Periprosthetic Joint Infection

Adam J Schwartz, MD1, and David Jacofsky, MD2

Periprosthetic joint infection (PJI) is estimated to occur in 1–2% of primary total joint arthroplasty procedures. Infections are classified as acute or chronic based upon timing relative to the index procedure or the onset of symptoms. The treatment options consist of surgical debridement with implant retention, debridement with implant removal, arthrodesis, and, rarely, chronic antibiotic suppression. Amputation is infrequently required for refractory cases. The majority of late PJIs can be successfully managed with a two-stage reimplantation protocol. Adv Orthop 2011;2(4):135–40.
