Tommy John surgery


 

Tommy John surgery, known by doctors as ulnar collateral ligament reconstruction (or UCL), is a surgical procedure in which a ligament in the medial elbow is replaced with a tendon from elsewhere in the body (often from the forearm, hamstring, or wrist of a cadaver). The surgery is named after Tommy John, a pitcher for the Los Angeles Dodgers who was the first professional athlete to successfully undergo the operation in 1974. The procedure was performed by Dr. Frank Jobe.
