We compared the functional outcomes, health-related quality of life, and satisfaction in diabetic and non-diabetic patients undergoing A1 pulley release for trigger finger in 192 patients. Preoperative and postoperative Quick Disabilities of the Arm, Shoulder and Hand questionnaire (Quick DASH), EuroQol-5 dimensions, and satisfaction scores were collected prospectively over a 6-year period. These patients had a mean follow-up of 14 months (range 11-40) after surgery. There were 143 patients (143 trigger fingers) without diabetes and 49 patients (49 trigger fingers) with diabetes. We found overall QuickDASH improvement was the same in both groups (-4.5 points). Patient satisfaction rates were comparable in both groups (90% versus 96%), and no significant difference in postoperative health-related quality of life was observed. No complications were reported in either group. We conclude from this study that A1 pulley release leads to similar functional improvement and high patient satisfaction at one year postoperatively in diabetic and non-diabetic patients.: III.
