For anybody that’s still curious about adult O-S, I had it when I was a teen, but the bump persisted into adulthood. Then a couple of years ago I had knee surgery and after it was done, the surgeon commented that he went ahead and removed the O-S while he was in there. Now one knee has the bump, the other doesn’t.
And he has mine!
