Scientists from the Faculty of Medicine Carl Gustav Carus at the Dresden University of Technology have found a new approach to how to treat cartilage defects in the knee. The team uses a specially developed carrier material, a scaffold. The major challenge in the design was to find the best possible compromise between porous structure and strength, since the larger the spaces are designed for body cells, the more unstable the biomaterial scaffold becomes. But this is exactly the case if an implant is to withstand the natural movements of the joint in the future. In a collaboration between TU Dresden’s textile technology and the Center for Translational Bone, Joint and soft tissue research at the Medical Faculty, the textile technology of electrostatic flocking has been used world-wide for the production of biomaterial scaffolds with adjustable porosity and excellent mechanical strengths.
