Oxford Knee Score Calculator

Oxford Knee Score Calculator for Orthopedics. The total supports a discussion of symptoms and function. It does not determine surgery eligibility or prove radiographic severity.

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

How this calculator works

This page records a modern 0-48 total, with higher scores indicating a better reported knee outcome. The official guide distinguishes this from the legacy 12-60 scale: https://innovation.ox.ac.uk/wp-content/uploads/2016/05/OKS-scoring-guide_2016-01-15.pdf.

When to use this calculator

Check version consistency before comparing clinic visits or surgical outcomes. A finalized fractional value is accepted when produced by the official missing-response workflow; this page does not perform that workflow.

Inputs used

  • Final modern Oxford Knee Score on the 0-48 scale
  • Version and any authorized missing-response handling

Clinical interpretation

The total supports a discussion of symptoms and function. It does not determine surgery eligibility or prove radiographic severity.

Worked example

A legacy score of 44 converts to modern 60 - 44 = 16. Entering 44 directly would reverse the impression of outcome. If comparable modern scores change from 16 to 28, the difference is 12 points; this page does not claim a universal clinically important change.

Limitations and safety notes

The instrument is licensed. No questionnaire, response options or missing-item algorithm is reproduced. Permission to use an instrument and interpretation of an already obtained score are distinct issues; this review grants no rights.

Frequently asked questions

Why is 32.5 accepted?

A finalized score can be fractional after authorized missing-response handling. Confirm its provenance instead of rounding it to fit an integer field.
