I work as an emt 12 hrs a day with the patellar tendonitis. any reccomendations?

Patellar Tendinitis: Treatment options include nsaids (oral or topical), ice, brace use (chopat patellar tendon strap), and exercise modification. Specifically, eccentric or negative quad contractions have been shown to be particularly helpful. You could see a physical therapist to help you with all of this as well as try other modalities such as ultrasound.

RICE: Unfortunately your job probably has you repetitively kneeling and on your feet quite a bit which may exacerbate an already existing tendinitis. Ideally you want to rest from the repetitive activity but if you cannot then you may want to consider a pt program to balance the patellar tracking mechanism in addition to a patellar band, orthotics, and an anti-inflammatory (if tolerated).
