I have artificial knees. I had two total knee replacements in 2009.
My surgeon and physiotherapist both say that I am forbidden from doing heavy weight squats. I am limited to 85-ish lb. (It has to do with "stability" of artificial knees). I was doing hack squats in the 285-300lb range before surgery. (Well, before the arthritis left me able to barely walk). The leg press in the very basic gym I use only goes to 330lb. I figured I should be able to do a leg press in the range of 600+ lb (body weight plus BB weight). even allowing for being away from this I figured I should be able max the machine since I can do body weight squats by the dozen. (They have been my constant companion as a range of motion exercise since my surgery).
No such luck. I can do about 250.
Why is this? Should I be able to move my body weight in a leg press? Why the difference?
Thanks in advance.
