Plain-English summary
A group of large dogs over 100 pounds with torn knee ligaments underwent a surgery called tibial plateau leveling osteotomy (TPLO) to help them walk better. Researchers looked at different types of surgical plates used to fix the knee and found that using a specific plate (the 3.5-mm broad TPLO plate alone) led to fewer complications compared to another type that included a String of Pearls plate. The study suggests that using the simpler plate may be a safer option for large dogs, potentially reducing the risk of problems after surgery.

Abstract
OBJECTIVE: To determine the influence of 3 fixation systems on complications rate after tibial plateau leveling osteotomy (TPLO) in dogs >45.4 kg. STUDY DESIGN: Retrospective case series. SAMPLE POPULATION: Dogs (N = 287, 342 stifles) >45.4 kg with cranial cruciate ligament tear treated with TPLO. METHODS: The medical records of dogs treated with TPLO were reviewed for fixation and postoperative complications, with a follow-up of at least 6 weeks. A random effects logistic regression model was used to evaluate the association between the type of TPLO fixation system and complications. RESULTS: The fixation systems included a 3.5-mm broad TPLO plate alone (8P; 78.4%), a 3.5-mm broad TPLO plate with SOP (String of Pearls) plate (8AP; 14.9%), and a 3.5-mm standard TPLO plate (6P; 6.7%). Among the included stifles, 214 (62.6%) fixation systems were classified as locking, and 128 (37.4%) were classified as nonlocking. The fixation system was predictive of complications. The 8P had the lowest odds ratio for complication among the 3 fixation systems. Odds of developing complications were higher with the 8AP fixation system than with the 8P fixation system. Locking fixation eliminated the association between weight and complication rate. CONCLUSION: Fixation of a TPLO with the 8AP increased the risk of complications compared with the 8P in this population of large dogs. CLINICAL SIGNIFICANCE: Locking fixation of TPLO with a 3.5-mm broad TPLO plate alone should be considered in large dogs because it may reduce complications.
