Long Term Clinical Outcome After Arthroscopic Rotator Cuff Repair Augmentation With Autologous Microfragmented Lipoaspirate Tissue

Specific Aims : The aim of this prospective randomized controlled single-blind clinical trial was to evaluate the safety and efficacy of autologous microfragmented lipoaspirate tissue in arthroscopic rotator cuff repair. The primary goal of this study was to test the following hypothesis: an intraoperative injection of autologous microfragmented adipose tissue processed with an enzyme-free technology could improve the clinical outcomes of single-row arthroscopic rotator cuff repair in terms of points in the Constant-Murley score (CMS) collected at least 5 years after surgery. Background and Significance: Rotator cuff surgery was initially proposed at the end of the 19th century and evolved then from open to arthroscopic techniques, rising quickly from a minor niche to a fully recognized subspecialty. To improve clinical and functional results and reduce the retear rate, new fixation techniques and biological solutions to enhance tendon healing are being developed at a fast pace, as shown by the dramatic increase in the number of articles published per year. Biological solutions to enhance rotator cuff healing include growth factors and platelet-rich plasma, as well as mesenchymal stem cells (MSCs) and their derivatives. MSCs are believed to enhance tissue healing mainly through stimulation of local cells via paracrine mechanisms and anti-inflammatory and/or immunomodulatory activity, thus creating a suitable microenvironment for tissue repair. Autologous microfragment…
