Arthroscopic surgery is a minimally invasive procedure that can examine and operate on most diseases in the joint at the same time, and has obvious advantages over incisional surgery. Arthroscopy is more comprehensive than incision because almost all parts of the joint can be seen; it is more accurate than incision because the image is magnified, with an accuracy rate of 98%; the incision is small, only 4-6 mm, with little trauma and scarring, which does not affect the aesthetics; recovery is fast, with few complications, and in some cases, after anesthesia, the patient can move around, which is good for the patient’s confidence in overcoming the disease. In some cases, the patient can move around after anesthesia, which is a great benefit to the patient’s confidence in overcoming the disease; confirming the diagnosis of difficult joint diseases, and achieving immediate results for injuries that have plagued the patient for years. In general, there are few serious complications associated with arthroscopic surgery, but care should be taken to avoid wound infection. Swelling or accumulation of blood or fluid in the joint cavity within 2-3 weeks after surgery is a normal reaction and can be absorbed by puncture and drainage or physical therapy. Therefore, arthroscopic surgery is generally safe.
