Summary

This study tested whether injecting collagen into the heel can safely ease pain from chronic plantar fasciitis. Sixty adults who had not improved with other treatments received either collagen or a placebo injection. Researchers measured pain levels and heel thickness over 12 months to see if collagen worked better than placebo.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
collagen injection
What this could lead to
If it works, this could offer a new treatment option for people with stubborn heel pain that hasn't improved with other therapies.
What could go wrong
This is a small, completed study with only 60 participants. The results may not apply to everyone, and collagen injections may not be more effective than placebo.
