|
Purpose: To evaluate the influence of progressive fatty degeneration of the rotator cuff (shown on MRI after rotator cuff repair) on the clinical outcome.
Materials and Methods : At one-year postoperatively, 25 patients with progressive fatty degeneration on MRI were evaluated using the American Shoulder and Elbow Surgeon Standardized Assessment Form (ASES) score and the Constant score.
Results: Average ASES scores were 57.76±17.0 preoperatively, and had significantly increased to 84.8±11.9 at 1-year postoperatively, and to 92.7±7.7 at final follow up. Average Constant scores were 56.2±2 preoperatively, and had increased significantly to 78.2±11.7 at 1-year after surgery, and to 83.1±7.9 at final follow-up. All cases except 1 showed satisfactory results. Groups that showed re-tears, large tears or fatty degeneration on infraspinatus showed inferior results to those without these developments.
Conclusion: On average 37.4 months of follow-up, clinical outcomes had improved in 96% of patients with progressive fatty degeneration of the rotator cuff. Therefore, progressive fatty degeneration on MRI at 1 year after rotator cuff repair does not influence final clinical results.
