Orthopedic Specialist for Knee and Hip Disorders
ONZ is internationally renowned for preserving joint function in knee and hip treatments through innovative and minimally invasive surgical solutions.
Welcome to ONZ's hip and knee center.
Expertise without borders.
Assoc. Prof. Dr. Wolfram Steens
co-founder of ONZ and the Cureon Clinic, serves as the medical head of the hip and knee department. He has made it his mission to provide patients from around the world with access to high-quality orthopedic care – following German medical standards.
With a strong focus on knee and hip treatments and a trusted international network, Dr. Steens and his team regularly welcome patients who are seeking reliable diagnostics, expert surgical care, and a streamlined treatment process in Germany.
One major challenge he has long recognized: excessive waiting times for joint surgery – especially abroad – often resulting in prolonged pain and extended periods off work. His solution: the establishment of the Cureon Clinic, a large, state-of-the-art surgical center that operates independently of public hospitals.
This independence enables highly efficient planning, short waiting times, and a comfortable treatment environment – without compromising on medical precision or safety.
Driven by experience, precision, and a clear international outlook, Dr. Steens is committed to ensuring that patients receive the care they need – when they need it.

Daniel “Dan” Pohl
With a background in sports, rehabilitation and over 25 years of experience supporting people with orthopedic and neurological conditions, Dan Pohl understands the difference the right care can make. After working with thousands of injured clients in Canada, he experienced the limits of public healthcare firsthand — when his own mother needed a hip replacement.
From personal experience to expert guidance
In search of true quality care, Dan turned to Dr. Steens and the ONZ team in Germany. Within four weeks, his 74-year-old mother received surgery and began a structured, intensive rehabilitation program — walking pain-free just three weeks later.
Today, Dan supports international patients in making the same journey: informed, efficient, and built on trust. With both professional and personal insight, he is your dedicated contact at ONZ.
