I did, Jason - not clunking, but what I called dislocating, since I've had that in other parts of me and it felt exactly the same.
With my first one I didn't notice it clunking or anything, but it did start dislocating after a while. I first noticed it when moving my oldest into her dorm room at college.
I was running the stairs with crates on my shoulders, then raising her bed to allow her to have storage under it, when my hip just sort of slipped out. I couldn't put pressure enough on it to stand well, tried to walk and couldn't and was just standing there perplexed while my daughter asked me what was wrong.
I finally twisted my hip inwards and it popped back into place. I could walk again, thankfully all of her crates and things had been moved in, so all I had to do was to walk down four flights of stairs, then drive two hours home.
I guess my point is that grumpy pain is the main thread, but with the loss of cartilage, the bone spurs, etc. I was also being structurally destabilized. The "dislocations" continued, becoming more frequent and I adapted.
Being naturally stubborn and obtuse, I kept up my activities, playing soccer, dislocating, popping the hip back in and resuming. It became scary when I woke up with it in that position, then tried for a half hour to 'pop it back in'.
There's no prediction of the progression of OA, I guess. which areas lose cartilage and the effect structurally as the degradation continues. So clunking may be part of it for some of us.
Has Mr. McMinn looked at it?
