Lateral epicondylitis is one of the most common pathologies of the elbow joint. It is a painful condition characterized by angiofibroplastic hyperplasia around the wrist extensor muscle group. Although it is a self-limiting disease, 8-10% of patients require surgical treatment. Classical surgical treatment can be performed percutaneous and open. Arthroscopic treatment has started to attract attention after 1999. Arthroscopic lateral epicondylitis treatment has become an important option among other treatments, thanks to the fact that arthroscopic anatomy is better learned by time and functional scores reach satisfactory levels. Arthroscopic lateral epicondylitis surgery requires a very good knowledge of neurovascular and three-dimensional elbow anatomy. There is a very narrow joint and important nerves and vessels running along its periphery. Therefore, the locations of the portals in elbow arthroscopy were determined according to neurovascular and musculotendinous anatomy. Considering the intra-articular projection of the anatomical structures, the surgical plan is created from the inside of the joint to the outside. Anatomical localization of the pathology is an important advantage for this surgical approach. Both meta-analyses and randomized controlled studies show that arthroscopic lateral epicondylitis debridement can provide high functional scores and patient satisfaction.
