I had both hips replaced a year and a day between the two. Made life bearable. Now my left knee is begging for relief. I am 73 and had polio as an infant. Totally paralyzed from it. The pain in the knee keeps me too sedentary and the older we get the more risk anesthesia causes brain fog which may not go away. Have your surgeries from a competent surgeon and spare yourself pain, worry, and immobility. Best to you. Would be skeptical about whartons jelly if I had seen the ad.
