Abstract
This article describes the process of developing a tissue-engineered structure that meets the biocompatibility and biodegradation parameters necessary for replacing cartilage tissue defects. The study was carried out using 3D bioprinting technology, which represents a promising research direction in the biomedical field. It is known that, due to the specifics of its structure, cartilage tissue is not capable of complete regeneration of damage. The methods currently used for treating arthrosis are associated with a number of limitations and disadvantages, which makes research aimed at developing alternative methods for arthrosis treatment particularly relevant. The development of tissue-engineered structures by 3D bioprinting requires the materials not only certified for medical use but also exhibiting biocompatibility and biodegradation properties. Polylactide (PLA) and sodium alginate satisfy the above requirements; moreover, their availability and economic affordability make them one of the most popular materials for 3D bioprinting.
