Knee osteoarthritis

Knee pain and stiffness that is worse after rest or at the end of a busy day, often with a creaky or grinding feeling. It is very common from middle age onwards, and what an X-ray shows matches how the knee feels surprisingly poorly. Exercise is the first treatment recommended for it, at any age and any stage, because stronger muscles around the knee take load off the joint.

Also called knee arthritis, wear and tear in the knee, knee OA, stiff knee.

Does this sound like you?

  • Stiffness first thing in the morning or after sitting, easing within half an hour
  • Aching after a lot of walking, standing or stairs
  • A creaking or grinding feeling as the knee bends
  • It has built up over months or years rather than after an injury

This is not a diagnosis. Several things cause pain in the same place, which is why the list below matters.

Check these first: when it is not knee osteoarthritis

If any of these apply, get checked before you start the exercises. The ones marked in red can't wait.

  • Pain, swelling or tenderness in the calf. Get it seen the same day
  • The knee is suddenly hot, red and swollen, especially if you feel unwell
  • It locks, gives way or you cannot put weight on it
  • It is getting quickly worse, or pain keeps you awake at night

The exercises, in the order you would build them up

How long it takes

Most people notice less pain and easier stairs after six to eight weeks of regular strengthening, and it keeps improving for months. Some aching during and after exercise is normal and not a sign of damage, as long as it settles within a day.
