The outlook depends on many factors, including the severity of your shoulder injury, your age and your participation in athletic activity. For example, if you are a teenaged athlete and you play contact sports, such as football or hockey, after a shoulder dislocation, your overall risk of a second shoulder dislocation may be as high as 90%. Repeat injury may make your shoulder unstable enough that it needs to be repaired with surgery. Surgery usually restores the shoulder's stability and reduces the risk of future dislocation to 5% or less.
If you are an adult and have an uncomplicated shoulder dislocation, your risk of a second dislocation is low, with repeat dislocations occurring only about 25% of the time for people in their 30s and even less often for older age groups.
