Hurt knee

I hurt my knee yesterday while peddling. Been on this bike five years, was
not pushing a gear and had just turned out of the wind in the middle ring
about mid sprocket turning about a 66 cadence

The hurt is on the side at the bottom of my knee about 11 o-clock, it's
still tender today.



What I am wondering? The pedals had been turned in just a little all these
years (pigeon toed) and a week ago (four rides) I turned them straight.



Should the pedals be turned in just a little?



I ride again tomorrow on a closed course of two miles.



I'm a 66-year-old diabetic in very good shape, I lift three days a week and
cycle three days.

BP 110/65/51 sugar around 130 so I don't thing it's medical.



TIA for all comments.
