A 38-year-old woman presented with a traumatic tear of her right supraspinatus measuring 1.2 cm in length and 8 mm in transverse diameter. It was repaired arthroscopically using a double row suture anchor technique. A metallic FASTIN suture anchor with orthocord (Depuy Inc. USA) was used initially followed by the Quick-T anchor fixation system (Smith & Nephew Inc Switzerland). The initial post-operative procedure was uneventful. The patient's shoulder was mobilized at six weeks. The patient started complaining of pain on abduction. This was initially treated with analgesics but when the patient did not settle the shoulder was examined using ultrasound. This showed inflammatory changes in the subacromial space and was inconclusive. The intra-operative photographs of the repair did not show any abnormality or evidence of impingement syndrome. The patient was taken back to theatre for diagnostic arthroscopy of the shoulder which showed the button of the Quick-T anchor lying vertically in the subacromial space rubbing the undersurface of the acromion ([]). This was removed using a shaver without compromising the repair. Subacromial decompression was not required as there was no other evidence of impingement. Postoperatively the pain completely resolved. At follow-up three months after the second arthroscopy, the patient had full-range shoulder movement and pain was no longer present.
