Treatment will depend on how severe the injury is. It can take weeks to months to heal. Medicine will be needed to ease swelling and pain. Other options are:
A mild fracture may be treated with a cast to keep the knee from moving as it heals. A brace, cane, or crutches may be needed after the cast comes off. Exercises will also need to be done to promote strength and movement.
Some people may need surgery if the patella is in pieces. Surgery may use pins and screws to put the pieces back together. Some people may need part or all of the kneecap removed, but this is not common.
Exercises will need to be done after surgery to promote strength and movement.
