Adverse tissue reactions after total hip arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomaterials Science
• Pathology

Background:

• Hip arthroplasty is a common procedure for hip disease, with generally high success rates.
• Prosthesis failure necessitates revision surgery in a subset of patients.
• Histopathological findings in failed hip arthroplasty tissues are often nonspecific.

Purpose of the Study:

• To review the etiologies of hip prosthesis failure.
• To discuss adverse tissue reactions associated with prosthesis failure.
• To highlight aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL) as a key diagnostic consideration.

Main Methods:

• Literature review focusing on hip arthroplasty failure.
• Analysis of histopathological findings in periprosthetic tissues.
• Proposal of a diagnostic algorithm integrating clinical and histopathological data.

Main Results:

• A variety of microscopic findings are associated with hip prosthesis failure.
• Aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL) is a significant finding, potentially driven by a type VI hypersensitivity to metal ions.
• A proposed diagnostic algorithm aids in identifying etiologic causes of failure.

Conclusions:

• Understanding the diverse etiologies and tissue reactions in hip arthroplasty failure is crucial for revision surgery.
• Aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL) warrants consideration due to its proposed hypersensitivity mechanism.
• The proposed diagnostic algorithm offers a structured approach to identifying causes of prosthesis failure in the absence of nomenclature consensus.
