Classification of Parvizi et al for Periprosthetic Joint Infection (PJI) Based on Time and Nature of Presentation

Description

Parvizi et al classified periprosthetic joint infections (PJI) based on the time and nature of the presentation relative to the original surgery. The authors are from Thomas Jefferson University in Philadelphia.

Patient selection: prosthetic joint present

Parameters:

(1) time of onset relative to joint replacement surgery

(2) nature of the clinical presentation

Time of Onset	Designation
< 3 months (< 90 days)	early
3 to 12 months	delayed
> 12 months	late

Nature of Presentation	Designation
sudden onset, erythema, edema, warmth, tenderness	acute
joint pain, stiffness, sinus tract	chronic

Onset	Nature	Source	Virulence
early	acute	intraoperative contamination; postoperative wound dehiscence	high
delayed	chronic	intraoperative contamination	low
late	acute	hematogenous seeding	high
late	chronic	intraoperative contamination	low

where:

• Staphylococcus aureus would be an example of a high virulence bacteria.

• Transient bacteremia with a low virulence bacteria could present as a late PJI.
