Varies Widely. As with all things the duration and details of the procedure really depend on the level of skill and experience of the surgeon as well as the extent of pathology. You can learn more here: http://theshouldercenter.Com/unstable-shoulder.Htm.
60 minutes. Generally, an arthroscopic bankart takes 60 min, sometimes longer. However, the effects of anesthesia will make it feel like the blink of an eye.
