Outcomes of Revision Total Ankle Replacement.

Area of Science:

• Orthopedic Surgery
• Arthroplasty
• Biomedical Engineering

Background:

• Total ankle arthroplasty (TAA) is a common procedure for end-stage ankle arthritis.
• Revision TAA is performed to address complications or failures of primary TAA.
• Understanding the outcomes of revision TAA is crucial for patient selection and surgical planning.

Purpose of the Study:

• To conduct an up-to-date review of the outcomes associated with revision total ankle arthroplasty (TAA).
• To synthesize current evidence on survival rates, reoperation rates, and functional outcomes following revision TAA.

Main Methods:

• A systematic review of relevant studies published within the last decade.
• Inclusion of twelve studies that met the predefined criteria.
• Analysis of data including patient-reported outcome measures, survival rates, reoperation rates, and alignment.

Main Results:

• Median survival rate of 86% at a median follow-up of 4 years.
• Median reoperation rate of 16% within the follow-up period.
• Significant improvements in patient-reported outcome measures were noted in 6 studies, while significant alignment improvement was documented in only 1 study.

Conclusions:

• Revision TAA is a safe procedure that can yield favorable outcomes, particularly in terms of patient-reported function.
• While functional outcomes show improvement, the impact on long-term alignment requires further investigation.
• Limited quantity and duration of long-term outcome data necessitate continued research in this area.
