Pseudotumor in Ceramic-on-Ceramic Total Hip Arthroplasty: A Case Report.

Pseudotumors are a rare complication of total hip arthroplasty (THA), arising from local soft tissue reactions. These reactions can lead to painful joint effusions and prosthetic loosening, often necessitating revision surgery. Metal-on-metal and metal-on-polyethylene prostheses are particularly prone to this complication due to the accumulation of metal debris from prosthetic wear, which represents a significant drawback.
