After two major knee manglements here is my list.
1. Keep them warm!!!
2. Lots of slop (aka float) in my pedals.
3. No walking long distances on hard surfaces. Oddly, running is ok.
4. No standing on the pedals with gear. Spin up dem hills.
5. Train at higher rpms. (I tour at a lower wattage and lower cadence.)
6. For me Naproxin >>>>> ibuprofin.
