Platelet-rich plasma: new clinical application: a pilot study for treatment of jumper's knee

Injury. 2009 Jun;40(6):598-603. doi: 10.1016/j.injury.2008.11.026. Epub 2009 Apr 19.


This study describes a simple, low-cost, minimally invasive way to apply PRP growth factors to chronic patellar tendinosis; 20 male athletes with a mean history of 20.7 months of pain received treatment, and outcomes were prospectively evaluated at 6 months follow-up. No severe adverse events were observed, and statistically significant improvements in all scores were recorded. The results suggest that this method may be safely used for the treatment of jumper's knee, by aiding the regeneration of tissue which otherwise has low healing potential.
