Team Approach: Metal Hypersensitivity in Total Joint Arthroplasty

Area of Science:

• Orthopaedic Surgery
• Immunology
• Materials Science

Background:

• Total joint arthroplasty (TJA) volume is increasing nationwide.
• Uncommon complications like metal implant hypersensitivity are reported more frequently.
• Metal hypersensitivity presents diagnostic challenges due to vague symptoms.

Purpose of the Study:

• To highlight the diagnostic challenges of metal implant hypersensitivity.
• To emphasize the need for a multidisciplinary approach in managing this condition.
• To discuss potential treatment strategies, including revision arthroplasty.

Main Methods:

• Diagnosis of exclusion, requiring thorough evaluation of other potential etiologies.
• Consideration of patient symptomology and implant performance.
• Multidisciplinary team collaboration involving various medical and engineering specialists.

Main Results:

• Metal hypersensitivity can lead to significant patient morbidity and implant failure.
• Refractory cases may necessitate revision arthroplasty and conversion to hypoallergenic implants.
• Successful management relies on a comprehensive, team-based diagnostic and treatment strategy.

Conclusions:

• Metal implant hypersensitivity is an increasingly recognized complication in orthopaedic implants.
• A systematic, exclusionary diagnostic process is crucial.
• Effective treatment mandates a collaborative effort from a diverse group of specialists.
