<p begin="00:00:09.961" end="00:00:12.478" style="s2">- Next we're going to<br />view the patella tendon</p>
<p begin="00:00:12.478" end="00:00:14.561" style="s2">in its longitudinal view.</p>
<p begin="00:00:15.568" end="00:00:19.401" style="s2">I'm going to place the<br />transducer just beneath</p>
<p begin="00:00:20.518" end="00:00:23.988" style="s2">the patient's patella, maintaining contact</p>
<p begin="00:00:23.988" end="00:00:25.821" style="s2">on the patient's knee.</p>
<p begin="00:00:26.918" end="00:00:29.447" style="s2">Here we see the fibers<br />of the patellar tendon,</p>
<p begin="00:00:29.447" end="00:00:31.794" style="s2">attaching on the patella.</p>
<p begin="00:00:31.794" end="00:00:34.143" style="s2">Next we're going to follow<br />these fibers distally</p>
<p begin="00:00:34.143" end="00:00:37.153" style="s2">as they attach on the tibial tubercle.</p>
<p begin="00:00:37.153" end="00:00:38.621" style="s2">And here we see the distal attachment</p>
<p begin="00:00:38.621" end="00:00:40.538" style="s2">on the tibial tubercle.</p>
<p begin="00:00:42.457" end="00:00:46.162" style="s2">Generally, I'll scan the<br />patellar tendon three times,</p>
<p begin="00:00:46.162" end="00:00:49.530" style="s2">once in the center, and<br />then once to each side,</p>
<p begin="00:00:49.530" end="00:00:51.869" style="s2">to view the entire tendon.</p>
<p begin="00:00:51.869" end="00:00:55.286" style="s2">In this case medially and next laterally.</p>
<p begin="00:01:05.601" end="00:01:07.440" style="s2">Next we're going to<br />view the patellar tendon</p>
<p begin="00:01:07.440" end="00:01:09.812" style="s2">in cross-sectional view.</p>
<p begin="00:01:09.812" end="00:01:11.617" style="s2">I'm going to place the transducer</p>
<p begin="00:01:11.617" end="00:01:14.824" style="s2">beneath the patient's patella,</p>
<p begin="00:01:14.824" end="00:01:17.741" style="s2">just overlying the patellar tendon.</p>
<p begin="00:01:19.514" end="00:01:22.200" style="s2">In here we're going to<br />see a circular pattern</p>
<p begin="00:01:22.200" end="00:01:24.182" style="s2">of the patellar tendon in cross-section,</p>
<p begin="00:01:24.182" end="00:01:26.881" style="s2">looking for any abnormalities.</p>
<p begin="00:01:26.881" end="00:01:29.906" style="s2">I'm going to scan distally<br />down to the tibial tubercle,</p>
<p begin="00:01:29.906" end="00:01:32.374" style="s2">slowly looking for irregularities.</p>
<p begin="00:01:32.374" end="00:01:34.045" style="s2">We'll begin to see the<br />tendon slowly disappearing</p>
<p begin="00:01:34.045" end="00:01:36.545" style="s2">and into the tibial tubercle.</p>
