I am 5 weeks post THR on the left, posterior approach. My doctor said I should be able to go back to work in 6 weeks, but I took off 8 weeks. I have three weeks to go to return to work, but am having doubts about my stamina. I work in a hospital and have to walk a lot. During a typical day, I walk 4,000 to 6,000 steps. I finally got to 1200 steps yesterday, and feel like it would be a miracle to work up to 4,000 steps in the next 3 weeks. My physical therapist says I 'may be' ready to return to work in 3 weeks. I have the ability to take 3 additional weeks off for leave, but feel so guilty. They are really hurting without me. When have you been able to return to a high walk demand job after surgery?
