At 24 weeks, clinically meaningful improvements were found in patients treated with leukocyte-rich PRP compared to active controls.
These 230 patients had already failed at least 3 months of conventional therapy. A successful treatment was defined as 25% or greater improvement on the visual analog pain scale. At 12 weeks, the differences between groups were not significant.
At 24 weeks, those treated with LR-PRP had improved pain scores and less elbow tenderness. The benefit of PRP is not immediate.
