I was in my early 30's and my soccer playing was with my five year old in the back yard. Don't recall any sports issues but at the time, my sports were golf, fishing, XC and enduro motorcycle racing. Not a lot of start/stop stress on the joint. Also, FWIW, at that time I don't think MRI's or arthoscopic surgery were options. We were a much tougher animal then. Or lame. I also tore a shoulder throwing a stone at a tree full of birds without warming up first. A shot of cortesone and I was back in the game. That one only aches every month or so.
