Slo, I hope you get the results you need from your surgery. My Dad has a lot of feet and knee issues...one foot needs rebuilding-not in his plans because with age and recovery time...he decided not to do it. His crow boot would not work with our knee doctor's suggestion for an off=loading brace.
I chose left foot plus changes. I use a knee sleeve currently on left so it is easier and do right sock right hinge knee brace.
I am discovering a lot of my relatives having right knee issues.
