tenodesis and subaromial impingement surgery on 02/04/14 and have been in severe pain every since. post-op MRI says now i have a partial-thickness articular-sided tear at the juction of the sistal supraspinatus and infraspinatus tendons.. my surgeon says he only used a button and not a screw for the tenodesi. surgeon told me he did not notice Any rotator tears at all.. very severe pain and can not lift my right arm even after 13 weeks of post post op rehab. I have tried PT but the pain doing the exercised is unbearable. The MRI report also states : Icreased STIR signal surrounding the tenodesis screw (button) could be artifactual or may be related to granulation tissue and /or loosening. This abnormality could be further assesed with CT. ?? thank you-wating for answer
