Can prolotherapy be a cure to patellar tendonitis? or platelet rich plasma? which is best?

Prolotherapy & PRP: Prolotherapy and PRP (platelet rich plasma) goals, in the case of patellar tendonitis, is to markedly reduce the tissue degeneration occurring within the patellar tendon at the time of injury. They decrease pain at rest, with daily activities, and during aggressive sports activities. It would be great if either one of these modalities was the cure all - not yet. Still more patients to be studied.

Hmnnn: In an 18 yr old the best tx for 'jumpers knee' or patellar tendinitis is rest from the offending activity , NSAID ( ibuprofen , etc) , hamstring stretching and ice massage. If symptoms persist despite above > 3-4 months then an MRI may be indicated. See an ORS w/ arthroscopy / sports medicine fellowship for evaluation. Best of Luck!
