You may be quite right. In a small number of patients after total hip replacement the leg either is longer or seems longer. An X-ray and exam are needed to find out for sure.

If the leg is truly longer than the other one, the doctor will see this on X-ray. Sometimes this can happen because of the implant. Usually the patient has pain along the outside of the hip or around the incision. The pelvis drops on the short side to make up the difference. A shoe lift may be all that's needed.

If the legs are truly equal in length on X-ray then the problem is considered called a functionalleg length difference. This means the soft tissues around the hip are tight or off-balance pulling the leg up or down. In these cases physical therapy may be helpful. An aggressive program of stretching and/or strengthening may restore limb length and function.
