Episode Details

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.
