This study investigates the outcomes of 1106 patients with Dupuytren's disease treated with limited fasciectomy or percutaneous needle fasciotomy over 16 years according to the different domains of patient-reported hand function. These patients completed the Michigan Hand Outcomes Questionnaire before and 3 months after surgery. Scores for the various outcome parameters were calculated and linear regression analyses were used to examine associations between the changes in digital extension deficit and change in Michigan Hand Outcomes Questionnaire (sub)scores. We found the largest effects of surgical treatment in the decreases in extension deficit, the appearance of the hand, and the satisfaction with the hand function. However, associations between different domains of evaluation were weak. We conclude that improvement of digital extension deficits is not parallel to varying aspects of patient satisfaction. The findings underline the importance of assessing domains relating to patient satisfaction other than objective hand function measures in Dupuytren's disease. Level of evidence: IV.
