Surgery for a dislocated shoulder can be done with the traditional large incision or arthroscopically, using very small incisions and long surgical instruments to reach the area to be repaired. Both types of surgeries have their pros and cons.
Traditional surgery generally takes longer to recover from because of the size of the incision and the type of work the doctor does while inside the shoulder. There is a higher risk of complications and longer time in hospital, but the success rate seems to be a bit better than that of arthroscopy. On the other hand, arthroscopic surgery generally requires a shorter recovery time, meaning shorter hospital stay, and fewer complications. However, there is a higher risk of redislocating the shoulder, according to some study findings.
You should discuss this with your doctor, weighing the pros and cons of both types of surgeries.
