HOS · Hip Outcome Score

28 items · 7 min · 0–100 per subscale · higher is better

1 Before you use it

What it is

Two subscales — a 19-item activities of daily living scale and a 9-item sport scale — built for a younger, more active hip population than HOOS.

When to reach for it

FAI, labral pathology and post-arthroscopy hips, particularly in athletes.

2 Giving it

Scoring

Report the two subscales separately as percentages of the maximum possible, with items marked not applicable excluded. Higher is better.

What it doesn’t measure

Groin-specific demand — use HAGOS. Strength, range or impingement testing.

3 Reading the score

Interpreting it

Interpret against baseline.

The sport subscale is where a young hip actually shows its problem — the ADL scale ceilings quickly in this population.

Is the change real?

MCID 7.9 points on the ADL subscale, 13.1 on Sports. Compare the change against this patient's own baseline as well as the figure. SourceMeasured in a hip arthroscopy cohort.

Student trap. Reporting only the ADL subscale on an athlete. They'll ceiling it and you'll have measured nothing.
