About

Lateral epicondylitis (LE) is the tendinopathy of the common extensor tendon. Although exact etiology remains unclear, it is believed to be caused by overuse.

Even though, genetics factor related to tendinopathies were defined accompanying tendinopathies in patients with LE is yet to be studied.

Madrid sonographic enthesitis index (MASEI) is an ultrasound based scoring system, developed for the evaluation of the enthesitis. Initially developed for ankylosing spondylitis, its usage has also become widespread in other musculoskeletal diseases.

The aim of this study is to calculate the MASEI score in patients diagnosed with LE, and compare it to healthy volunteers.
