I am left-handed and now its almost like I am ambidextrous as well now since I have been going to BOM classes. Teacher has been teaching us to use both hands and feet when quilting, cutting, and sewing. Hey practice makes perfect Before your surgery start practicing You will be amazed at how easy it comes to you
ps good luck on your surgery I had mine done 10 years ago but into 2 yrs I fell and broke the femur bone on my total knee doctor told me the knee was not moving and thats why my femur broke but that when I do something I do it well a 45 degree brake all the way to my hip however back to your left right question work with it before you have your surgery
