If you have knee arthritis and you are carrying extra weight, you have probably heard that the new GLP-1 drugs could help. Dr. Schultz walks through what these medications do to the knee itself, not just the scale: the drop in load with every step, the effect on inflammation, and what the trials so far actually show about pain and function.

He also covers the questions patients ask him every week. Should you start one before surgery? Does it change your risk in the operating room? And could it mean some people never need a knee replacement at all? Honest answers, no hype, from a surgeon who does these operations for a living.
