Introduction:
Total ankle arthroplasty (TAA) has emerged as an alternative to ankle arthrodesis for managing end-stage ankle arthritis. However, the long-term survival of TAA remains inferior to that of hip and knee replacements, leading to a higher rate of revision TAA. Understanding the indications and outcomes of revision procedures is critical for orthopedic surgeons managing complex ankle pathology.
Areas Covered:
This review explores the indications, surgical considerations, and outcomes associated with revision TAA. A structured literature search was conducted using PubMed and Scopus (January 2000-March 2024) with keywords including 'revision total ankle arthroplasty,' 'implant failure,' 'complications,' and 'biologic augmentation.'
Expert Opinion:
Revision TAA presents unique surgical and biomechanical challenges that require individualized treatment approaches. While it offers pain relief and functional restoration for select patients, outcomes remain less favorable compared to primary TAA. Future advancements in implant technology may improve long-term success rates. Additionally, optimizing patient selection criteria and perioperative protocols will be essential to reducing complications and enhancing outcomes. Further research is needed to refine revision techniques and establish guidelines for managing failed TAA effectively.
