Why do I have footdrop after total hip replacement?

Q: I am 42 years old. I underwent total hip joint replacement last year and ended up with a footdrop. The doctor says that it might take up to 12 months for it to come back to normal. What is the approximate recovery time of a footdrop?

A:Footdrop occurring after THR is a result of stretching of sciatic nerve around the hip and it usually resolves within few weeks to few months time.
