ACL reconstruction after tummy tuck and breast augmentation?

Hello: I have a question about surgery timing. I am having a tummy tuck and breast augmentation next week. However, I also need an ACL reconstruction, will go with hamstring instead of patellar since the scar will be smaller and I am no longer going to be playing sports that could increase the risk of ligament failure. How soon do doctors recommend having another surgery? I am taking time off from work (vacation accumulation) to get all this done since my knee is no longer stable.
