Hydroxyapatite coated femoral stems in primary total hip arthroplasty: a meta-analysis

Rajiv Gandhi et al. J Arthroplasty. 2009 Jan.

Abstract

We conducted meta-analysis of clinical studies of HA coated femoral stems in hip arthroplasty. After an exhaustive literature search, we abstracted relevant data on the outcomes of stem survival from aseptic loosening and Harris Hip scores. The risk ratios and mean differences with 95% confidence intervals (CI) are reported. 9 studies met our inclusion criteria for the analysis. The cumulative risk ratio for femoral stem survival from aseptic loosening was 1.0 (95% CI: 0.995 to 1.005) P = .98. The pooled mean difference for the Harris Hip scores (HHS) was 0.072 (95% CI: -0.062 to 0.206), P = .293. The results of this study demonstrate that there are no clinical benefits in the use of HA/porous coating over porous coating alone in primary hip arthroplasty.
