excellent

The awkward part of this Alignment view is that it shows the gentiles shape, I don't feel comfortable showing it to the doc? Any advice?😅

[@heribertdichter2838]

Would love to get the same for the sagital and horizontal plane

[@dagourdis]

Excelent

[@mirthanvi]

Sir what is the highest varus you had to keep in a constitutional varus patient?

[@drkosh]

I think your assertion that internal rotation of the femoral component is a prob has been proven incorrect. This classification only addresses the alignment is extension - any thought on the flexion alignment in the coronal plane which completes the kinematic arc of the knee in its dynamic state

[@brucetowell3432]

Dr. This question might be for a foot surgeon but I'll start with you, if I may? I'm a 70 year old male who's had a tendon problem in my foot from running back when I was in my 30's and 40's. A foot surgeon stated I needed a "triple achilles something or other, but cannot recall the exact er he used. Question, if this was my only problem fine, I'd get the surgery, but I also need to have knee replacement surgery on the same left leg as my bad ankle!! Also my right knee needs the same surgery but it might not be total. So I'm looking at 3 operations!!, In what order SHOULD i get them done? My guess would be 1.) left ankle first 2.) right knee next then 3.) left knee.....How should I proceed? thanks warm regards Bruce Amherst, Ohio

Bruce your thought process is correct, build the foundation at the left ankle, tackle the right knee which might only need a partial knee replacement and could be a faster recovery and then the left total knee.
