To synthesize evidence comparing ultrasound-derived assessments of talar cartilage morphology and deformation between individuals with chronic ankle instability (CAI) and those without, and to examine associations between ultrasound measures and specific functional outcomes such as postural control and joint mechanics.
Key Findings:
Ultrasound shows strong correlations with MRI for cartilage thickness measurements, indicating its potential as a reliable assessment tool.
Excellent test-retest reliability for B-mode ultrasonography in assessing talar cartilage thickness, supporting its use in clinical settings.
Limited exploration of ultrasound's utility in detecting talar cartilage changes under mechanical loading conditions, highlighting a gap for future research.
Interpretation:
Ultrasound is a promising, cost-effective alternative to MRI for evaluating talar cartilage in CAI, with the potential to enhance clinical assessments and guide treatment decisions, but further research is needed to fully establish its clinical utility.
Limitations:
Substantial methodological heterogeneity across included studies may limit the generalizability of findings.
Limited studies specifically examining ultrasound under mechanical loading conditions restrict understanding of its full capabilities.
Conclusion:
Ultrasound may provide valuable insights into talar cartilage health in CAI patients, warranting further investigation to enhance its application in clinical settings and improve patient outcomes.
