Joint diseases, such as knee osteoarthritis, are common in the elderly population and severely impair their quality of life. Conventional treatments like artificial joint replacements offer temporary relief but come with several disadvantages, including limited functionality and the need for replacement. A better solution is to find a way to promote tissue regeneration in joints: interpenetrating polymer network (IPN) hydrogels, when injected into joints, do exactly this—by acting as scaffolds for the growth of new cells and mimicking the cellular environment. However, existing techniques to develop IPNs are tedious: they require the addition of chemicals via multiple steps, which limits their practical application. Thus, there is a need for better techniques that can make the process of tissue regeneration easier.
