Hi and thanks for the good wishes. Life goes and and I have tons to be thankful for.
Partials make sense to some but not sure literature supports them. My surgeon scoffed at them and he's one of the leading surgeons for TKR in the country (NYC). A good friend did two partials and is now facing totals. Some surgeons do one or the other. One key is experience so important selected surgeon have done enough whatever that number is.
Are you doing one or both? Great you are in good condition as that should mean better chance of positive outcomes. Delighted you have decided on a course. Based on your posts am confident you will fare well.
Please let us know how it goes.
