Following a similiar thread, it occurred to me I still have a dodgy knee, quite annoying when its bad. Not necessarily painful, but enough to can a walk when its really bad. Has anyone had success with the sport/or other style knee supports available? The ligaments etc make a bit of a "clunk" on the outside/ lower 3/4 area of the patella. It started after an impact injury in that location, but doesn't seem to have gotten worse over time, touch wood. Anyone?
