Patients with preoperative fatty degeneration had worse outcomes after rotator cuff repair
Patients with large or massive rotator cuff tears who had intact tendons after arthroscopic rotator cuff repair experienced worse outcomes if they had preoperative fatty degeneration of the infraspinatus or subscapularis with Goutallier stage 2 or higher, according to results.
Among 155 patients with large or massive rotator cuff tears who underwent arthroscopic rotator cuff repair, researchers assigned 55 patients to either an unsatisfactory group or satisfactory group based on their University of California, Los Angeles (UCLA) score at final follow-up. The satisfactory group included 43 patients and the remaining patients were categorized in the unsatisfactory group.
Results showed a significant improvement in UCLA score from approximately 18.1 points preoperatively to approximately 29.8 points postoperatively among all patients. Researchers found no significant difference between the satisfactory and unsatisfactory groups with mean preoperative UCLA scores.
Patients’ preoperative Goutallier stage of the infraspinatus and/or subscapularis had a significant association with outcome, according to results of the multivariate analysis. Receiver operating characteristic curve analysis showed the infraspinatus and subscapularis had area under the curve values of 0.79 and 0.84, respectively. Researchers noted these findings reveal Goutallier stage 1 as the cutoff value to predict an unsatisfactory result in both muscles. – by Casey Tingle
