[Painful total hip arthroplasty]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Total hip arthroplasty (THA) is a highly successful procedure for improving patient function and alleviating joint pain.
• Despite high success rates, a subset of patients experience persistent or secondary pain post-THA, necessitating revision surgery.
• Unaddressed pain after THA can significantly impact patient quality of life and healthcare resource utilization.

Purpose of the Study:

• To present a structured approach for diagnosing and managing persistent pain after total hip arthroplasty.
• To guide clinicians in identifying the causes of treatment failure and optimizing revision strategies.
• To improve outcomes for patients experiencing residual or secondary pain following hip replacement.

Main Methods:

• Systematic review of diagnostic modalities for post-THA pain.
• Analysis of therapeutic interventions for revision hip surgery.
• Clinical case study review to illustrate diagnostic and therapeutic pathways.

Main Results:

• Accurate diagnosis is crucial for successful revision surgery; empirical revisions often yield poor results.
• Common causes of persistent pain include infection, aseptic loosening, instability, and periprosthetic fractures.
• A stepwise diagnostic approach involving imaging, laboratory tests, and clinical assessment is effective.

Conclusions:

• Effective management of post-total hip arthroplasty pain requires a precise diagnosis before considering revision.
• A multidisciplinary approach and tailored therapeutic strategies are essential for optimizing outcomes in revision hip surgery.
• Further research into novel diagnostic tools and treatment options for persistent pain after THA is warranted.
