While the lining is swollen, it releases enzymes that eat away at your cushion. Bits break loose, your knee treats them as a threat, and the lining swells even harder.
This is the Swelling Loop.
Every time it goes round, your knee gets a little worse. That's why it doesn't just hurt. It gets worse every year.
👉 That's why painkillers, injections and joint tablets often fail. Painkillers dulled the loop. Injections paused it. Joint tablets tried to rebuild what it kept eating. None of them calmed the swollen lining, so as soon as they wore off, the loop carried on.
So if nothing has lasted, that's not on you.
