Intraarticular administration of dexamethasone after mesenchymal stem cells implantation does not improve significantly the treatment of preestablished full-thickness chondral defect in a rabbit model

Espinosa, Maximiliano; Vaisman, Alex; Nazal, Nicolas; Figueroa, David; Gallegos, Marcela; Conget, Paulette (Sage Publications, 2013)

Objective: The aim of this study was to evaluate the contribution to hyaline cartilage regeneration of dexamethasone intraarticular administration after autologous mesenchymal stem cells (MSCs) implantation into a ...
Meniscus allograft transplantation: indications, techniques and outcomes

Figueroa, Francisco; Figueroa, David; Calvo, Rafael; Vaisman, Alex; Espregueira-Mendes, João (British Editorial Society of Bone & Joint Surgery, 2019)

New indications for meniscal allograft transplantation (MAT) are being added, but the general expert opinion is that it is still a procedure reserved for symptomatic meniscal loss. Lateral MAT has better clinical outcomes ...
Osteochondral autografts in full thickness patella cartilage lesions
