Event Description

It was reported that in the literature review "revision arthroscopic surgery after rotator cuff repair with a collagen graft: histologic evaluation of biopsy specimens from two patients"; a 49 years old female was treated arthroscopically 2 months post-injury for a partial-thickness rotator cuff tear on his right shoulder using a bioinductive collagen scaffold.The patient recovered well until five months postoperatively when she injured her right shoulder while lifting her fallen mother from the floor.The mri showed exuberant subacromial bursitis with diffuse synovial proliferation.Given the amount of subacromial fluid and concern for infection, an aspiration was performed that was negative for an infectious process after holding anaerobic cultures for 3 weeks.On re-evaluation three months later, her pain persisted, unrelieved by medical management, aspiration, and corticosteroid injection.A third mri was performed that demonstrated progressive improvement of the posterosuperior rotator cuff tendons with further decreased heterogeneity suggestive of continued healing.The patient underwent arthroscopic revision surgery, which showed abundant subacromial bursitis, adhesions, and fraying of the coracoacromial ligament.The subacromial space was debrided of adhesions.A subacromial decompression was performed.The histologic demonstrated complete integration of the graft with native tissue.On the initial two-week postoperative visit, the patient was recovering well with no reports of residual pain or loss of function.Her symptoms of bursitis, swelling, and pain at rest were resolved.
