Evaluation of a Single Intra-Articular Injection of Autologous Adipose Tissue for the Treatment of Osteoarthritis: A Prospective Clinical Study in Dogs.

Objective:  The aim of this study was to investigate the safety, feasibility and clinical efficacy of a single intra-articular injection of autologous and purified micro-fragmented adipose tissue for the treatment of osteoarthritis (OA) in dogs.

Study Design:  Twenty-one client-owned dogs with radiographically confirmed OA were recruited into this prospective study. Lameness and discomfort were evaluated by physical examination at day 0 and then 14, 30, 60 and 180 days after injection.

Comparing "intra operative" tissue engineering strategies for the repair of craniofacial bone defects.

Background: In craniofacial reconstruction, the gold standard procedure for bone regeneration is the autologous bone graft (BG). However, this procedure requiring bone harvesting is a source of morbidity. Bone substitutes, such as biphasic calcium phosphate (BCP), represent an interesting alternative but are not sufficient for bone healing in hypoplastic conditions.

Autologous fat grafting: A comparative study of four current commercial protocols.

Background: Autologous fat grafting is a widely used technique that gives natural results when treating soft tissue deficiencies. However, there is no consensus on which is the best procedure to use, leading to unpredictable results because of fat graft resorption.

Objectives: This study compared four commercial lipotransfer devices by analyzing the behavior of the processed adipose tissue and outcome of the adipose graft in an in vivo model.

Olive and grape seed extract prevents post-traumatic osteoarthritis damages and exhibits in vitro anti IL-1β activities before and after oral consumption.

Polyphenols exert a large range of beneficial effects in the prevention of age-related diseases. We sought to determine whether an extract of olive and grape seed standardized according to hydroxytyrosol (HT) and procyanidins (PCy) content, exerts preventive anti-osteoathritic effects. To this aim, we evaluated whether the HT/PCy mix could (i) have in vitro anti-inflammatory and chondroprotective actions, (ii) exert anti-osteoarthritis effects in two post-traumatic animal models and (iii) retain its bioactivity after oral administration.

Effect of Washes and Centrifugation on the Efficacy of Lipofilling With or Without Local Anesthetic.

Background: Among the different parameters that influence fat graft survival and lipofilling success, the use of local anesthetic and the way to process the fat before injection have often been pointed out. Likewise, we evaluated different techniques for processing adipose tissue before its injection and analyzed the quality of the grafts.

Methods: Adipose tissue from the same patient was gently harvested from one side of the abdomen after infiltration of a tumescent solution without lidocaine and from the other side of the abdomen using a tumescent solution containing lidocaine 2%.
