My knob is loose ! It revolves when before it was a nice firm knob.

I'm talking about my gear knob of course - what else! I have removed it and screwed it back on but it still rotates. I find this distracting whilst driving but I can't see how to fix it.

Is there a solution or do I need a new knob? This looks like the one on my Roadster -
