Figure 1.
Sonography images of the patellar tendon (A) Thickness of the patellar tendon (dotted line) was measured from the superior border of the patellar tendon to the tip of the patellar.
(B) Cross-sectional area of the patellar tendon was measured by tracing the outer margin of the patellar tendon (dotted circle) (C) Shear elastic modulus of the patellar tendon was quantified by the elastography. The white circle delineates the area of interest.
