Arthroscopic surgery is performed using microphotography and instruments placed at the end of a long, thin tube that is inserted into the joint through a small skin incision for intra-articular visualization. Through another small incision, instruments are inserted to repair joint damage and degenerative conditions. Arthroscopic procedures are most commonly performed on the knee, shoulder, elbow, hip, and ankle joints. The most common applications are knee meniscal tear repair, free body removal, patellar dislocation correction, anterior and posterior cruciate ligament injury reconstruction, multiple ligament injuries following knee dislocation, fixation of intra-articular ligament stop avulsion fractures, knee synovitis inflammation or injury, articular cartilage injury or intra-articular fracture, and some unexplained joint pain. Indications for shoulder arthroscopy include: adhesive capsulitis, shoulder dislocation, shoulder instability, acromioclavicular impingement syndrome, rotator cuff injury, greater tuberosity fracture of the humerus, and acromioclavicular dislocation. The procedure is performed under general or lumbar anesthesia, with the patient in a deep sleep and without pain, and the surgeon performs the procedure through several small incisions around the joint. A joint endoscope lens and other instruments are inserted into the joint. The surgeon uses the monitor to view the rest of the joint, then trims and removes the damaged tissue and repairs and reconstructs it. Arthroscopic surgery is becoming increasingly popular with doctors and patients because of its minimal invasiveness and quick recovery. Although arthroscopic surgery is a minimally invasive procedure, some patients often experience discomfort for a period of time after surgery. In addition, arthroscopic surgery requires fluid irrigation to ensure the surgical field of view, and saline is generally used, which can be irritating to synovial tissue. Due to these problems, patients may have some discomfort after surgery, and there are many individual differences between patients, which is why it takes some time to recover after surgery.
