Purpose: To describe the technique and short-term results of arthroscopic repair of irreparable rotator cuff tears using a GraftJacket® allograft. Although current rotator cuff repair techniques offer excellent results in most cases, there are still many instances where tendon repair is not possible. Allograft substitutes offer the advantages of saving bone stock, while maintaining anatomic integrity within the shoulder. Materials and Methods: Between March 2003 and February 2004, 16 patients with massive, contracted immobile rotator cuff tears were treated with arthroscopic placement of a GraftJacket® allograft by a single surgeon. Patients were followed for 1-2 years. All were evaluated preoperatively and postoperatively using the modified University of California Los Angeles (UCLA) scoring system, Constant score and Simple Shoulder Test. MRI was performed postoperatively at 3 months and 1 year. Results: At mean follow-up time of 26.8 months (range, 12-38 months), 15 of 16 patients were satisfied with the procedure. The mean UCLA score increased from 18.4 preoperatively to 30.4 postoperatively ( P = 0.0001). The Constant score increased from 53.8 to 84.0 ( P = 0.0001). Statistically significant improvements were seen in pain, forward flexion and external rotation strength. Thirteen displayed full incorporation of the graft into the native tissue, as documented on magnetic resonance imaging. There were no complications in this cohort of patients. Conclusions: Our study supports GraftJacket® allograft as a viable solution for surgical salvage in select cases of massive irreparable rotator cuff pathology.
