Methods and materials
21 healthy males (25-30 y.o.) were recruited.
Each participant underwent ultrasound elastography of both patellar and quadriceps tendons.
42 patellar tendons and 42 quadriceps tendons were examined.
Examination was performed with a linear 13 MHz ultrasound transducer (EsaoteMyLab Twice) equipped with strain elastography.
Each tendon was evaluated in passive flexion and passive extension and all tendons had a normal sonographic grey-scale appearence.
For the elastography evalution of patellar tendon,
a ROI was placed over the proximal aspect of the tendon,
just distal to the inferior pole of the patella and an additional ROI of the same size was placed over the adjacent Hoffa’s fat.
For the elastography evaluation of quadriceps tendon,
a ROI was placed over the distal aspect of the tendon,
just proximal to the superior pole of the patella and an additional ROI of the same size was placed over the suprapatellar fat pad.
The ratio between the two ROI (tendon and fat) was calculated.
