A surgical guide can include a first portion comprising an outer surface configured to conform to a portion of an acetabulum of a particular patient. The first portion can be configured to accommodate the ligamentum teres of the patient. The surgical guide can be configured to receive a second portion that includes an alignment portion defining an alignment axis such that when the surgical guide is coupled to the acetabulum the alignment axis is oriented at a predetermined orientation relative to the acetabulum. The second portion can include a depth limiting feature configured to limit insertion of a guide rod along the axis to a patient specific insertion depth.
