A trauma to the knee’s bones, ligaments, tendons, bursae, meniscus, or articular cartilage can cause pain and swelling. Serious injury can cause blood to flood into the knee joint, leading to significant swelling, warmth, stiffness, and bruising.This condition is called « haemarthrosis » and can warrant urgent medical care.
In many cases, a mild to moderately swollen knee may be treated at home. A doctor should be contacted if:
1 The knee is severely swollen or has a pronounced abnormality
2 The knee cannot fully straighten or flex
3 The knee is severely painful (e.g. the pain is not adequately treated with over-the-counter medication)
4 The person cannot bear weight on the knee, or feels as if
5 the knee is going to « give out »
6 The skin over the knee turns hot or red
7 The person has a fever of 100.4 or higher
8 Swelling has been present for 3 or more days
How to manage a mild to moderately swollen knee❓

I= Icing 3 to 4 times a day for 20 minutes at a time
C= Compressing the knee with an ace bandage to prevernt further swelling
