What if worn-out parts of your body didn’t need to be replaced just regenerated?

Stanford researchers recently published work showing cartilage lost to aging or arthritis can be regrown, using either an oral drug or a local injection.

If this translates to humans, it could make knee and hip replacements unnecessary.

Millions of people undergo major joint replacement surgery every year.
Regenerating cartilage instead of replacing joints would mean less pain, lower cost, and far better outcomes.

That future may be closer than we think.
