INTRODUCTION Osteochondral articular defects are a key concern in orthopaedic surgery. Current surgical techniques to repair osteochondral defects lead to poor subchondral bone regeneration and fibrocartilage formation, which is often associated with joint pain and stiffness. The objective of this pilot clinical study is to evaluate the performance and the(More)
UNLABELLED The ideal treatment of osteochondral lesions is debatable. Although autologous chondrocyte implantation provides pain relief, the need for two operations and high costs has prompted a search for alternatives. Bone marrow-derived cells may represent the future in osteochondral repair. Using a device to concentrate bone marrow-derived cells and(More)
BACKGROUND Platelet-rich plasma (PRP) has been advocated as one treatment for cartilage tissue regeneration. To date, several different platelet-rich formulations have been available, but a deep knowledge of their composition and mechanism of action in a specific clinical use is needed. The aim of this study was to investigate the effect of various PRP(More)
The aim of this study was to assess the repair of osteochondral defects of the ankle joint with hyaline cartilage. For this purpose we have been using a technique of autologous chondrocyte transplantation for osteochondral defects of the talus for the last two years. Until the method described in the paper, treatment methods proposed for the repair of(More)
OBJECTIVE The purpose of our study was to determine the effectiveness of cartilage repair utilizing 1-step surgery with bone marrow aspirate concentrate (BMAC) and a collagen I/III matrix (Chondro-Gide, Geistlich, Wolhusen, Switzerland). MATERIALS AND METHODS We prospectively followed up for 2 years 15 patients (mean age, 48 years) who were operated for(More)
With the continuous discovery of new alternative sources containing mesenchymal stem cells (MSCs), regenerative medicine therapies may find tailored applications in the clinics. Although these cells have been demonstrated to express specific mesenchymal markers and are able to differentiate into mesenchymal lineages in ad hoc culture conditions, it is still(More)
BACKGROUND Autologous chondrocyte implantation (ACI) in the ankle was considered up to now an extremely technically demanding surgery with considerable morbidity for the patients. HYPOTHESIS Hyalograft C scaffold allows arthroscopic ACI, thanks to a specifically designed instrumentation. STUDY DESIGN Case series; Level of evidence, 4. METHODS(More)
OBJECTIVE Autologous chondrocyte implantation (ACI) has been successfully used for the treatment of osteochondral lesions of the talus. One of the main problems of this surgical strategy is related to the harvesting of the cartilage slice from a healthy knee. The aim of this study was to examine the capacity of chondrocytes harvested from a detached(More)
Association of biomaterials with autologous cells can provide a new generation of implantable devices for cartilage repair. Such scaffolds should provide a preformed three-dimensional shape and prevent cells from escaping into the articular cavity. Furthermore, these constructs should have sufficient mechanical strength to facilitate handling in a clinical(More)
