The patient has injured his right Achilles tendon a few weeks ago which was treated conservatively. The patient reports no pain (VAS: 0) but a considerable loss of strength. The patient sports a lot. The left Achilles tendon is asymptomatic.
Analyzing the images according to the SonoSkills pathology checklist the following items are being scored:
- Shape: the tendon has increased in cross sectional area and thickness (L: 6,1 mm versus R: 15,3 mm); the paratenon shows an increase of thickness as well (L: 0,88 mm versus R: 1,6 mm).
- Echogenicity: a large anechoic zone can be seen mid tendon which appears to be an effusion. Parts of the tendon and the paratenon both have a hypoechoic appearance. A part of the tendon is hyperechoic due to the acoustic enhancement artifact.
- Continuity: a large zone in the Achilles tendon shows no continuity of fibers (approx. 24,5 x 8,0 x 12,3 mm). The tendon is compressible.
- Doppler: a light to moderate positive power Doppler signal can be seen.
- Function: no clips where made of ultrasound visualized Achilles tendon loading.
