Plain-English summary
A group of 186 dogs that underwent tibial tuberosity advancement (TTA) surgery had a 5.3% chance of developing a surgical site infection (SSI) afterward. The study found that longer surgical and anesthesia times increased the risk of infection, with each additional minute raising the likelihood of SSI. Interestingly, giving antibiotics after surgery did not seem to lower the infection rate. Most dogs recovered well, with only a small number needing implant removal.

Abstract
OBJECTIVE: To examine perioperative factors affecting surgical site infection (SSI) rate following tibial tuberosity advancement (TTA). STUDY DESIGN: Retrospective case series. SAMPLE POPULATION: 224 stifles in 186 dogs. METHODS: Medical records of dogs that underwent TTA in a single institution were reviewed. Information on signalment, anaesthetic and surgical parameters, as well as occurrence of SSI was recorded. Dogs were followed for a minimum of three months postoperatively. The association between perioperative factors and SSI was assessed using Chi-squared tests and binary logistic regression. RESULTS: The prevalence of SSI was 5.3% (12/224 TTA). Surgical time (p = 0.02) and anaesthesia time (p = 0.03) were significantly associated with SSI. For every minute increase in surgical time and anaesthesia time, the likelihood of developing SSI increased by seven percent and four percent respectively. The use of postoperative antimicrobial therapy was not significantly associated with lower SSI (p = 0.719). Implants were removed in 1.3% of cases (3/224 TTA). CONCLUSIONS: The findings of this study suggest that increased surgical and anaesthesia times are significant risk factors for SSI in TTA, and that there is no evidence that postoperative prophylactic antimicrobial therapy is associated with SSI rate.
