Abstract

Objective: To evaluate the use of a single-portal endoscopic desmotomy of the PAL with the use of Arthrex - Centerline ™
Study Design: Cadaveric Study
Animals: Equine distal front limbs (n=10)
Methods: A dual-port endoscopic desmotomy with a hook knife was performed in 5 specimens (Group A) and single port Arthrex - Centerline ™ Desmotomy was performed in another 5 specimens (Group B). The performing time, judgments of the surgeon, number of blade passages, and gross anatomy were evaluated.
Results: The performing time and surgeon judgments were significantly lower in Group B. No significant differences were assessed in number of passages to achieve a complete PAL resection and a gross anatomy evaluation.
Conclusions: The use of Arthrex - Centerline ™ is feasible for a PAL desmotomy procedure. It was faster with more handling ease compared with the free-hand double-portal desmotomy and allowed the same results in terms of number of passages to complete the release evaluated at gross anatomy.
