I've never discussed this, but I am a disabled veteran. I was discharged from the Marine Corps in 1995 with a medical discharge. I got busted up a little bit & destroyed the lower part of my knee cap. I had a few surgeries & they amputated the lower part of the patella & stretched the ACL & reattached it. That in itself has been a problem that I have to overcome from time to time. I had to wear a cast from my hip to my toes for a year so that everything had time to heal sufficiently (Especially the ACL). When they took my cast off my left was significantly smaller than my right & especially my quad. This has been a battle for many years now for different reasons, but It was over an inch different in the beginning. I have now got them within a 1/4". My question is this. What type of leg workout would be the most beneficial to getting both legs the same size. If I was wearing shorts, which I never do, you can easily see the difference in diameter. Do I maintain the right leg while working the left harder? Y'all put your minds together & help out an old disabled Devil Dog!!!
