Q

Morton, Vet Surg, 2015:
Polyethylene terephthalate prosthesis as a gastrocnemius tendon implant

  1. Features of the implant?
  2. What was the mechanism of failure in the constructs tested?
A

Morton, Vet Surg, 2015:

  1. The implant is biocompatible, encourages anatomic ingrowth, and is enclosed within the paratendon so that tendon gliding is not compromised
  2. The implant itself failed before distal fixation failure in 67% of the constructs

A continuous epitendinous suture as an adjunct to a three-loop pulley suture vs a locking loop suture for superficial digital flexor tendonorrhaphy

A

Putterman, Vet Surg, 2019:

  1. Gap formation was best prevented with a three-loop pulley compared with a locking loop suture
