I've "runners knee" that has recently improved so much that I've been able to do some short sprinting, and it's felt better than it has in years. Then Saturday I had a little fall on the trail (rear tire slipped in some deep dust) and bumped my knee pretty well - aggravating this condition

Things are feeling much better, but I want to give my knee some additional support between now and my vacation. While the pain is mostly gone, I can tell that there is still some inflammation in the knee when I walk down steps. I like the look of something like this and don't think I need something like this.

Has anyone successfully used the more simple knee strap for patella problems? It isn't as bad as the last time I aggravated it, just trying to support it while continuing my activities at a lower intensity level - and I've scheduled more rest days this week than normal which will also help.
