==Background==
*U/S can be used to assess continuity of tendons and ligaments
*They have a property called anisotropy which means they have 2 different appearances if assess longitudinally or transversely

==Instructions==
#Use linear probe (high frequency probe)
#Place probe in longitudinal plane over suspect tendon; high yield locations inlcude:
#*Biceps can be proximal or distal
#*Patella tendons 2cm from insertion on patella
#*Achilles 2-6cm above calcaneus
#Fan and slide side to side to optimize your view
#Slide distal to proximal to find defect
#Turn probe 90° to assess for tendon body defects

==Findings==
*Positive Findings
**Discontinuity in longitudinal view of ligament
**Collection of fluid in longitudinal or transverse view suggests injury
*Negative Findings
**Longitudinal views show continuous densely striped parallel lines
**Transverse views show oval structure with punctate interior

==Pearls and Pitfalls==
*Look at other limb for "normal" anatomy
*Have patient range limb and view in real time
*Know your limitations if case is not clear cut
*Do not mistake [https://radiopaedia.org/articles/anisotropy anisotropy] for tendon rupture
