Conventional or alternative medicine? Both are best. The point is to find out from all the possibilities the one that works and helps. Or even the right combination of both. Prim. Dr. Riedl is a specialist in orthopedics and orthopedic surgery, head of CORPUS and consultant orthopedist at the Rudolfinerhaus. The focus of patient-oriented orthopedic care is the combination of conventional medical therapies and operations with alternative medical options. In the degenerative joint area, his focus is also on cartilage-building joint-preserving measures in order to avoid joint replacement surgery as long as possible.
