Answer

Three major types of prosthetic joint infections exist: (1) those that occur early, within 3 months of implantation; (2) those that are delayed, within 3-24 months of implantation; and (3) those that occur later than 24 months following the implantation. Most cases of early prosthetic joint infection are caused by S aureus, whereas delayed infections are due to coagulase-negative S aureus (CoNS) and gram-negative aerobes. Both of these types are acquired in the operating room. Late cases of prosthetic joint infection are secondary to hematogenous spread from various infectious foci. [16]
