There is no possibility so far to make a completely used articular cartilage grow again, even though a certain «regeneration» of a damaged articular cartilage has been observed. Therefore, the artificial joint, i.e. the replacement of an articular cartilage by another material that glides well and permits good guidance in the joint, is often the best therapeutic option. The aim of the knee joint replacement is to restore the ability to bear weight, the mobility, and the stability, while reducing the pain.
The principle of the artificial joint has been known for decades and is now a standard treatment. Over 230'000 implanted knee joints per year in Europe substantiate the routine of this operation.
