Special Clinical Focus

  • Joint-conserving hip surgery (incl. complex pelvic and femoral osteotomies, surgical hip dislocation, hip arthroscopy)
  • Full range of pelvic traumatology, including acetabular fractures and complex hip fractures
  • Hip replacement incl. minimally invasive approaches and complex reconstructions
  • Revision surgery of the hip
  • Tumor surgery of the musculoskeletal system

About us

The Department of Orthopedic Surgery focuses on the prevention, diagnosis and treatment of diseases and injuries of the musculoskeletal system. The department offers specialty consultation hours for the hip/pelvis, spine, shoulder and elbow, knee as well as the ankle/foot.

Each of these teams conducts weekly consultation hours for outpatients. The surgical spectrum includes arthroscopy, prosthetic replacement, tumor surgery, osteosynthesis, computer-assisted surgery, soft tissue reconstruction, osteotomy and ligament reconstruction. As a result of continuous research, new treatment methods are being developed on an ongoing basis.

Introduction of team members:

Prof. Klaus A. Siebenrock, Clinic Director and Chief Physician, Team Leader Hip and Pelvis
As Chief Physician, Prof. Siebenrock also heads the hip and pelvis team. His expertise is particularly valued in complex surgeries, whether it is a matter of preserving joints - or whether it is about artificial joints. He also has extensive experience in sports traumatology and revision surgery of hip prostheses. Thanks to his international network and his membership in several top-class professional societies, he always stays up to date.

Associate Lecturer Dr. Dr. Frank Klenke, Team Leader Knee, Head of the Sarcoma Center
Associate Lecturer Dr. Dr. Klenke, head of the nationally known Sarcoma Center and Team Leader Knee, has made a name for himself as a proven specialist in tumor orthopedics from precise diagnostics to sensitive aftercare. As a knee expert, he is just as adept at joint preservation as he is at prostheses. He also has an enormous reputation in research, for example with papers on bone healing. This is not the only reason why he is a welcome guest at symposia.

Prof. Fabian G. Krause, Team Leader Foot and Ankle
As Team Leader Foot and Ankle, Prof. Krause is familiar with all diseases and deformities of the foot, especially with hollow and flat feet and with osteoarthritis. His expertise is also in demand for questions regarding cartilage damage or ankle instability. Whether hammer toes or claw toes, hallux valgus or problems with the Achilles tendon - the specialist, who also belongs to many renowned professional societies, has a lot of experience.

Dr. Michael Schär, Team Leader Shoulder, Elbow and Sports Medicine
Dr. Schär, Team Leader Shoulder, Elbow and Sports Medicine, has specialised above all in joint osteoarthritis and artificial joints. Especially when people with prostheses have to fight infections, he is considered the ideal person to consult. He has also gained an excellent reputation in sports circles - for example for tears in the rotator cuff or tendon transfers in the event of defects. He also has impressive expertise in tumor surgery.

Associate Lecturer Dr. Johannes D. Bastian, Head of Orthogeriatrics, Hip and Pelvis Team
Associate Lecturer Dr. Bastian is also part of the hip and pelvis team as Head of Orthogeriatrics. This makes him exactly the right specialist when it comes to maintaining the mobility of elderly patients - in which his experience in prosthetics also comes in handy. Geriatric traumatology is also one of his absolute specialties. Also worth mentioning: in 2018 he received the coveted "SWIF AWARD" for his commitment to further medical education.

Prof. Lorin M. Benneker, Team Leader Spine
As Team Leader Spine, Prof. Benneker has an extremely high level of expertise in injuries and deformities in all areas of the spine and pelvis. He has also made a name for himself with tumors, from diagnostics to surgery and post-treatment, and is therefore also in great demand for second opinions. His scientific work focuses, among other things, on the regeneration of the intervertebral disc, from which his patients also benefit.
