For instance, patients with
sickle cell disease have been observed to have higher rates of
complications including periprosthetic infection and thrombo-
embolic events [6–11]. Limited data exist comparing in-

of OA and AVN. One matched pair analysis of 188 hips found
similar rates of in hospital complications in THA for OA and
AVN, including deep vein thrombosis, pulmonary embolism,
and infection
