In July 2017 I had an ACL repair along with partial meniscectomy. My recovery went well with regular doctor check ups and physical therapy. Over the last 7 months I've had something occur a few times and I'm wondering if anyone else has had something similar. I workout 4 times a week, I'm careful and have not had any workout related pain afterwards. But randomly I'll have moments where my knee just swells up and feels like I've somehow hurt it. It'll happen randomly, once it was when I went to sit down, most recently it was after walking down a hill. It almost seems like I've "stepped wrong" and it puts me out of commission for about a week while the swelling comes down and my knee feels normal again. During that week my knee will feel weak and daily things like stair climbing, will be a little difficult. I'm wondering if this is something that I'll have to deal with for the rest of my life or am I still technically in a recovery phase that can take years. Has anyone else dealt with something like this?
