ART Score Calculator

Arthroplasty Risk Tool

Free · Designed for iPad

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). Key features •Reference ranges listed •Sex-specific Hgb guidance •Color-coded risk tiers •Simple score scale for easy interpretation •Metric/imperial height and weight inputs •Automatic BMI calculation based on height and weight entries vs. manual BMI entry •Copy/Share summary •Works offline; fast in clinic •No account necessary •Data stays on device unless you choose to share Disclaimer ART Score is a clinical decision support tool for licensed healthcare professionals. It does not diagnose or treat disease and does not replace clinician judgment, insurance authorization or payment, govenmental policy or regulation, or shared decision-making with the patient.
