Adam Cohen is an orthopedic surgeon with expertise in sports medicine. In this episode, Adam breaks down the anatomy of the lower extremities: the hip, knee, ankle, and foot. He explains in detail the common injuries, sources of pain, and what leads to the development of arthritis.

The discussion includes various procedures like hip replacement, knee replacement, ACL reconstruction, repair of meniscus tears, and more.
