Untersuchung einer neuen Entnahmetechnik zur Optimierung der Mosaikplastik bei der Behandlung von Knorpeldefekten

In mosaicplasty, a proven method for treating small to medium-sized cartilage defects, osteochondral plugs are removed from a low-load region of the knee joint using a punch, which can damage the cartilage surface due to the resulting pressure. In order to avoid these disadvantages, a new type of removal device is to be developed that removes the plugs without damaging the cartilage surface, which could reduce the coefficient of friction and wear after implantation. Both established and newly developed methods will be used to validate this new technique in order to enable a meaningful comparison with the previous remov
