What can i do to get rid of patellar tendonitis(jumper's knee)?

Let me help: Apply cold therapy on a regular basis, especially after any form of exercise. Wear a knee support, or jumpers knee strap to reduce pain and ease the strain on the tendon. See a sports injury specialist who can apply sports massage techniques to the tendon and advise on a rehabilitation program. Eccentric strengthening is usually recommended. If that did not do, may be you need surery.

Inflammed tendon: Typical treatment options consist of rice, antiinflammatories (oral, topical, injected), physical thearpy (strengthening and stretching), counterbraces, massage, injections (cortisone or prp)...
