Cadaveric study reveals significant safety differences between medial midline portal and anterocentral portal, suggesting optimal choices for ankle procedures.
Key Points
The anterocentral portal shows greater safety compared to the medial midline portal, minimizing tendon injury.
Injuries were noted during medial midline portal placement, impacting the extensor hallucis longus tendon in two cadaver specimens.
Anatomical measurements revealed the medial midline portal was closer to vital structures, increasing the risk of injury.
This cadaveric study provides critical insights into the anatomical safety of different portals in ankle arthroscopy.
