Harris Hip Score Calculator
Determine the Harris Hip Score (HHS) to evaluate hip function and outcomes after arthroplasty.
Input Parameters
Enter details for calculation.
Harris Hip Score
Expert Tip
HHS ≤ 70 is considered poor. Scores of 80-89 indicate good function, and 90-100 represent excellent outcomes.
Calculation Methodology & Details
Formula
Standard orthopedic assessment measuring pain (max 44 pts) and function (max 47 pts).

ℹ️ About this Calculation
This orthopaedics and musculoskeletal clinical calculator evaluates joint replacement outcomes, osteoporotic fracture risk, spinal deformity severity, and physical mobility benchmarks based on AAOS clinical protocols.
Variable Glossary
Biomechanical Data
DXA T-score, Cobb angle degrees, gait velocity (m/s), dynamometer grip strength (kg), or functional survey items.
Functional Index
10-year major osteoporotic fracture probability (FRAX %), Oxford joint score (0-48), or spinal curvature classification.
How to Calculate Step-by-Step
Step 1
Input patient bone density BMD values, spinal radiograph degrees, or physical test performance numbers.
Step 2
Select patient age, gender, and secondary clinical risk factors (prior fracture history, steroid use).
Step 3
Review calculated joint function impairment tiers, sarcopenia risk categories, or fracture intervention thresholds.
