DOES IRON SUPPLEMENTATION FOLLOWING TOTAL KNEE OR HIP ARTHROPLASTY ACCELERATE RECOVERY OF HAEMOGLOBIN LEVELS? A RANDOMISED, PLACEBO CONTROLLED STUDY.

7th Congress of the European Federation of National Associations of Orthopaedics and Traumatology, Lisbon - 4-7 June, 2005



Abstract

120 patients undergoing primary TKR/THR were randomised to receive ferrous sulphate (FS) or placebo (P) for three weeks following their arthroplasty. Haemoglobin levels and absolute reticulocyte counts were measured at days 1 and 5, and weeks 3 and 6. Ninety-nine patients FS (50), P (49) completed the study. The two groups differed only in treatment administered. Haemoglobin recovery was similar at day 5 and by week 3, haemoglobin levels recovered to 85% of their pre-operative levels, irrespective of treatment group. A small but greater recovery in haemoglobin level was identified at 6 weeks in the FS group for females (6% Vs 3%) and males (5% Vs 1.5%). The clinical significance of this is questionable and may be outweighed by the high incidence of reported side effects of oral iron, and the economic costs of the medication. Administration of iron supplements following elective TKR or THR does not appear to be a worthwhile practice.
