**2.3 Corticosteroids**

Inclusion of corticosteroids in the local mix is controversial. Periprosthetic infection is a dreaded complication with significant implications for the patient and is of concern with use of corticosteroids given the drug's immunosuppressive properties. Steroids prolong the duration and efficacy of the local mix [24]. A randomised control trial (RCT) showed that adding corticosteroid to the local anaesthetic cocktail improved 24 hour post-operative pain with no increased complications for 12-months, including deep infections [25].
