Background/Objectives: Surgical site infections (SSIs) are serious complications in orthopedic implant-associated procedures, increasing morbidity, mortality, and hospital costs. The purpose of this study was to evaluate the impact of a structured infection prevention and control (IPC) service on SSI incidence and cost savings across hip arthroplasty (HA), knee arthroplasty (KA), and open reduction and internal fixation (ORIF). Methods: A retrospective analysis included 6930 patients treated between 2019 and 2024, divided into pre-intervention (2019–2022) and post-intervention (2023–2024) cohorts. Preventive methods (PMs) comprised enhanced antibiotic prophylaxis, Staphylococcus aureus screening, chlorhexidine bathing, intraoperative audits, and behavioral interventions. Economic evaluation used literature-based costs, standardized to 2024 US dollars (USD 2024), with sensitivity analyses performed. Results: SSI incidence decreased from 5.6% to 1.1% overall (p < 0.001), with consistent reductions across procedures: ORIF (5.2%→1.0%), HA (9.2%→2.4%), and KA (4.8%→1.2%). In 2023, approximately 31 SSIs and one infection-related death were prevented, avoiding 308 hospital days. Cost savings ranged from USD 209,188 to USD 376,898, with cost saving confirmed in 93% of simulations. Conclusions: Comprehensive infection-prevention protocols, delivered through a structured IPC service, significantly reduced SSIs and generated substantial cost savings. These findings support wider use of these PMs in orthopedic surgery.
