AutumnBreeze - if you have a hole in your knee, you might have a puncture wound, not just a cut. Its important to keep those draining, if you dont they can abcess and get very ugly. Also if you have ANY pain inside the joint itself, get thee butt to a doctor. I had a puncture wound in my right knee a few years ago that got into the joint and got infected, I was down for a month and it was hell.

Hope your back on your wheels soon.
