I'm a 56 year old male and I've had numerous knee surgeries over the years - bilateral ACL reconstructions as well as multiple meniscectomies As a result, I have nothing like the full complement of meniscus/cartilage in either knee and now have OA in both. It ranges from mild to moderate to severe in different parts of the knee (I'm bone on bone in places).
My question is: when is it time to stop running?
I realize I'm an excellent candidate for knee replacements in the future - that's a given - but I want to remain active (i.e running) as long as I can.
I've asked my knee surgeon but she is vague: "You can run until it hurts too much". But what is too much?
Today, I really don't have that much discomfort when running. Afterward, I get some aching but nothing a couple of Advil doesn't fix. Same with biking.
Does that constitute "too much"?
I'm also careful to run primarily on forgiving surfaces - treadmills, track, trails. I avoid asphalt and concrete.
Would really like to hear your experiences/thoughts/advice - thanks!
