I just read the MRI report on my right knee. I find it hard to believe but nothing is torn. I do have some chondromalacia (deterioration of the cartilage under my left knee cap). I ride a bike but I have runner’s knee. Frankly, given my symptoms, I find this a bit hard to believe.
I did some research and found that one way to fix chronic knee pain is to use shorter crank arms on your bike. (This is pretty common in the recumbent world.) The reason is that you have less flex in your leg at the top of the pedal stroke when you push down. (This is exactly when my knee aches.)
All of my bikes use 175mm length cranks which come stock on bikes for people my height.
So I have a question.
Do you use cranks shorter than 175mm?
