The researchers conducted a literature review of 18 randomized controlled trial studies that used autologous blood, platelet rich plasma, platelet poor plasm or autologous conditioned plasma to treat tendinopathy. They analyzed patients’ changes in pain intensity outcomes based on preparation method and injection technique.
Here’s what you need to know:
1. Those treated with highly cellular leukocyte-rich platelet rich plasma — including the GPS kit, MyCells kit and Prosys kit — experienced the most significant benefits in pain intensity.
2. When leukocyte-rich platelet rich plasma system types were grouped together, there was an especially strong positive effect in comparison to leukocyte-poor platelet rich plasma.
3. In the control groups, there was no significant difference between different types of injections. These control injections included saline, local anesthetic, corticosteroid and dry needling.
The researchers conclude that there is “good evidence to support the use of a single injection of LR-PRP under ultrasound guidance in tendinopathy.”
