Shoulder Arthroscopy is a basic procedure in which a 4.5 mm arthroscope (telescope) is introduced into the shoulder joint through a small puncture portal at the back of the shoulder. A comprehensive examination and testing of each structure of the joint are performed. The head of the Humerus (the arm bone), the glenoid (shoulder blade forming the cup), the biceps, subscapularis muscle, the rotator cuff, and the ligaments both in front and back of the shoulder are commonly examined. This assists in diagnosing common problems such as early arthritis of the shoulder, infective arthritis (septic lesions), Rheumatoid arthritis, biceps tear, SLAP lesions, Rotator cuff lesion, impingement syndrome, ligament tear, recurrent dislocation of the shoulder (Bankart lesion), instability, hyperlaxity, labral tear and cyst, Hills-Sachs lesion, Frozen shoulder, loose body, bursitis, tendonitis, etc.
