Platelet-Rich Plasma versus Corticosteroid Injection for Recalcitrant Lateral Epicondylitis: Clinical and Ultrasonographic Evaluation

To evaluate the clinical and ultrasonographic changes in the morphology and vascularity of the common extensor tendon after injecting platelet-rich plasma (PRP) or corticosteroid (CS) for recalcitrant lateral epicondylitis (LE).30 patients aged 18 to 60 years with recalcitrant (>6 months) LE not responsive to oral medication or non-invasive treatment were randomised to receive PRP (n=15) or CS (n=15) injection.
