Does the new one click, creak, or otherwise bother you?
I’m been putting this off forever.
My left knee gave me so much pain, and was in such sad shape (an old football injury *snort*) that when I finally damaged it for the last time, I said, “I give! Uncle!”
I took a header over the handlebars of my bike, trying to brake for Igor, who had cut in front of me to make a right turn, knowing that I was behind him. When the doctor found arterial blood, he scheduled me for surgery two days later. (This was on a Saturday.)
The surgery itself was a breeze. But my body is strange, and instead of my knee having to be drained, it drained itself. I had to change the dressing every day for nearly a week.
However, if your knee is bad enough to put you on crutches, I would strongly recommend that you have an arthroscopy ASAP. You will not realize how bad the knee is until you no longer have to deal with the pain.
PS: My left knee is quite benign, compared to my right one, but I don’t want to be on crutches for a week, so I won’t have my right one done.
Get your knee fixed. It will thank you.
