Does leucocyte concentration have a role in the outcome of PRP therapy for lateral epicondylitis – A randomized controlled trial

A B S T R A C T
Background: Of late the leucocyte concentration in the platelet-rich plasma (PRP) therapy for lateral epicondylitis has gained importance. We aimed to evaluate the effects of leucocyte concentration in the outcomes of the PRP used for lateral epicondylitis. Materials and Methods: This is a double-blinded randomized controlled trial conducted on patients having lateral epicondylitis comparing the pain relief and functional effects of leucocyte-poor PRP (LP-PRP) and
leucocyte-rich PRP (LR-PRP) at one, three, six, and twelve months post-injection using the Visual Analog
Scale (VAS) for pain and Mayo Elbow Performance Score (MEPS) for function.
