Preoperative anaemia and newly diagnosed cancer 1 year after elective total hip and knee arthroplasty

Preoperative anaemia is a well‐established risk factor for use of blood transfusions and postoperative morbidity. Consequently, focus on preoperative evaluation of haemoglobin levels is increasing. In this context, iron deficiency anaemia may be a symptom of undiscovered gastrointestinal (GI) cancer requiring further investigation. However, the association between preoperative anaemia and cancer 1 year after elective total hip (THA) and total knee arthroplasty (TKA) is unknown. We evaluated 1‐year cancer diagnoses, particularly GI cancers, in anaemic and non‐anaemic THA and TKA patients.
