ENDOPROTHETICUM Rhein-Main is an orthopaedic specialty practice for joint replacement and joint surgery in Mainz, centered on hip and knee endoprosthetics. The practice provides specialized diagnostics and planning, and supports treatment pathways that include minimally invasive surgery and structured after-treatment. In hip replacement, Prof. Dr. med. Karl Philipp Kutzner is particularly known for minimally invasive techniques and short-stem hip arthroplasty. A key area of expertise is calcar-guided short-stem prostheses, which aim to reconstruct hip biomechanics while using a bone- and soft tissue-sparing implantation technique. The concept is explained through a “kalkar-guided” approach—stabilization of the implant along the calcar structure to support more physiological load transfer. The practice also highlights minimally invasive anterolateral access (front-lateral), described as the “Wiesbaden approach,” designed to avoid injury to surrounding musculature. In knee arthroplasty, treatment includes knee prostheses and partial joint replacements when appropriate. ENDOPROTHETICUM positions itself as a concept of “all from a single source,” combining surgical expertise with integrated rehabilitation support. For patients considering short-stem options, the practice emphasizes modern planning and bone-preserving principles. International patients benefit from additional coordination support when being treated at partner facilities such as curaparc clinic in Mainz and LILIUM-CLINIC in Wiesbaden. The foreign-patient support includes English-speaking staff and—if needed—a dedicated contact person to help plan the stay. ENDOPROTHETICUM’s team consists of Prof. Dr. med. Karl Philipp Kutzner, Nerminа Murtic, and Juliane Hoidn, reinforcing the practice’s focused, specialty-driven model. The clinic also shares educational materials on short-stem total hip arthroplasty, describing benefits such as bone preservation, enhanced recovery, and reduced risk of thigh pain. The collaboration with partner inpatient facilities helps create a treatment chain from preoperative evaluation to operation and early rehabilitation. In addition, the practice has its own approach to aftercare, including an announced own rehabilitation facility starting in 2025 with direct oversight by the treating surgeon.
