Treatment algorithm for failed rotator cuff tear. With persistent pain or loss of function for more than 6 months an MRI should be performed. Based on the Sugaya classification [2] tendinopathy and retear are differentiated. Non-operative treatment for tendinopathy should include eccentric exercises to promote tendon healing. When a retear is confirmed, surgical options are evaluated. If surgery is not favourable, pillars for non-operative treatment are compensation, adaption, and patient education.
