Why does my knee turn purple/blue?

When my left knee gets cold, for some reason it turns purple/blue. It has done it all my life, and it even happens in the summer too. But in the winter it will get so cold I start to limp. And another weird thing about the same left knee is that there is less hair on it than my right knee. So what do you think could be the problem if anyone has ideas? Jw.
