New perspectives in the treatment of cartilage damage. Poly(ethylene glycol) diacrylate (PEGDA) scaffold. A review

This review was conducted as a complementary study to our review “Current concepts in the treatment of cartilage damage. A review”, in this same Journal, on promising new strategies in the treatment of cartilage defects. The established treatments such as osteochondral implants, bone marrow stimulation techniques and chondrogeneic cell implantations, besides advantages, have drawbacks that have led to seek new strategies such as scaffold materials. Matrix-associated chondrocyte implantation, hyaluronan-based scaffolds, tissue-engineered collagen matrices seeded with autologous chondrocytes and encapsulation of autologous chondrocytes in poly(ethylene glycol) diacrylate (PEGDA) seem to be less invasive and have a good performance. In this review we describe benefits and disadvantages of the new procedures of cartilage regeneration by scaffolding materials such as PEGDA.
