Steps to create Web camera arthroscope. (A) Camera with Universal Serial Bus (USB) cable exiting from the rear of the casing. (B) Water pipe cut into 2 halves (25-cm-long and 15-mm-diameter rigid plastic water pipe). (C) Small cut opposite the camera about 5 cm from the end. This is where the cable of the camera exits. Electrical tape is used to reunite the 2 halves of the pipe. Tape should be wrapped around the pipe in a continuous fashion starting from the camera end. When one is approaching the cut, he or she should pull firmly on the camera cable exiting from the cut and wrap the tape around it. (D) Camera with tilt relative to the pipe, imitating the arthroscope's field of view. (deg, degrees.)
