One of the most common concerns I hear after hip replacement surgery is that one leg feels longer than the other. This actually occurs because of the tilt of your pelvis after surgery. The muscles around the new hip are not working properly and are not holding your pelvis up therefore, you may still notice a limp or a sag to the operative side. This would make the leg feel longer. As you continue your physical therapy and strengthen the muscles around your hip, you’ll notice over a six, eight, or even ten week period that the hips start to feel equal, and, therefore, the leg length appears the same. Please be patient and certainly ask your surgeon if your concerned about a leg that longer than the other.
