Things you might see, hear, or feel


Swelling is common. Some people with OA have swollen knees all the time. For some people the swelling comes and goes. Swelling does not mean you have damaged your joint. If you have sudden or tense (tight) or hot swelling, you should see your doctor.


It is normal for knees to be noisy at any age. Noises are not a big deal. Noises do not mean you are causing damage. Don’t worry about noises unless you are getting a lot of pain with each one. Don’t let them stop you moving.


Knees with OA often look different. This can be due to bony swelling, or changes in leg muscles or knee shape. These changes happen as your body adapts to OA and do not mean there is a problem.


It is normal for your knee to seize-up from time to time. If your knee locks and you cannot overcome this, you should see your GP.


Giving way or sudden weakness is common when you have OA. Improving muscle strength around the knee with exercise will help. See your GP if you are worried.


Joints with OA can feel a bit stiff. Most of the time, the best thing to do is move the joint more.
