    Hi all,

    I often see osteoarthritis of knees internal side on genu valgum

    I seek a clear and precise explanation on the biomechanical phenomenon which explains this pathology

    I will like to understand the share of pinching, rotation, functional overload which generate this attrition

    thank you by advance

    To put it simply:

    Genu varum = increased risk of medial compartment OA
    Genu valgum = increased risk of lateral compartemnt OA

    Think of the direction of the centre of mass in the coronal plane being shifted towards each respective knee compartment, as the knee moves away from being in rectus. In a "neutral" knee, body weight is generally well distributed equally between each compartment.

    Make sense?

    Hi all,

    thanks for yours answers :)

    if I translates medial by intern and lateral by external, it is indeed a case of figure which I understands, that I know and that I can treat. :cool:

    but, I rest my question, I have evil has to find a good explanation biomechanical when I see a person with a genu valgum and a medial compartment OA :confused: :confused:

    wear is posterior and I will like to understand the share of rotation and especially at which time of the cycle of walk this OA occurs :eek:
