Elbow arthroscopy surgery is performed by making small (1-2 cm) incisions in the sides and back of the elbow, filling the elbow joint and continuously flushing it with sterile fluid to allow a small camera to be inserted to view the inside of the elbow.  A variety of specialized tools are then placed into the elbow joint to remove loose bodies or address any cartilage or ligament injuries.  Elbow arthroscopy is in contrast to open elbow surgery, where a larger incision is made in the skin and joint capsule (thick fibrous tissue surrounding the joint) in order to access the joint.  Smaller incisions and less dissection of the joint capsule allows for quicker recovery and generally less pain after surgery. Physical therapy is recommended after nearly all arthroscopic surgery of the elbow to facilitate return of normal motion, strength, and function. The duration of PT and the timing of return to full activity depend on the exact surgery performed.
