It is not a bad surgery, fairly easy stuff! Only used the crutches first day, no brace on mine. You will be fine for the wedding, except for maybe the shoes. You may want to find some flat sandals to wear instead. I had the surgery done in May last year and had the hardest time wearing even low heels for a wedding in July. It's because of the angle of how you stand. I was fine in flats but even my low heels made it miserable.
I have my first grandbaby due about 4 weeks after my surgery this April. I am confident that I will be able to walk but not sure how much I can spend on my feet. This time I will lose 100% of the Meniscus. It is my right knee, it was this same knee last May. My recovery may be slightly longer this time because of how much more they have to clean up and because it is 2 surgeries so close together.
