A Platelet-Rich Plasma Injection into the Sectioned Achilles Tendon of a Rat04:31

A Platelet-Rich Plasma Injection into the Sectioned Achilles Tendon of a Rat

459
This video demonstrates a technique for injecting platelet-rich plasma (PRP) into the sectioned Achilles tendon of rats. A small segment is excised from the Achilles tendon of a recipient rat, the site is sutured, and the rat is allowed to recover. Concurrently, whole blood is collected from a donor rat and centrifuged to obtain PRP, which is then activated and injected into the sutured site of the recipient rat to induce tendon...

Ultrasound Tissue Characterization of Human Achilles Tendon by Stability Quantification of Echo Patterns

462
Ultrasound is the approach most commonly adopted in the clinical setting for the assessment of the size and structure of the Achilles tendon. To expand the Achilles tendon assessment in a more comprehensive manner, the ultrasound tissue characterization (UTC) approach has recently been proposed and validated in clinical...

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Radiology

Background:

  • The Achilles tendon is crucial for locomotion, and its rupture severely impacts mobility.
  • Clinical diagnosis of Achilles tendon rupture can be challenging due to factors like hematoma.
  • Imaging modalities are essential for accurate assessment and treatment planning.

Purpose of the Study:

  • To evaluate the role of sonography and MRI in diagnosing Achilles tendon ruptures.
  • To assess the effectiveness of imaging in guiding treatment decisions.
  • To monitor the healing process of Achilles tendon ruptures using sonography.

Main Methods:

  • Clinical examination including Thompson test and one-leg heel raise.
  • Dynamic sonography to assess tendon end adaptation and localization.
  • Magnetic resonance imaging (MRI) for detailed tendon structure evaluation.
  • Sonographic follow-up examinations at 4 and 8 weeks post-treatment.

Main Results:

  • Sonography effectively determines rupture localization and dynamic tendon end adaptation.
  • Complete adaptation of tendon ends suggests suitability for conservative treatment.
  • Sonographic follow-up shows increased volume at the rupture site, indicating normal healing.
  • MRI verifies rupture and provides detailed structural information.

Conclusions:

  • Sonography and MRI are valuable tools for diagnosing Achilles tendon ruptures.
  • Imaging guides the choice between conservative and surgical management.
  • Serial sonography effectively monitors the healing trajectory of Achilles tendon ruptures.
