You're correct and I absolutely agree that every knee injury is different and it's why I preface this thread with, "
I think....".
I think, in general my active lifestyle makes my knees stronger, except when I do stupid things, like over do it, which I have a tendency to do. I do believe the most important thing for good knee health, besides diet is working all the muscles and connective tissues around the knee. We cyclists (and runners) tend to have much stronger quads as compared to our hamstrings and posterior chain in general. That's why I do weightlifting, to get everything. I do believe weightlifting is so very important for us old dudes -- won't be too long before I hit the big Six-O.
I did my run yesterday and if felt better than the other day, but still have this funny stiffness, but it's also getting better. Getting ready to do a long bike ride -- will try very hard to take it easy
