ART Score Calculator

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).
