Regenerative medicine: Helping the body heal itself

It sounds like science fiction, but researchers today are unlocking the body's natural healing ability as part of an emerging field of science called regenerative medicine. Although the field is relatively young, some regenerative treatments are already approved to help repair joints and relieve pain, allowing some patients to avoid surgery altogether. Two leaders in the field detail their research into current and future clinical applications within orthopedics.  Kenneth Zaslav, MD, is director of The Center for Regenerative Orthopedic Medicine at Northwell/ and part of the Lenox Hill Orthopedic Institute  Seth Sherman, MD, is a sports medicine and orthopaedic surgeon at Stanford Health Care.  Learn more about Northwell Health's Center for Regenerative Medicine.
