Osteochondral (OC) defects, resulting from cartilage degeneration or traumatic injury, can lead to significant complications. Traditional treatment approaches often result in fibrocartilage formation instead of articular cartilage, or carry a risk of disease transmission, raising considerable concerns. In response, OC tissue engineering has emerged as a promising strategy for defect regeneration. Hydrogels, particularly stimuli-responsive types such as photocrosslinked hydrogels, play a crucial role in this approach. These hydrogels, which respond to external stimuli like light, offer precise control over their properties, making them highly suitable for OC repair. Photocrosslinked hydrogels have been extensively studied for their ability to support chondrocytes and promote cartilage matrix synthesis both in vitro and in vivo, thereby facilitating tissue regeneration. Photopolymerization methods, involving photoinitiators, are central to their synthesis, offering control over gelation speed and hydrogel properties. Despite the promising potential of these materials, challenges related to mechanical strength and long-term stability remain. This chapter provides an overview of the materials, properties, and applications of photocrosslinked hydrogels in OC repair, highlighting recent advancements and future perspectives aimed at enhancing their therapeutic efficacy in tissue engineering.
