Posterolateral corner (PLC) knee injuries are often dubbed the "dark side of the force" due to their complex anatomy and challenging clinical evaluation. Frequently associated with acute ligament lesions, missing a PLC injury dramatically increases the risk of ACL reconstruction failure and accelerates degenerative joint issues.
In this video, Etienne Cavaignac details the essential primary stabilizers (the LCL, popliteus tendon, and popliteofibular ligament) and outlines precise diagnostic tests like the Dial and Houston tests.
Watch the full video to discover the essential clinical examinations, imaging strategies, and therapeutic indications to master these serious injuries.
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.
