Metal Hypersensitivity After Joint Arthroplasty

Metal Hypersensitivity Reactions Following Total Joint Arthroplasty

Total joint arthroplasty (TJA) is a widely performed surgical procedure that involves replacing a damaged joint with a prosthesis made of metal alloys, polymers, and ceramics. While TJA has significantly improved the quality of life for many patients with end-stage joint disease, metal hypersensitivity reactions have emerged as a potential complication. This comprehensive review aims to investigate the prevalence and clinical significance of metal hypersensitivity reactions following TJA, discuss diagnostic methods, and explore treatment options for affected patients.

Prevalence of Metal Hypersensitivity Reactions

Metal hypersensitivity in the context of TJA is a relatively … Read more

Aseptic Loosening in Joint Arthroplasty

Aseptic Loosening in Total Joint Arthroplasty

Aseptic loosening is a major long-term complication of total joint arthroplasty (TJA), encompassing both total hip arthroplasty (THA) and total knee arthroplasty (TKA). This condition involves the loosening of the prosthetic implant from the bone without any signs of infection. Aseptic loosening can cause pain, instability, and functional impairment, often necessitating revision surgery1. This article delves into the mechanisms of aseptic loosening, explores diagnostic imaging techniques, and outlines treatment options.

Mechanisms of Aseptic Loosening

Aseptic loosening primarily stems from the body’s inflammatory response to wear debris generated by the implant. These particles … Read more
