1. Biodegradability: PLA degrades into lactic acid, which can be naturally metabolized by the body, eliminating the need for surgical removal of the scaffold. 2. Biocompatibility: PLA is generally well-tolerated by the body and does not cause significant immune reactions. 3. Versatility: PLA can be easily modified and combined with other materials to enhance its properties, such as mechanical strength and degradation rate. 4. Ease of fabrication: PLA can be processed using various techniques, allowing for the creation of complex and customized scaffold structures.
