= statistically significant difference in baseline ultrasound measures between participants with and without symptoms at 1 year post-anterior cruciate ligament reconstruction.

^{^}

= effect size indicates large magnitude difference between participants with and without symptoms at 1 year post-anterior cruciate ligament reconstruction.
