About the department

The department of orthopaedics, trauma surgery and sports medicine at Johanna Etienne Hospital Neuss specialize in diagnosing and treating patients with musculoskeletal system diseases, wounds, and injuries. With 20 years of experience in arthroscopic operations, the department has been certified as a training centre for orthopaedic and trauma surgeons from all over Europe. The department works around the clock for urgent and emergency injuries. More than 2,700 successful surgeries are performed at the department every year. Since 2015, based on the department, endoprosthetics of the hip, knee and shoulder joints have been carried out. Doctors have the latest equipment for 3D diagnostics, which allows them to cooperate with manufacturers of prostheses and simulate the operation in advance. The department was also the first European centre to introduce a rapid recovery program for patients with an artificial shoulder joint.

The key focus is to provide the patient with the best possible care to maintain mobility. To do this, doctors rely on state-of-the-art, innovative surgical procedures combined with proven surgical techniques. For patients with uncontrolled chronic pain, the department has introduced the concept of multimodal inpatient pain therapy. During the nine-day stay, the patient undergoes an individually tailored diagnosis to identify the cause of the pain and eliminate it. In addition, modern physiotherapy and rehabilitation and health complexes will allow patients to return to everyday life much faster.
