When would I be able to walk after surgery on my leg?

March of 2010 I broke my femur in a car accident and had to have a rod put in my leg. In about a month I am going to have surgery to cut out a bone spur. They said it would require a bigger insision than what it took to put the rod in my leg. After the last surgery I was walking without crutches in about 3 weeks. They said I would need about a week of doing pretty much nothing I was wondering if after that week I would be back up on my feet or if I would need crutches fir a while after that. Also how long would it be before I could go out and find a job
