Summary

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.

Conditions

• Lateral Epicondylitis
• Lateral Elbow Tendinopathy (Tennis Elbow)

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Madrid Sonographic Enthesitis Index	Patients will be evaluated with ultrasound at 6 different locations on each side, for total of 12 locations. These will be insertion points of triceps brachii tendon, quadriceps tendon, proximal and distal patellar tendons, achilles tendon and the plantar fascia. Evaluation parameters are the structure and thickness of the tendon, the presence of calcifications or enthesophytes, erosions in the bone, regional bursitis, and the presence of power-Doppler signal in the entheses.
