Modern joint surgery has witnessed medical successes, which just a few decades ago were hardly imaginable. Variations of endoprostheses, which have seen improvements in both form and service quality thanks to the Microfinish / Superfinish process, have also contributed to this success. This applies in particular to the technical optimisation of ball and socket joints.
The machining of these components leads to improvements in the micro-and macro-geometry, which are decisive for their longevity, as well as ensuring a high load-bearing capacity and a reduction in the specific surface load. The process also removes the amorphous layer, meaning that the healthy base material can be fully exploited in terms of hardness and durability. In practice, a further benefit can be seen in the increase of useful pressure characteristics in the outer layers.
