Injectable hydrogels are effective for cartilage and bone tissue engineering due to their minimally invasive application, which allows for easy cell and bioactive molecule incorporation and better integration with surrounding tissues.
This chapter reviews recent developments in injectable hydrogels, exploring commonly used natural and synthetic materials and their fabrication techniques.
Achieving the ideal hydrogel design with the right gelation time and necessary properties (bioactive, biocompatible, biodegradable, and mechanically robust) for effective clinical use remains a key medical challenge.
