Arthroscopic Xenograft Repair of Massive, Irreparable Rotator Cuff Tears

Abstract: Purpose: Our purpose was to assess the short-term results of arthroscopic bridging repair of massive, irreparable rotator cuff tears by use of a Permacol. Materials and Methods: Between October 2010 and April 2011, 6 patients with massive, irreparable rotator cuff tears were treated with arthroscopic bridging repair using a Permacol. All were evaluated preoperatively and postoperatively by use of the Korean Shoulder Scoring System (KSS). Magnetic resonance imaging was performed postoperatively at mean 4.2 months (range, 2 to 10 months) after operation. Results: At a mean follow-up of 7 months (range, 4 to 12 months), the mean KSS increased significantly from preoperatively mean 53.0 to postoperatively mean 72.3 (p=0.046). Statistically insignificant improvements were seen in pain (p=0.066) and range of motion (p=0.336). As documented on magnetic resonance imaging, there were two patients with full incorporation of the graft into the native tissue, 1 partial retear, and 3 complete retear. There were no complications such as adverse inflammatory or septic joint in these patients. Conclusion: Although Permacol, porcine dermal xenograft may be effective in other areas of the body for tendon healing, its use in bridging repair of massive, irreparable rotator cuff tears seems to have to be chosen prudently and warrants further evaluation.

Calcific Tendinitis of Shoulder Associated with Intraosseous Involvement: A Case Report

Abstract: Purpose: We present an atypical case of calcific tendinitis of the shoulder with intraosseous loculation. Materials and Methods: A 59 year-old female complained of acute exacerbation of chronic left shoulder pain and restricted range of motion. Simple radiographs showed a subacromial calcific deposit and magnetic resonance imaging revealed cortical erosion with intraosseous extension of calcific material mimicking infection or tumor. She was managed with arthroscopic excision of the calcific deposit, curettage of the intraosseous lesion and subsequent rotator cuff repair with a suture anchor. Results: Her acute pain promptly subsided. Her rehabilitation was uneventful and she gained full range of motion. Radiographs five months after the operation showed no recurrence of calcific material. Conclusion: Calcific tendinitis of the shoulder can present with a variety of images involving the adjacent bone. The correct recognition of this disorder may avoid unnecessary investigation and treatment.
