1. A method for orienting an acetabular cup prior to impacting in an acetabulum of a pelvis, comprising:

  • obtaining a cup impactor with a visual guide thereon at a location based on pre-operative planning specific to the patient, the visual guide emitting simultaneously at least two light beams;

    releasably connecting an acetabular cup to an end of the cup impactor;

    seating the cup at the end of the cup impactor in the acetabulum;

    aligning the visual guide with at least two landmarks on the pelvis planned in the pre-operative planning specific to the patient by rotating the cup impactor with the cup seated in the acetabulum until a first of the light beams points a first of the landmarks on the pelvis, and a second of the light beams points a second of the landmarks on the pelvis separate from the first of the landmarks, the first and the second of the light beams being non-parallel to one another; and

    when the visual guide is aligned, impacting the cup into the acetabulum with the cup impactor.
