Place du traitement médical dans la prise en charge des infections articulaires sur prothèse

Long-term ambulatory antibiotic therapy can be prescribed in the absence of signs of prosthetic loosening in the case of hip or shoulder infection, with staphylococci or enterobacteria or Pseudomonas. Debridement with retention is proposed for patients with an early postoperative or acute haematogenous infection if the duration of signs is less than three weeks and the soft tissue is in good condition. Replacement arthroplasty should be preferred in the case of prosthetic loosening or knee prosthesis. The choice of a one-stage or two-stage exchange depends on the initial efficacy of the antibiotic therapy, of the soft tissue and the general conditions.
