The objective of this chapter is to present a glimpse on the basics of elbow arthroscopy. Elbow arthroscopy can be used for multiple diagnostic and therapeutic interventions of the elbow. It involves the use of a 30° or 70° arthroscopic scope and multiple specially designed instruments to provide minimally invasive access to the elbow. Elbow arthroscopy can be used for debridement of septic arthritis, excision of osteophytes, excision of the radial head, removal of loose bodies, synovectomy, as well as treatment of chondromalacia, arthrofibrosis and joint contracture, and posterior impingement. Proper positioning of the patient is essential for successful elbow arthroscopy. Poor positioning can lead to difficult access and instrumentation, as well as a poor view of the anatomy, and can lead to an increased risk of injury and increased operative times. The skin should be cleaned with alcohol if needed, prior to surgical preparation. Multiple portals have been described in this chapter. These can be grouped into three main groups i.e. anteromedial portals, anterolateral portals and posterior portals.
