Harris Hip Score Calculator

Harris Hip Score Calculator for Orthopedics. Higher totals generally reflect better measured hip status. The original instrument and modified versions are not interchangeable, even when both use a scale ending at 100. This page does not assign surgical eligibility or promise an outcome.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

This page records an externally completed original Harris total. It does not reproduce or rescore the questionnaire. The previous partial deformity scoring and simplified motion worksheet are removed rather than represented as the original examination method.

When to use this calculator

Document an already completed hip assessment when following outcomes over time. Confirm the instrument version, assessed side and visit date before comparing totals. An authorized assessment workflow must supply the total.

Inputs used

  • A completed original Harris Hip Score on its 0-100 scale, including the examination domains; do not substitute a modified score.

Clinical interpretation

Higher totals generally reflect better measured hip status. The original instrument and modified versions are not interchangeable, even when both use a scale ending at 100. This page does not assign surgical eligibility or promise an outcome.

Worked example

An externally finalized original total of 82.5 is recorded as 82.5 out of 100. A later original total of 88 is 5.5 points higher. That subtraction alone does not establish a clinically important improvement.

Limitations and safety notes

This is deliberately a total-entry tool, not a full Harris examination. It cannot detect mis-scoring upstream, recover missing motion measurements or confirm questionnaire permissions. Outcome-study findings are not independent validation of this software.

  • Prefer original validation studies for scoring systems and prediction tools.
  • Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
  • Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
