The knee cap, also known as “patella”, is a triangular bone that guards the joints in the front of the knee. It is attached by ligaments to the muscles around the knee and increases mobility in the leg by acting as a support for the leg muscles. We highly recommend seeing our Knee Diagram for a better understanding of knee anatomy.
So, the next time you hit your knee, kneel down or bounce a soccer ball on your leg, thank your knee cap for being there to protect you.

Proper diagnosis of the knee is essential to determine the primary knee cap pain causes as well as providing the appropriate treatment for it. Here are some ways to diagnose knee cap pain:
- Physical examination by a physician to determine the location of the pain and evaluate for swelling, bruising, abnormal movement and other abnormalities within the knee.
- Magnetic Resonance Imaging (MRI Scan) or Knee x-ray to get accurate images for the knee condition particularly for dislocations or deformities.
- Ultrasound, CT or bone scans to photographically diagnose your knee.
- Drawer tests to detect a rupture of the cruciate ligaments in the knee.
Knee cap pain can be treated through:
- RICE therapy (Rest, Ice, Compress, Elevate). Rest the knee with the painful kneecap for at least a period of three days. Apply ice or cold pack to the injured kneecap to reduce inflammation and provide relief to the injured tissue. Compressing the affected kneecap with some knee brace, elastic bandage or even with a rag can help to relieve the pain and reduce the swelling. Elevate the injured leg to reduce the swelling or inflammation. To read more about the RICE method for injuries please click here.
- Medications – Over-the-counter prescription drugs to relieve the pain and reduce the inflammation and swelling.
- Knee brace, cast or splint – Braces can provide additional support and relieve pain.
