prosthetic joint

Introduction

• artificial joint from
  • total hip arthroplasty
  • total knee arthroplasty

Diagnostic procedures

• arthrocentesis for inflammatory effusion of prosthetic joint to assess for infected prosthesis
  • a warm, painful, swollen prosthetic joint suggest infected prosthesis if WBC count is > 3000/uL (50,000-100,000 characteristic) with > 75% neutrophils

Complications

• 4-6 weeks of therapy with vancomycin or daptomycin for MRSA bacteremia

• disease interaction(s) of bacteremia with MRSA in patients with prosthetic joint

Management

• prophylactic antibiotics (cefazolin or vancomycin) before high-risk procedures in patients with prosthetic joints
• treatment of infected joint prostheses without removal of the prosthesis may be successful up to 62% of the time
• treat Staphylococcus aureus bacteremia or sepsis with 4-6 weeks of IV antibiotics
  • IV vancomycin or daptomycin for 4-6 weeks
