Usually the feeling goes away. Feeling that the new leg is longer is common after a hip replacement, and in most people it fades or disappears during the first year.

It can be either. Sometimes the leg really is a little longer. Surgeons aim for equal lengths, but a hip that is set too short is more likely to dislocate, so a little extra length is sometimes accepted to keep it stable. The bigger the real difference, the more likely people are to feel it.

What your legs were like before surgery matters too. People who had a bigger difference beforehand, or a bigger correction during surgery, are more likely to notice a difference afterward. A large difference is not always fully corrected, because stretching a leg a long way has been linked to nerve injury in some studies, though not all.

Often, though, the feeling does not match the X-ray. A tilted pelvis or a stiff lower back can make a leg feel longer than it measures. The hip muscles on the operated side also often stay weaker for months or longer, which can let the pelvis tilt when you walk. Whether that weakness causes the feeling has not been studied directly.

Most people whose feeling does not go away are still satisfied with their hip.

In general:

  • Give it time. The first months are not the final answer.
  • If it has not settled, ask your surgeon to measure the lengths.
  • A real difference that stays is usually treated with a lift in the shoe first.
  • When that does not help, a second operation to correct the length is sometimes an option.
