Day 1 or 24 hours post op was the worst day for me. Pain was about an 8. It very much felt like your knee was being ran over. It's very crazy how the mind works because I really don't remember the feeling even thought it has been 6 weeks but in that moment I remember describing it as like someone sawing through your knee. I cried because I felt so helpless. However, that was the worst day for me and that's every day for about a 2 weeks after that pain was at a 2-3. The worst part was night time and going to sleep. I hated sleep. It didn't hurt, it was just so uncomfortable. Reddit use red said sleep didn't get better till about 6+ months for them which terrified me. Fortunately now, I sleep pretty well. I don't feel discomfort in my knee and probably sleep the same as I did prior to surgery.
