A doctor will examine the knee, check how deep the swelling goes and make sure the joint itself is not involved before deciding how to treat it.
If it is a cyst or abscess, the area is numbed, a small opening is made and it is drained. Any sac or pocket is cleaned out so the swelling does not return.
After treatment the knee is dressed with gauze and should be rested for a day or two. Keeping the dressing clean and dry helps it heal without infection.
Cleaning scrapes on the knees right away, wearing knee protection when kneeling for work and not squeezing bumps all help prevent problems like this.
Keep your balance and take it one step at a time. The videos below show cysts and abscesses being treated by professionals.
