The authors hypothesize that asymptomatic structural changes found at the lateral ankle via sonographic examination will be associated with increased risk of future ankle injury.

Aims, purpose, and/or objectives (primary, secondary, and exploratory):

Primary aim: Examine the likelihood of experiencing a time-loss lateral ankle injury in athletes with baseline pre-season ultrasound abnormalities compared to those without abnormalities

Secondary aim: Identify, describe, and report prevalence of pre-season asymptomatic sonographic abnormalities in the structures of the lateral ankle

The purpose of this study is to quantify medial meniscal extrusion with and without a medial knee unloader brace using ultrasonography in patients with isolated medial knee pain.
