Summary

Varus positioning is the most common femoral malposition in total hip arthroplasty (THA). The aim of this study was to compare the long-term results of an anatomical cementless femoral stem positioned in varus with those in neutral alignment.

Detailed description

Data were prospectively collected and retrospectively reviewed for all patients who received a cementless anatomical femoral stem in THA between 1998 and 2008. After exclusion criteria applied, 127 stems had an varus axis deviated by more than 3 degrees (varus group) and 156 had an alignment between 0 and 2.9° from the femoral axis (neutral group). Survivorship rates, complications, clinical scores, thigh pain, radiological score, cortical hypertrophy and filling rate were analyzed. Mean follow-up was 10 years.
