Lateral Epicondylitis or tennis elbow is one of the most commonly diagnosed upper-extremity musculoskeletal disorders seen in general practice. It is characterized by painful enthesopathy or tendinosis of the common extensor tendon at the outer region of the elbow at the fibro-osseous junction. "Although tennis elbow" was originally made note of in the medical literature by Runge in 1873, the term derives from "Lawn Tennis Arm" later described by Morris in 1882.
