Focus on arthrogenic muscle inhibition (AMI)

Arthrogenic muscle inhibition (AMI) is a phenomenon affecting recovery after knee trauma or surgery, particularly following an ACL rupture or reconstruction. AMI leads to muscle weakness, gait abnormalities, and an increased risk of early osteoarthritis. This presentation highlights the different grades of AMI, its pathophysiology, contributing and protective factors, as well as potential treatment options to address this condition.

Course Director

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.
