Overview

Background Dupuytren’s contracture is a hereditary disorder which causes progressive fibrosis of the palmar aponeurosis of the hand, resulting in digital flexion contractures of the affected rays. Limited fasciectomy is a standard surgical treatment for Dupuytren’s, and the one with the lowest recurrence rate; however, the recurrence is still relatively high (2–39%). Adipose-derived stem cells have been shown to inhibit Dupuytren’s myofibroblasts proliferation and contractility in vitro, as well as to improve scar quality and skin regeneration in different types of surgeries. Autologous adipose tissue grafting has already been investigated as an adjuvant treatment to percutaneous needle fasciotomy for Dupuytren’s contracture with good results, but it was only recently associated with limited fasciectomy. The purpose of REMEDY trial is to investigate if limited fasciectomy with autologous adipose tissue grafting would decrease recurrence compared to limited fasciectomy alone. Methods The REMEDY trial is a multi-centre open-label randomised controlled trial (RCT) with 1:1 allocation ratio. Participants ( n  = 150) will be randomised into two groups, limited fasciectomy with autologous adipose tissue grafting versus limited fasciectomy alone. The primary outcome is the recurrence of Dupuytren’s contracture on any of the treated rays at 2 years postoperatively. The secondary outcomes are recurrence at 3 and 5 years, scar quality, complications, occurrence of algodystrophy (complex regional pain syndrome), patient-reported hand function, and hypodermal adipose tissue loss at 1 year postoperatively in a small subset of patients. Discussion The REMEDY trial is one of the first studies investigating limited fasciectomy associated with autologous adipose tissue grafting for Dupuytren’s contracture, and, to our knowledge, the first one investigating long-term outcomes of this treatment. It will provide insight into possible benefits of combining adipose tissue grafting with limited fasciectomy, such as lower recurrence rate and improvement of scar quality.
