So I spent all day walking around with my new patellar straps on, and I have to say, damn that makes a hell of a difference.
Not only did my knees feel much more stable all day; especially while in the process (and when you have knee problems, it is definitely a process) of sitting down or standing up; there is a HUGE reduction in pain.
I just walked around a Costco for almost two hours, and I'm feeling maybe 1/4 the pain I would have without the straps.... more importantly, I was able to make it through the whole shopping trip. Usually about half way in I have to go sit down.
I can't wait to get the full braces.
