Fat cells from your tummy could fix your creaky knees: Five-a-side footballer John explains how injections taken from his abdomen helped end his joint pain

THE PATIENT

For most of my life I’ve been active and I played five-a-side football a few times a week for 16 years. But in August 2016 I suffered a sudden shooting pain inside my right knee while at work.

This was followed by a feeling of heat deep inside the knee that didn’t go away.
