LOL I found out who the anesthetist was going to be and on calling his office a woman did check with me which knee it was going to be. So guess there is some insurance there. Have only seen the surgeon once. He telephoned a few days after to ask if i would participate in a research program. After a no hesitation 'be glad to' plunge, i asked what's the project. Using technical terms he said using a robot or not. They are still trying to more accurately determine any differences in average respective outcomes.
