Meh.
You can walk, probably even play, with joints that are bone on bone. You’ll pay a price. Price will be pain now, more later, until you get surgical repair which means replacement. How bad the pain is, and how much it affects your performance, depends on individual situation. Every patient is different. Every joint is different.
I’m speaking from personal experience. I have both knees and both hips replaced. I’ve walked around on bone on bone joints. My experience was *not* “excruciatingly painful” (that was rehabbing the cadaver ACL implant years earlier). Every joint is different.
