About a year ago I jogged 3-4 steps in a car park to get out of the way of a reversing vehicle. As my right foot landed the final step I got a very sharp pain on the inner front edge of the knee near the bottom of the kneecap. This caused me to limp for a while.
Since that time I have occaisional painful twinges, mainly when my foot isn't in the "straight ahead" position. Cycling isn't a problem
What have I injured, and what can I do to improve things?
