In this video, Prof Etienne Cavaignac and team describe their surgical technique for primary knee arthroplasties. It is a technique based on the principles of “adjusted inversed kinematic alignment” where both mechanical alignment and ligament tension are considered.
I am an orthopedic surgeon specialized in knee surgery. I practice at the University Hospital of Toulouse in the University Sports Clinic located in the Pierre Paul Riquet Hospital.
In addition to teaching at the Faculty of Medicine, I participate in courses for the professional societies to which I belong such as the SFA, ESSKA and SOFCOT.
My clinical activity (more than 800 surgeries per year) is exclusively focused on knee surgery. An important part of my surgeries is related to sports traumatology, in particular anterior cruciate ligament injuries (350+ ACL reconstructions per year).
My research activity is also focused on the knee. I have contributed to more than 110 publications in international journals. I am developing an à la carte approach in order to propose a personalized surgery to the patient. In the context of degenerative activity, the aim is to better analyze the variability of the anatomy in order to be able to propose prostheses adapted to the patient's anatomy. In the context of sports traumatology, it is a question of improving the dismemberment of all the lesions in order to propose an adequate therapy.
Since May 2022, I am a member of the board of ESSKA (European Society of Sports Traumatology Knee Surgery and Arthroscopy) as treasurer.
The particularity lies in the use of a 5-in-1 guide for the femur. Femoral rotation is determined after making an orthogonal tibial cut and using a tensor. Only uncemented implants are used except for the patella. This is a simple and efficient technique with a customization of the femoral rotation which they use in all cases of primary knee arthroplasty.
