The present study examined the short-term results of CentPillar cementless total hip arthroplasty (THA) using the GB HA and TMZF HA stems. We treated 31 patients during the period between January 2005 and June 2009. The average age of the patients at the time of surgery was 54 years, and the average postoperative follow-up period was 13 months. Early stem subsidence after surgery was significantly less frequent for the TMZF HA stem than for the GB HA stem. In particular, early stem subsidence was detected in cases of varus or valgus stem alignment. The change in stem alignment after surgery using the TMZF HA stem was smaller than that for the GB HA stem. There was no significant difference in the stem-occupation rate in the canal between the two stem types. The average Japanese Orthopaedic Association hip score improved significantly after surgery with both types of stem. The CentPillar TMZF HA stem achieved initial stability of the proximal femur as a result of smaller stem subsidence by coating the PureFix HA with plasma spray.
