Patient-Specific vs Standard Instrumentation in Total Ankle Arthroplasty: A Systematic Review and Meta-analysis of Short-term Outcomes

Key Points

• Patient-specific instrumentation shows no significant improvement in functional outcomes, with an unclear revision risk.
• Fluoroscopy time is reduced with patient-specific instrumentation, but sagittal alignment deviation increases.
• Systematic review and meta-analysis evaluate short-term outcomes across various comparative studies, suggesting ongoing uncertainty about effectiveness.
• Future high-quality studies with extended follow-up are crucial to better understand the long-term implications of using patient-specific instrumentation.
