AmputeeOT: How An Above Knee (AK) Prosthetic Leg Works
I am 56 and 6 weeks post-op bilateral knee replacement. My doctor and my physical therapist both told me I should not kneel due to the ‘button’ on the inside of the replaced knee caps. They are prone to becoming wedged and/ or bent if forced against the joint prosthesis, which would necessitate another surgery to undo the damage.
I have tried to garden and have found the easiest position is seated on a low stool (higher than a footstool). To rise I can use the legs of the stool or the seat itself for leverage and support. It’s not the best solution but it works for now.

Total knee replacement is actually a resurfacing procedure where approximately ½ inch of bone is removed from the lower end of the thigh bone (femur), the upper end of the lower leg bone (tibia), and the under-surface of the knee cap (patella). These surfaces are then covered with a metal prosthesis on the femur and a plastic prosthesis on the tibia and patella.
