About Dr. Kristian Kley

Dr. Kristian Kley is a Consultant Orthopaedic Surgeon with many years of experience in orthopaedic hip and knee surgery.

Dr. Kley completed his medical degree at Hannover Medical School (MHH) in 2005, before training under Professor Philipp Lobenhoffer and going on to specialise in trauma and orthopaedic surgery, qualifying as an Orthopaedic & Trauma Surgeon and earning his doctorate.

He subsequently expanded into hip surgery, refining techniques inspired by the Rottinger Approach and developing his own rapid recovery hip replacement method. He has performed over 7,000 joint replacements in the last 15 years across Germany and the UK, including 550 hip and 350 knee replacements in the past 12 months.

Alongside his hip work, Dr. Kley also has a strong interest in knee osteotomy, using computer simulation for complex cases and kneecap stabilisation, and carries out around 300 knee osteotomies a year. He is a member of the Joint Preservation Expert Group of the AO Foundation and has authored 25 PubMed publications on knee osteotomy in the past three years.

He is a star. He diagnosed my faulty hip and the fact that it was causing problems with my knee (I had been limping for three years. Other specialists had missed the connection). The hip replacement was excellent. It was done quickly which meant a speedy recovery. Overall very satisfied.

I would reccomend to anyone who is suffering with constant hip pain and disability due to severe arthritis, make an appointment to see the team at orthopaedic innovation today! Kristian gave me bilateral hip replacements with minimal scaring and the procedure done in approx 25 minutes each hip. I have been given my indepenance back and I am pain free. Kristian is a very talented amazing surgeon.
