The purpose of this study was to examine clinical outcomes and operative pitfalls of six cases of total hip arthroplasty (THA) surgery after failed transtrochanteric rotational osteotomy (TRO) for avascular necrosis of the femoral head. Five were men and two were women. The average age of the patients at the time of conversion to THA was 40 years (range, 21-60 years). Postoperative Japanese Orthopaedic Association (JOA) scores showed very satisfactory improvement compared to preoperative scores (mean score 40.7/78.5 points, respectively). Compared to the primary THA procedure, the mean operation time of THA after the failed TRO was significantly longer and the average of blood loss was also significantly greater. Postoperative complications were observed in only one hip. The broach should be inserted carefully to avoid retroversion. It is important to completely remove the impingement of the osteophyte. Because in THA after TRO many pitfalls are existing, these points should be taken into preoperative and postoperative consideration.
