Arthroscopic surgery Arthroscopic surgery is performed using microscopic techniques 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 disorders. There are many indications for arthroscopic surgery: most commonly in the knee, shoulder, knee meniscal tears, patellar dislocation, anterior and posterior cruciate ligament injuries, multiple ligament injuries following knee dislocation, knee synovitis, inflammation or injury, articular cartilage injuries or intra-articular fractures, some unexplained joint pain, etc. Shoulder dislocation, shoulder instability, acromioclavicular impingement syndrome, rotator cuff injury, humeral tuberosity fracture, etc. The surgery is performed under anesthesia and the surgeon performs the surgery through several small incisions around the joint. An endoscopic lens and other instruments are inserted into the joint. The surgeon looks at the rest of the joint through the monitor and then repairs and reconstructs the damaged tissue by trimming and removing the damaged tissue. Arthroscopic surgery is becoming increasingly popular with doctors and patients because of its minimal trauma and quick recovery.
