Abstract

Short cementless stems in total hip arthroplasty have gained increasing popularity, yet on-going studies of many of these implants are lacking. The aim of this study was to evaluate the minimum 5 year clinical and radiological results of a short, highly porous, single-tapered-wedge cementless femoral implant. A retrospective study of 281 hips in 256 patients who had a minimum 5-year follow-up and underwent primary total hip arthroplasty between 2010 and 2016 were evaluated. Clinical and radiological results, complications, and the presence of postoperative thigh pain were evaluated. The mean follow-up was 8 years (range, 5 to 12 years). Clinically, patients had significant improvement in the average patient-related outcome scores postoperatively (Harris hip score: pre 47 versus post 95, University of California Los Angeles activity scale: pre 4 versus post 6, Western Ontario and McMaster Universities Arthritis Index: pre 51 versus post 3, Short Form (SF)-12 physical component summary : pre 32 versus post 52, Short Form-12 mental component summary: pre 49 versus post 55 (P <.001)). Radiographic signs of ingrowth were present in all hips. There were three patients (1.1%) who developed transient thigh pain postoperatively, all of which resolved with nonoperative management. This study provides the longest follow-up of this short, highly porous, single-tapered-wedge cementless femoral stem in the literature. This short, single-wedge stem with its highly porous coating demonstrated reproducible bone ingrowth in all patients and significant functional improvement with a very low rate of transient thigh pain.
