Minimally-invasive operation techniques have established themselves increasingly in recent years. The background to this is the realisation that a smaller incisions and less damaging of soft tissue also cause fewer postoperative complications and lead to more rapid healing. These advantages have led to this new technology replacing many conventional operating techniques. Regenerative techniques in bioprosthetics can also be realised. These include the use of arthroscopic pins for regenerating defective cartilage zones. In the context of bioplanting, the arthroscopic pins utilised stimulate the growth of chondroblasts in the defective area, and these in turn stimulate the formation of fibrous cartilage tissue. Cartilage mass that can otherwise only be replaced with great difficulty by suitable implants can therefore be regenerated.

Arthroscopic pins of this nature can be manufactured with carbon fibre reinforced polymers (CFRP) which are characterised by excellent biocompatibility and can be produced to a high degree of purity. In addition, mechanical characteristics can be adapted across a broad spectrum to suit the application, from low rigidity to rigid, flexible to stiff.
