My knees are starting to give out at 55 due to (as my DO and PT put it), "high mileage" (running on a Precor Elliptical daily for 25+ years, mountain biking, roller blading, etc). Recent MRI has shown that cartilage damage has gotten worse since the 2016 MRI, and that I now have a "loose body" (floating cartilage or bone chip) in the left knee after spending 3+ months in PT for the right knee...UGH!
I'm super active - exercise every single day for 45+ minutes, and not being able to perform at the level I'm used to has really hit me hard..exercise is my "stress relief", and not being able to do it to the level I'm accustomed to is HARD (mentally).
Walking even 3 miles is painful, especially downhill. (Walking...SERIOUSLY?!!) Mountain biking for an hour..painful. Both are "doable", but it is tweaking me off beyond words that I can't just go do those things anymore at the ripe old age of 55..even DRIVING for 30+ minutes, for God's sake, is painful..
Not going to think about TKR..DO didn't push me for surgical intervention - YET..but am definitely concerned..
I'm used to just "sucking it up" and pushing forward on just about anything and everything. This scenario where your body basically says "um, nope!!"..is disconcerting..
