Dr Kristian Kley is a consultant orthopaedic surgeon with a specialist focus on hip and knee conditions. His passion for improving orthopaedic care was sparked during his medical training following a personal ligament injury, which led him to pursue a career in trauma and joint surgery.
While his early colleagues concentrated on knee procedures, Dr Kley turned his attention to the hip—refining his skills under the guidance of leading surgeons at Orthopädische Chirurgie München (OCM). Inspired by the Rottinger Approach to hip replacement, he began developing innovative surgical techniques that prioritise both precision and patient recovery.
His work led to the evolution of a streamlined, minimally invasive method now known as the Kley Rapid Hip procedure. This advanced technique—rooted in a surgical approach first introduced in the UK by Mr Watson-Jones in the 1930s and later modified by Professor Rottinger—has been further refined by Dr Kley over the past 15 years. Today, it stands as one of the world’s safest and most effective hip replacement procedures.
At Orthopaedic Innovation, our international surgical team brings deep expertise in this approach, helping patients return to movement faster, with less discomfort and reduced downtime.
The Kley Rapid Hip method for hip replacements is based on the Rottinger approach - a well-established, minimally invasive technique for total hip replacements that has been successfully used worldwide. Dr Kristian Kley has further enhanced and performed this procedure on over 3,000 patients. Through numerous research studies, this technique and has been shown to be safe and effective with some studies showing reduced complications and better function than other surgical hip replacement methods.
The Kley Rapid Hip method is minimally invasive, muscle-sparing, and designed as a day-case procedure that’s appropriate for a wide range of patients. Here’s why we think it’s the best choice:
If you’ve been living with chronic hip pain due to arthritis, injury, or degeneration, hip joint replacement might be the next step. The Kley Rapid Hip approach is especially beneficial for individuals who are motivated to return to their normal routines quickly and are in good general health. But it has been developed to be appropriate for a wide range of patients, and results in less trauma and better outcomes for patients.
Our modern approach to hip surgery combines cutting-edge surgical methods, such as minimally invasive and muscle-sparing techniques, with tailored rehabilitation protocols to help patients recover faster and more comfortably than ever before.
