Medial epicondylitis and lateral epicondylitis are among the most common elbow pathologies affecting people aged between 40 and 50 years.

Although epicondylitis is often a self-limiting condition that improves with conservative treatment, the condition can be difficult to eradicate.

The purpose of this study was to compare the effectiveness of platelet-rich plasma (PRP) injections and ultrasound-guided percutaneous tenotomy (Tenex) for the treatment of medial or lateral epicondylitis.

Our hypothesis was that the Tenex procedure would not be inferior to PRP injections in the treatment of medial or lateral epicondylitis.
