Hi, I've always had knees that clicked out of place every so often and if I sit down and move my lower leg I can feel popping in my knee. As it's not usually painful, I've ignored this. Another reason I've ignored it is that friends who have had knee surgery have been placed on lifetime bans from squatting and running. Does anyone know if this is usual or exceptional? Personally, I'd rather have knees that I can lift with that click, rather than knees that don't click but are functionally limited. Anyone have/had a similar problem?
