Arthroscopy surgery is much easier in comparison to 'open' surgery. Before the surgery, the patient will be given a general, local, or spinal anesthetic. The use of anesthetic varies on the basis of the joint problem. During the surgery, an incision of that of a size buttonhole will be made through which the arthroscope will be inserted. The doctor might make several other incisions to examine various other parts of the joint. To treat the injury, specially designed instruments are inserted through minute incisions to the joint. After the surgery, the incisions are covered through dressing. The doctor will advise you necessary post-operative tips and medications for recovery.
