ART Score (Arthroplasty Risk Tool) helps clinicians bring objectivity and simplicity to preoperative risk assessment for Total Joint Arthroplasty. Instead of relying on single-variable “hard stops,” ART Score combines eight modifiable variables into a 0–100 score with four tiers (Low / Medium / High / Very High) to support shared decision-making, set attainable targets, and document progress before surgery. Using evidence-based criteria, it will help prevent limitation of access by third party payers. What it measures (8 variables): •Fructosamine •Hemoglobin (sex-specific) •Total lymphocyte count •Transferrin •Body mass index (BMI) •Prealbumin •Vitamin D •Smoking status Why it matters Objective & actionable: Focuses on modifiable risk factors rather than fixed cutoffs. Consistent: Standardizes preop assessment across surgeons and clinics. Patient-centered: Turns optimization into clear targets patients can work toward. Documentable: Provides a summary for the chart, referrals, insurers, and patient counseling. Designed for arthroplasty, potential for broader application. Built for total joint arthroplasty, with a path to adapt and validate for other surgical procedures where infection or wound complications are significant (e.g., spine, bariatric, vascular, plastic surgery).
