Role of Ultrasound Guided Platelet-Rich Plasma (PRP) Injection in Treatment of Lateral Epicondylitis

Abstract

Background: Lateral epicondylitis is referred to a degenerative disorder that affects the common extensor tendon (CET) where it attaches to the lateral epicondyle of the humerus. Nowadays, one of minimally invasive interventions is platelet-rich plasma (PRP) injection that had been explored in some controlled clinical studies to show its effectiveness in treating lateral epicondylitis through inducing inflammation rather than suppressing it.

Objectives: The aim of our study was to investigate the effectiveness of ultrasound guided platelet-rich plasma (PRP) injection in treating chronic lateral epicondylitis in addition to identifying the potential sonographic morphological changes in the common extensor tendon (CET) after PRP injection.

Results: Statistical analysis showed high significant improvement in all ultrasound findings of common extensor tendon (CET) including echotexture, thickness, cross section, partial tear and calcification in majority of patients.

Conclusion: We concluded that US-guided platelet-rich plasma (PRP) injection for treatment of lateral epicondylitis was a safe, minimally invasive and effective procedure in improving the sonographic and pathological changes of common extensor tendon (CET).
