About The Webinar
This presentation reviews 50 dogs referred to The Ohio State University Veterinary Medical Center for investigation of poor recovery after lateral suture stabilization (LSS) for CCL rupture. Monofilament nylon with crimp was the most commonly used lateral suture material. Arthrotomy for CCL debridement and meniscal inspection was not consistently performed during the initial surgery. Tibial plateau angle was not significantly different to a control population of CCL deficient dogs. 86% of cases had demonstrable cranial drawer but this was not identified as the primary cause of poor function. Incorrect placement of the transverse tibial tunnel was a common technical error. The three most common major complications were medial meniscal rupture (46%), postoperative infection (40%) and medial patellar luxation (24%). More than one problem was identified in 24% of the cases. Selection criteria for LSS and recommendations for initial and revision surgical technique will be discussed.
