Together with Philipp Lobenhoffer, Ronal J. van Heerwarden and Roland P. Jakob, Alex E. Staubli has written the reference manual on the state of the art of osteotomy techniques published for AO by Thieme Medical Publishers in 2009:
Osteotomies Around The Knee: Indications—Planning—Surgical Techniques Using Plate Fixators
Written by leading surgeons with expertise in performing osteotomies around the knee, this book is an essential reference for the current techniques in joint-preserving knee surgery. The book opens with a thorough discussion of physiology, pathophysiology, clinical evaluation, and imaging. It then describes the indications and basic principles of treatment and provides a detailed planning algorithm for high-tibial osteotomy. Separate chapters cover various clinical applications, addressing important topics ranging from the effects of osteotomies on cartilage pressure in the knee to management for failed osteotomies around knee. The book also discusses the latest technological developments in the field, such as computer-assisted navigation and the development of plate fixators.
Features
- Clinical insights and practical tips from experts in the field
- Detailed presentation of surgical techniques
- Numerous high-quality images and illustrations demonstrating key concepts
- Discussion of how to manage complications after high-tibial opening-wedge osteotomy

Osteotomies of the knee joint in patients with unicompartmental osteoarthritis

Abstract:
The basic principles of biomechanics, patient selection, proper planning, safe intraoperative technique with stable osteosynthesis, and early functional rehabilitation are the key factors for successful osteotomies around the knee. An individual unloading of the involved compartment should be the goal of this procedure.
Several different osteotomy techniques have been described in the past. On the tibia, the modern opening-wedge osteotomies offer significant advantages compared with the classical closing-wedge osteotomies. At the femur, closing-wedge medial and lateral osteotomies for varus and valgus malalignment are still the standard. Except for a few studies with selected patients, the long-term results of osteotomies around the knee are worse compared with the outcomes of unicondylar joint replacements. With the use of new biomechanical concepts together with modern osteosynthesis, osteotomy results can improve significantly.
Therefore, osteotomies around the knee remain the gold standard for middle-aged and active elderly patients with unicompartmental osteoarthritis of the knee.
Evolution of open-wedge high-tibial osteotomy: experience with a special angular stable device for internal fixation without interposition material
Editors: A.E. Staubli, H.A.C. Jakob
Abstract:
Surgical correction of bowed legs should be performed as early as possible. Overload osteoarthritis, even without significant varus deformity of the knee, is a further indication for open-wedge high-tibial osteotomy. Progression of damage to the joint surfaces due to overloading can be significantly retarded by realigning the extremity with the aim to, at least, reduce overload on the medial compartment to a value close to physiological.
We believe that open-wedge high-tibial osteotomy using Tomofix plate has proved to be successful in treating unicompartmental gonarthrosis, even without bone grafts or bone-substitute material.
