Joints play a critical role in how we move, stay active, and maintain independence—but joint pain and arthritis can make everyday activities challenging. In this episode of Health Matters, host Courtney Allison speaks with Dr. Nana Sarpong, an orthopedic surgeon at NewYork-Presbyterian and Columbia, about how joints function and what happens when cartilage wears down. Dr. Sarpong explains the difference between mechanical osteoarthritis and inflammatory forms of arthritis like rheumatoid arthritis, including how each impacts joint movement, pain, and stiffness. The conversation covers conservative treatment strategies such as anti-inflammatory medications, physical therapy, bracing, and injections—along with when surgery becomes the right option. Dr. Sarpong also explains how modern joint replacement surgery works, how long implants now last, and what recovery looks like. Dr. Sarpong debunks common myths, including whether cracking your knuckles is harmful, if weather really affects joint pain, and the idea that people with arthritis should avoid movement. His key message: motion really is lotion—and staying active is essential for protecting your joints and preserving long-term mobility. Chapters 00:00 – What Are Joints and How Do They Work? An overview of joint anatomy, function, and why joints are essential to movement 04:30 – Arthritis and Joint Conditions The difference between osteoarthritis and inflammatory arthritis, causes of joint pain and stiffness 08:45 – Treating Joint Pain and Arthritis Conservative care, physical therapy, injections, and when surgery becomes the right option 12:00 – Protecting Your Joints and Busting Myths Exercise, weight management, common misconceptions, and the importance of staying active Key Topics Covered How joints function in the body Osteoarthritis vs. rheumatoid and inflammatory arthritis Causes of joint pain, stiffness, and cartilage loss Physical therapy and non-surgical treatments Joint replacement surgery and recovery Exercise recommendations for joint health Weight loss and joint load reduction Myths about cracking joints and weather-related pain Takeaway Message Joint pain doesn’t mean you should stop moving. Staying active, strengthening the muscles around your joints, and managing weight can help protect joint function and slow arthritis progression. When conservative treatments stop working, modern joint replacement surgery offers safe, durable solutions that can restore mobility and independence for decades.
