Glucosamine-will it help my knees

My wife just came in from a 40 minute brisk walk wearing Nikken's Cardiostrides.  I can feel the ache in my left knee which could easily turn into real pain.  I've been taking glucosamine at the suggestion of others. 

I just checked glucosamine in wikipedia and it stated that it was not recommended for use to treat osteoarthritis or to rebuild cartilage in joints.  Boy, there's one whole shelve at Sam's Club in Lansing filled with the supplement.  Is this just a word of mouth thing where somebody said it helps or might help?
