ABSTRACT
To introduce the methods of the arthroscopy for exterior joint surgery, 45 cases have been subjected to surgical operations under arthroscopy in the exterior of joint during June 1999 to July 2002, including 14 for gluteus constrictor releasing by radiofrequency, 5 for removing of the screw and plate of the femur shaft, 3 for reduction and internal fixation for the fracture of humerus greater tubercle under the arthroscopy, 8 for removal of popliteal fosse cyst, and 15 for releasing carpal tunnel syndrome. The results showed that the function was satisfactory after reduction and internal fixation for humerus greater tubercle fracture, releasing of gluteus contracture and removing of popliteal fossa cyst by radiofrequency under arthroscopy. The symptoms of numbness and pain disappeared after carpal tunnel release by arthroscopy. No blood vessel and nerve injury, occurred and no recurrence and infection were found. In conclusion, the procedures of arthroscopy are with minimum invasion, less pain and easy for early rehabilitation for all treated cases. It can be used not only for joint disease but also be selective for the exterior joint surgery as well.
