@Laura1979, are you using a walker, cane or crutches?
I was using a walker after my first surgery (when I had my femur fracture) and had quite a leg length difference. I continued to use my walker even after my surgeon cleared me to go to full weight bearing. It helped me to feel stable and balanced.
Just take it slowly. If your surgeon has cleared you you'll be okay to carefully try out your new hip and mended femur. Use whatever walking aid makes you feel comfortable. I tried to concentrate on walking with my heel down first and then onto the toe. (I hope that makes sense).
As far as PT goes, you just have to be firmly in control. I can absolutely understand you wanting to get their help with proper walking techniques, etc.
My PT helped with that and with basic exercises for strengthening and stretching. I'm glad I went, but honestly I think I would have gotten to the same place by simply walking as tolerated.
It's hard to say, really. My physical therapist is a lovely person who taught me some great exercises, did terrific massage on my tight hamstring and quad muscles, and did very gentle stretching manipulation with me.
The problem came when the exercise regimen was upped to include a lot of new resistance moves. I just don't think I was ready and I ended up experiencing trochanteric bursitis, which slowed my progress down considerably.
I find that just walking and doing the beginning exercises my therapist taught me works great at keeping me strengthened and slowly improving my range of motion and flexibility.
Everybody has to decide what is best for them physical therapy wise.
Just don't allow yourself to be pushed further than you feel comfortable.
If it hurts, don't do it and don't allow anybody to make you feel badly for saying 'No'.
Listening to your body is key.
You'll be going through a lot of changes as you heal and your body will let you know what it can and cannot tolerate.
Remember, this is a marathon, not a sprint.
