CONCLUSION
• Contamination usually occurs during the
intraoperative period but less frequently
post surgery.
• Hematogenous septic arthritis is not fre-
quent. The prognosis is poor, leading to total
knee revision [15].
• In acute infection, synovectomy with
retention of the implant and PE changing
gives satisfactory results if it is performed
within 2 weeks after the outset of infection
and if there is no radiological signs of
bony infection.
• In chronic infection, the 2 stages reimplan-
tation is our preferred technique.
Future perspectives:
• Molecular diagnosis techniques.
• Research towards the prevention of biofilm
formation (through implant surface coatings).
• More effective antibiotherapy.
• Decrease length of stay (preventing
Oxacilline Resistant Infection).
• Centralization of the information.
• Two-stage revision vs one-stage procedure:
indications? [16].
