Recently, it has been proven that cartilage healing is difficult. The most commonly used treatments are autogenously cartilage grafting and allogeneic bone grafting, but grafts cannot fully meet treatment goals because of source, price, safety, and other concerns. Thus, a combination of biological materials and tissue engineering technology has become a recent trend in studies. Among the studies performed on tissue engineering cartilage materials are hydrogels that exhibit biological activity, post-decomposition adsorption, flexibility, and easy preparation. Cell-containing hydrogels are often used in cartilage tissue engineering because of their biocompatibility, ease of use, and ability to adapt to different defects. Hydrogels are used to mimic extracellular matrices. Although multiple materials can configure and form hydrogels, hyaluronic acid and its derivatives are distinguished. Hyaluronic acid (HA) is an extracellular molecule with several physical and biological functions found in many tissues, including cartilage. HA is formed in several biomaterial systems and scaffolding. HA hydrogels have many interests, including increased adhesion, cell proliferation, and wound healing. In addition, they represent adequate biological acting for stimulating a microenvironment for the survival of cells. However, their disadvantages include a slow degradation rate and low mechanical properties. Here, HA-based hydrogels and their applications in cartilage tissue engineering are briefly reviewed.
