Arthroscopy is a minimally invasive surgery whose main purpose is to examine the disease in the joint through arthroscopy and to treat it accordingly. Therefore, arthroscopic surgery is less harmful to people, but there is always a tiny damage, and there is always a certain impact on the human body, as follows: 1. Arthroscopic surgery requires two small holes to be opened in the front of the joint, and a 4mm thick arthroscope is put in for examination, and some very special patients also need to make additional lateral incisions, so arthroscopic surgery will leave some very small incisions in the periphery of the joint afterwards. incision; 2. Most of the joint diseases themselves are more serious and difficult to diagnose, so when arthroscopy is chosen, he will be given joint cleaning and synovectomy. After arthroscopic surgery, swelling of the joints and even synovial effusion can occur because of the large amount of saline infusion needed to expand the joint cavity; 3. Some patients who are particularly pain-averse may experience joint stiffness or even difficulty in moving if they cannot undergo early training. Overall, the hazards of arthroscopic surgery are relatively small and basically negligible.
