Purpose This study was designed to evaluate the effect of distal stem migration of a cementless femoral component on the functional outcome of patient over the period of 1 year after unilateral total hip replacement Methods In this retrospective cohort study, migration patterns for 50 implants and functional outcome of patients were analysed. In all cases collarless uncemented stems were used. Results The mean follow-up was 12 months. Xray evaluations revealed a mean subsidence of 0.36 mm after one year. Postoperatively the total Harris hip mean score was 90.83. Conclusion functional outcome improves after total hip replacement whereas no significant change in functional outcome was seen in patients with subsidence<2 mm when compared with patients without subsidence. Further studies are needed to confirm our findings.
