question: I had an ACL and meniscus repair with grafting on my left knee a year ago. A day ago I started feeling like there was a squishy not grinding or cracking but a squishy feeling inside my knee and there is lots of swelling? It is to the point where I’m having trouble bending and walking but very little pain. I’m not sure why as there was no trauma or unusual activity that I did that could cause injury to the knee.
