Several investigators reported that pseudotumor or adverse local tissue reaction (ALTR) occurred after total hip arthroplasty. Our study indicated that 6 degree polished titanium taper with smaller size or cobalt chromium (CoCr) femoral head had no ALTR compared to 12/14 taper rough surface finished taper junction with large diameter femoral head. These phenomena should be analyzed with cobalt chromium alloy trunnion taper fretting or crevice corrosion with titanium alloy femoral stem and CoCr head.
