In spite of this, several complications although not very frequent may exist diminishing this improvement. The postoperative pain is one of them. This case study shows the case of a female patient whom after protesic replacement presented a pattern of postoperative pain over the lateral face of the thigh. After the patient's exploration it was found that the pain was caused by the presence of active myofascial trigger points in the gluteus minor (anterior myofascial trigger point) and in the external vastus lateralis (myofascial trigger points 4). The pattern of pain dissapeared after carrying out a treatment based in the deactivation of the myofascial trigger points. All these facts may relate the possible importance of the myofascial pain syndrome with the postoperative pain after the protesic replacement of the hip.
