This technology is a bioactive, electrospun fibrous polymeric scaffold designed to enhance cartilage repair by promoting chondrocyte growth, matrix deposition, and graft integration in orthopedic and regenerative medicine applications.
Current treatments for cartilage damage, such as microfracture surgery or autologous chondrocyte implantation, often result in incomplete healing or the formation of biomechanically inferior fibrocartilage. These approaches lack the ability to fully restore native cartilage structure and function, leading to limited long-term durability and joint degeneration, primarily due to the zone of chondrocyte death, a dense region of necrosed cells lining the periphery of the wound edge in cartilage autografts and damaged host tissue. There is a critical need for solutions that better support cell viability, matrix production, and integration with surrounding tissue. Addressing these shortcomings is essential to improve patient outcomes and reduce the progression to osteoarthritis or the need for joint replacement.
The technology utilizes a fibrous polymeric scaffold designed to promote cartilage repair by creating an environment conducive to chondrocyte proliferation and extracellular matrix deposition. The scaffold incorporates electroactive properties through the inclusion of graphite particles, which mimic the electroactivity of native cartilage and aid in mechano-transduction, helping cells respond to mechanical stimuli. Additionally, the scaffold’s surface is optimized to attract cell adhesion proteins, improving cell attachment and enhancing integration with surrounding tissue. Its architecture also supports the growth of cartilage-like tissue, promoting better structural repair in areas of damage or degeneration. Prototyping and testing have shown that the scaffold can effectively encourage chondrocyte growth and collagen production, demonstrating its potential for use in cartilage grafts and tissue engineering applications.
