    Abstract

    Aims: To accurately assess subsidence, rotation and clinical scores in two cementless femoral stems. Methods: 260 patients received either K2 or Apex femoral stems and were studied over 2y, with RSA and clinical scores. Results: Mean Oxford Hip score for both stems was excellent (45.78 and 46.76). Very little subsidence or rotation were noted on RSA in either stem. There were no statistically significant differences in clinical scores, or radiological motion between stems. Revision rate was 0.8% over the study period. Conclusion: Excellent clinical and RSA scores over the 2y study period predict good long term outcomes for these stems. © 2014 .
