I am 59 years old and have post-traumatic arthritis. A TKR is in my future. I have always been a cyclist and am wondering about any possible limitations on that activity post TKR. I live in a hilly area. Will standing up on the bike going up hill be contraindicated? How about just riding fast but staying in the seat? I REALLY love my bike.
