Agree, and I thought he had both hips replaced. I’ve seen some total joint replacements require blood but usually older pts w/complications. Also, when MD farts around during surgery. The excellent surgeons don’t waste time in the operating room. Those that do allow greater time to lapse during surgery, have greater blood loss. . . He could have donated his own blood ahead of surgery and they had devices back then that orthopedic surgeries were using to salvage and filter blood loss for replacement transfusion.
