The knee that won’t settle
Six weeks after a twist and it still swells after a walk. Why rest alone rarely fixes it, and what does.

Most of the knees we see have one thing in common: they were rested. Carefully, sensibly, for weeks. And they still swell after a walk to the shops.
Why rest stops working
Rest is right for the first few days after a twist. After that, a knee that is never asked to do anything gets worse at doing things. The muscles around it weaken within days, the joint loses some of its range, and the first real walk becomes a bigger load than it was before you got hurt. The swelling afterwards is not a sign of new damage. It is a knee saying: that was more than I am used to.
What we do instead
We find the load the knee can take today without swelling the next morning, and we start there. For some people that is ten slow step-downs from the bottom stair. For others it is a 20-minute walk. Then we add a little each week, and we watch the morning after, not the moment itself.
Three things make the biggest difference:
- Slow strength work for the thigh and the hip, two or three times a week.
- A walking plan that grows by about ten percent a week.
- A rule for bad days: if it swells more the next morning, go back one step, not to zero.
When to see someone
If your knee locks, gives way, or swells within an hour of an injury, see your GP or a sports physician first. Otherwise, if it has not settled in three weeks, book a physiotherapy intake. Bring the shoes you walk in.
