From the February issue: Effect of Slope and Varus Correction High Tibial Osteotomy in the ACL-Deficient and ACL-Reconstructed Knee on Kinematics and ACL Graft Force: A Biomechanical Analysis

Podcast: Listen to Dr. Imhoff discuss his article in the February issue.


Dr. Florian Imhoff is a young swiss-german orthopaedic surgeon specialized in knee surgery and sports medicine. He currently works at the prestigious Balgrist University Hospital in Zurich, Switzerland, as a consultant. He is member of several specialty societies such as the AGA and ESSKA, and the German Knee Society.

After his residency in trauma surgery and general orthopaedics starting in 2011, he was able to gain insights in ligament and cartilage injuries around the knee and bony corrections of knee deformities in the Department of Orthopaedic Sports Medicine
 at the Technical University of Munich, Germany in 2016. Thereafter, he completed a one year research fellowship in the translational and biomechanics lab at the Musculoskeletal Institute, University of Connecticut Health Center in Connecticut, USA (Professor Robert Arciero, Professor Augustus Mazzocca). By then, he developed a biomechanical testing model to evaluate the influence of bony malformities, corrective osteotomy and ligamentous insufficiencies. Moreover, during his time there he developed a 3D modeling system to predict torsional as well as angular correction of femoral torsion osteotomies in correcting deformities of the distal femur. He developed a 3D planning module for derotational osteotomies of the leg and a new patellofemoral measuring tool within a dicom planning application.

In 2019, he finished his post-doctoral habilitation at the Technical University of Munich, Germany, and received the professor’s teaching diploma (privat-dozent, PD) of the University. In the last years, he has presented many scientific studies focusing on ACL and peripheral knee structures. His overall publication legacy is extraordinary. Furthermore, he has received several awards among them the Caspari Award from ISAKOS or the Alwin Jäger Award from AGA. In addition, he serves as reviewer for “American Journal of Sports Medicine” and many others.

“This young surgeon is one of the brightest, creative, and practical physicians I have ever met in my 32 years of training residents and fellows. He is a “star”. He will spend his professional life devoted to improving clinical care and patient outcomes particularly as it pertains to knee ligament, ACL injury and complex acquired deformities and deficiencies of meniscus and articular cartilage.”  Prof. Robert Arciero, July 2019
