General complications in arthroscopic shoulder surgery involve the risk of cerebral hypoperfusion, which is encountered more frequently in the beach chair position when compared to the lateral decubitus position. Optimal patient selection, patient positioning, monitoring and anesthesia minimize the risk for severe complications caused by cerebral oxygen desaturation.
Intraoperatively high blood pressure, insufficient equipment and vessel injuries may lead to poor visualization, which may even force the surgeon to convert to open surgery.
Early postoperative complications are often caused by severe pain, while infections are rare. Postoperative pain may be treated with adequate medication as well as nerve blocks.
Further postoperative complications are related to pain, weakness and stiffness of the shoulder. These complications are usually caused by sterile inflammation. If an infection is suspected, revision arthroscopy aids surgical debridement and gathering of tissue samples.
