Patellar Tendon Repair Using a Patellar Tendon Allograft and External Fixator in Three Dogs

Abstract
Objective The aim of this study was to report on complications and outcomes with repair of ruptured canine patellar tendons using primary tenorrhaphy coupled with patellar tendon allograft transplantation and use of a transarticular external skeletal fixator.
Materials and Methods This report includes three dogs with acutely ruptured patellar tendons, all of whom had surgical repair using a patellar tendon allograft. Dogs were assessed postoperatively by physical examination, owner input, and/or video review. Functional outcomes were classified as full, acceptable, or unacceptable based on previously established criteria.
Results Follow-up time was between 24 and 46 weeks. Two dogs obtained full function and one dog reached acceptable function. The acrylic connecting bars of the external fixator fractured and needed to be replaced in one dog. There were no other problems or complications. There was no evidence of rejection of any allograft.
Clinical Significance Primary tenorrhaphy supported by patellar tendon allograft transplantation and transarticular skeletal fixation appears to be a viable option without evidence of patellar tendon allograft rejection and acceptable or full recovery in the three dogs of this report.
