What should I do if I have a knee cap injury?
There should be a particular focus on strengthening the muscles directly around the kneecap, the VMO muscles as they hold the patella in the centre of the groove and the gluteal muscles to improve the control around the patella – see the kneecap exercises section.
What is the bone in front of the knee called?
Knee cap or patella is a triangular rounded bone present in front of the knee. It is formed because of friction between the quadriceps (muscle group on front of thigh, which helps in knee straightening or extension) tendon and the knee joint.

Knee bursitis: Pain, swelling, and warmth in any of the bursae of the knee. Bursitis often occurs from overuse or injury.
What is the muscle above your knee cap?
The upper part of the patellar tendon attaches on the lower part of the knee cap, and the lower part of the patella tendon attaches to the tibial tubercle on the front of the tibia. Above the knee cap the quadriceps muscle via the quadriceps tendon attaches to the top of the knee cap.
What is your knee cap also known as?
