What on earth is prolotherapy?

Question

It's supposed to rebuild your knee, the add says.

Answer 1

Prolotherapy is a "natural" treatment where a substance is injected into a painful area to help speed up the body's healing process.

The decision to try it is yours but keep in mind that natural products do not go through the stringent testing of the FDA so they can claim anything they want with no proof to back it up. Since there is also no testing, there is no documented information such as failures or side effects.
