I had been diagnosed with Osteoarthritis in the left knee and beginning in the right knee four years ago. I was told that I was bone on bone in the left knee. Since I was only 50 years old the doctor said that I was too young for surgery. Four years later, 1 less thyroid, additional weight, I have been told I am too fat and I need to get my BMI down before they would consider. I was told of all these complication yet I know people at lot heavier than me that had it done and the weight was never considered. Please see some opinions or experience reference here. Thanks.
