I've not been around the forum much with the hols and the worst case of gastro I could ever imagine. Definitely in the TMI category, I'll move on.
New physio project is the VMO - Vastus Medialis Oblique -basically the bottom of the quads on the medial (inner) side. Mine 'fires' late and it's the bit that will get me the terminal range of motion to straighten my leg.
I'm doing three exercises at the moment, first is to sit in a chair with ~90 degree bend foot flat on the floor with weight on the heel. As I push down I have to concentrate on the VMO activating before the lateral stabilizing muscles kick in. Next I do a one legged partial squat which isolates it nicely and finally a parial forward lunge with hands on hip bending at the waist - with the bend it really works the VMO. We've now discovered weak glutes on this leg. On a -5 to 5 scale I have 4 on my good right leg and -4 on the new left knee side.
It's amazing to realize how the body does its best to compensate for an injury. I SO should have had the TKR done when I was 30, not 50 but it just wasn't something surgeons would contemplate for me back in '80's-'90's. So glad medical science has moved forward so others don't wind up suffering this (in my opinion) worse damage from waiting.
