I'm assuming getting under a bar to squat is impossible then. Work around these limitations and you can build a good physique. Seems like you have the heart.
Welcome to UG
You sound motivated and willing to push past the injuries.
I blew out my patella three years ago in a car accident and have been recovering since. Been back at the gym hard for the last year and made solid gains... compression sleeves are your friend. No matter the body part in my opinion... I experienced much less discomfort and was able to recover more steadily while using a compression sleeve on my knee in the gym.
Welcome!
