Summary
Total ankle arthroplasty outcomes lack consistent reporting across studies. Standardizing outcome measures is crucial for comparing total ankle replacement effectiveness and improving patient care.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total ankle arthroplasty (TAA) is increasingly used for ankle arthritis.
- Current literature on TAA exhibits significant heterogeneity in outcome reporting.
Purpose of the Study:
- To systematically review outcome reporting measures in prospective TAA studies.
- To identify inconsistencies in outcome assessment in TAA literature.
Main Methods:
- Systematic review following PRISMA guidelines.
- Analysis of 43 prospective studies and RCTs on TAA published in high-impact journals (2009-2020).
- Categorization of outcome measures into pain, function, satisfaction, complications, survivorship, and imaging.
Main Results:
- Post-surgical complications were the most frequently reported outcome.
- No study reported on all seven assessed outcome categories; 51.2% reported on four or more.
- Significant variability observed in patient-reported outcome measures (PROMs) for subjective function.
Conclusions:
- Despite comprehensive studies, inconsistent outcome reporting hinders direct comparison of TAA results.
- Standardized outcome reporting is recommended to facilitate evidence synthesis and clinical decision-making for TAA.
- Improved consistency in reporting will aid in evaluating evolving TAA techniques and patient outcomes.
