The best outcomes of rotator cuff repairs come from a variety of factors. Personal factors, like the location and extent of the repair, as well as the patient’s age and overall health play a big role in success rates. Surgical technique choice and length of time spent in a sling following do not play as big of a role. What you can do to help make your repair successful is to follow the instructions of your surgeon and physical therapist, respect the healing times (wear your sling!), and have patience with your recovery.
