REGENERATION OF ARTICULAR CARTILAGE: SCAFFOLD USED IN ORTHOPEDIC SURGERY. A SHORT HANDBOOK OF AVAILABLE PRODUCTS FOR REGENERATIVE JOINTS SURGERY

An equine enzymatically deantigenated collagen membrane to support cartilage repair

Restoring defects of load-bearing connective tissues such as articular cartilage resulting from traumas, degenerative or age-related diseases remains a significant clinical challenge for clinicians due to the limited inherent repair capacity of articular cartilage. Tissue engineering has emerged as a potential alternative to the traditional surgical techniques, as it can be effectively used to regenerate bone, cartilage and the bone-cartilage interface. Several scaffold strategies have been developed and evaluated for osteochondral defect repair. he classes of polymers (scaffold-based proteins, scaffold-base polysaccharides and synthetic scaffolds) and Hydrogels have been reviewed trough literature and market search. The study focused on their respective properties and analyzed advantages and disadvantages of each of them. Clinical studies demonstrated improved cartilage regeneration thanks to the implantation of biomaterials after bone marrow stimulation. New cartilage can be engineered in vivo by transplanting chondrocytes seeded into a three-dimensional scaffold and this novel scaffold has mechanical properties that can be comparable to native cartilage and could be used to repair large osteochondral joints defects. Anyway, there is still space for improvement regarding clinical outcome and tissue quality.
