Does 'mild extrusion of the medial meniscus" (u/s report) benefit from surgery? i'm 72, female and an active walker.

Meniscus: As the body ages, degenerative (or age-related) changes of the meniscus are common, including tears and varying degrees of "extrusion" (or bulging out). It is unlikely that surgery would be of significant long term benefit, unless you have frequent locking or catching of the knee along the medial (inside) area. Recommend continuing your active walking and consulting with an orthopedic surgeon
