Your leg may be longer or shorter than normal following this operation. Every effort will be made to maintain your leg length; however, in your individual situation this may not be possible. Making the hip replacement stable is a key factor to the success of the surgery. Changing the length of the leg will affect the stability of the hip. By increasing the length of the leg, this will tighten the muscles around the hip joint thereby increasing the stability. However, if the leg is too long, this will stretch the nerves and potentially cause nerve damage.
Pain and difficulty walking can result from changes in leg length. However, this can be improved with the use of a shoe lift.
