Subject: What makes my ankle pop?

I sprained my ankle a year ago (outside sprain) and it still pops when I 
rotate it.  It's not usually very painful, but the longer my ankle has been 
immobile, the louder and more painful the pop.  Everyone I've talked to 
who's ever sprained an ankle says to experience the same thing, so I'm not 
very concerned about it; I am just curious about what is going on inside my 
ankle that is responsible for the popping sensation,  and are there any 
medical procedures to end it?  Thanks in advance!
