Ronnie, I realize your post is quite old, but I was wondering how you're doing. I'm 6 months out from partial in both knees and my quadriceps are so weak despite working out constantly! Doctor said it will improve for up to 18 months so I am hopeful.
Thanks for your comment, I'll stick with it. It seems I'm working out more than a decathlete.
Hey Ron!
It may take a few months for the joint and muscles to gain strength and start functioning normally. Since everything appears to be fine, as judged by your surgeon; I would suggest continuing with physiotherapy for the time being. Hopefully things should improve in a few weeks.
Hope this helps.
Take care!
