Abstract
Polymers have become essential in advancing bone tissue engineering, providing adaptable bone healing and regeneration solutions. Their biocompatibility and biodegradability make them ideal candidates for creating scaffolds that mimic the body’s natural extracellular matrix (ECM). However, significant challenges remain, including degradation by-products, insufficient mechanical strength, and suboptimal cellular interactions. This article addresses these challenges by evaluating the performance of polymers like poly(lactic-co-glycolic acid) (PLGA), polycaprolactone (PCL), and polylactic acid (PLA) in scaffold development. It also explores recent innovations, such as intelligent polymers, bioprinting, and the integration of bioactive molecules to enhance scaffold efficacy. We propose that overcoming current limitations requires a combination of novel biomaterials, advanced fabrication techniques, and tailored regulatory strategies. The future potential of polymer-based scaffolds in personalised regenerative medicine is discussed, focusing on their clinical applicability.
