title: Treatment of anaemia after joint replacement. A double-blind, randomised, controlled trial of ferrous sulphate versus placebo.
abstract: After total hip and knee replacement arthroplasty, patients may become anaemic and may be prescribed oral iron. There is, however, no published evidence that this is of benefit when used postoperatively. We treated 72 patients who were anaemic after primary total hip and knee arthroplasty by randomly allocating them to receive six weeks of either oral ferrous sulphate (35 patients) or a placebo (37 patients). Both groups of patients were similar in all aspects except for the treatment given. There was no statistically significant difference in the change of haemoglobin levels between the two groups. We therefore believe that the prescription of iron to all anaemic patients post-operatively should be avoided. The level of serum ferritin should be monitored at preoperative assessment.
