Hi. I Am A 50 Year Old Woman With Avascular

Hi. I am a 50 year old woman with avascular necrosis. In 2014, I had both hips replaced. I had my left shoulder replaced in November of 2014 and am now preparing for my right shoulder replacement in July. I do not fit any of the criteria for this condition. My knees have been bothering me lately. My question is: Is this a common thing to happen to a person that all of these joints need to be replaced?
