Hello, I'm new on this forum and I need your help.

Last sunday, after a break of 3 weeks without cycling, I did 45 min on my home trainer and a knee pain immediatly appear after. The result: my doctor diagnostic me a tendinistis on the muscle behing my knee.

Here my background: around 10 years ago, I had a major surgery on my femur. At this moment, my right leg was 3'' shorter than the left one so the surgery consist on increasing my right femur lenght.

SO to summarize it: now, my both legs are equal BUT my right femur is around 2'' longer.

Or course, my bike positionning is done based on my left leg and that's why I'm having problem with my right knee.

Is there somebody with a similar problem (lenght discrepency) and what do you do to prevent injury (modification to your bike, exercice, see doctor etc).

Thank you very much for your help. I know my situation is complicated but I'm sure there is something to do.
