Recurrent posterior dislocation occurs after primary total hip arthroplasty at rates of up to 7%. Component revision is regarded as standard management, but this major surgery may be unsuitable for elderly patients. We have developed a congruent polyethylene acetabular posterior lip augmentation device (PLAD) with a stainless steel backing plate. This can be used when there is no gross malalignment, wear or loosening of the primary components. We retrospectively compared 20 patients who had revision surgery with twenty patients who had been treated with the PLAD for recurrent posterior dislocation after primary Charnley total hip arthroplasty. In the PLAD group, the mean operative time, intra-operative blood loss, time spent in the high-dependency unit (HDU), transfusion requirements and the duration of hospital stay were all less than that in the revision group. There was no difference in the Oxford Hip Score between the groups at latest review 2 years after surgery. None of the patients in either group had suffered another dislocation.
