Symptomatic Periarticular Fluid Collection After Total Hip Arthroplasty: Septic or Aseptic Complication? A Case Report and Literature Review.

ABSTRACT: Background and Clinical Significance: Adverse reactions to metal debris (ARMD) are a rare but increasingly recognized complication following total hip arthroplasty (THA), with some studies suggesting upwards of 5% of metal-on-metal (MoM) and 3% of metal-on-polyethylene (MoP) prostheses being attributed to this. Historically, metallosis due to MoM implant design was the primary cause of ARMD. However, ARMD can also arise in metal-on-polyethylene (MoP) prostheses due to trunnionosis, which involves wear and corrosion at the modular femoral head-neck interface. Clinically, ARMD can resemble periprosthetic joint infection (PJI), complicating both diagnosis and management. Case Presentation: We present the case of a 40-year-old female with a history of systemic degenerative joint
