Grade: 3
Impact to inside of right knee, bashed it on a hold at the climbing wall. Didn't notice it at the time but tried a long run the next day - after 20 mins pain free I started to notice some discomfort, which gradually increased throughout the run. It seized up badly after and not it is sore to bend my knee at all.
I kept a light running load (15-25 mins per day) and resorted to biking and cross trainer for about a month. With more real rest it might well have recovered faster? Stayed worst of all in terrain - I guess it was a stability issue in the end.
