve movement, and enhance the quality of life for individuals suffering from knee osteoarthritis, offering a potential non-pharmaceutical approach to managing the condition.
The research, published October 15 in The BMJ, analyzed data from 217 randomized controlled trials involving over 15,000 participants worldwide. Researchers found that aerobic exercise consistently provided the greatest benefits across various outcomes. “Aerobic exercise consistently showed the greatest benefits across almost all outcomes,” said Dr. Lei Yan, the study’s first author, a doctoral student at the Johns Hopkins University School of Medicine. Approximately 54 million adults in the United States – roughly 1 in 5 – are affected by some form of arthritis, with osteoarthritis being the most prevalent.
Experts emphasize the importance of low to moderate-impact activity. “You don’t have to aim immediately for 10,000 steps a day,” explains Dana Santas, a certified strength and conditioning specialist. “For patients just starting to exercise, walking or cycling for five to 10 minutes a day can help you get started.” It’s crucial to avoid high-impact exercises like running or deep squats, and to properly warm up before activity. Understanding the mechanics of the knee joint is also important; as Dr. Santas notes, ensuring the knee isn’t forced into unnatural movements can prevent further issues.

While exercise is a key component, other treatments for osteoarthritis include acupuncture, weight loss, anti-inflammatory supplements, and physical therapy. Dr. Antonia F. Chen, chair and professor of orthopedic surgery at the University of Texas Southwestern Medical Center, notes that osteoarthritis is a leading cause of chronic disability, impacting an estimated 80% of adults over 55. Researchers stress that consistency is vital, and patients should consult with their doctor before beginning any new treatment plan.
Researchers will continue to investigate optimal exercise regimens and explore personalized approaches to managing knee osteoarthritis, with the goal of improving long-term outcomes for patients.
