The HOOS JR (Hip disability and Osteoarthritis Outcome Score for Joint Replacement) is a six-question survey that measures hip health in patients with hip osteoarthritis, especially before and after total hip replacement. Stephen Lyman, PhD, and colleagues (2016) at Hospital for Special Surgery developed the HOOS JR from the original 40-question HOOS (Nilsdotter, 2003). They kept only questions from the pain and daily-function sections, giving a single “hip health” score that patients can finish in a few minutes. CMS uses it in its required patient-reported outcome measure for elective hip replacement.

What it asks: Patients rate their hip over the past week on six items. Two are about pain: going up or down stairs, and walking on an uneven surface. Four are about daily function: rising from sitting, bending to the floor to pick something up, lying in bed (turning over or keeping the hip in position), and sitting. Each item uses the same five answers: None (0), Mild (1), Moderate (2), Severe (3), or Extreme (4).

How it’s scored: Scoring has two steps. First, add the six answers to get a raw score from 0 to 24, then convert it to an interval score using the table below. On the final scale, 0 represents total hip disability and 100 represents perfect hip health. For example, a raw score of 12 converts to 53, and a raw score of 6 converts to 70. The table isn’t a straight line, so you can’t get the result by simple division.

How results are used: The HOOS JR is usually given before surgery to set a baseline and again after recovery. The difference between the two interval scores shows how much the patient improved. For CMS reporting, an improvement of at least 22 points counts as a substantial clinical benefit.

HOOS, JR. Raw Score

A lower score represents better function.
The sum of the seven item responses, from 0 (no symptoms) to 24 (extreme symptoms).
The interval score above converts this raw total to a 0–100 scale.

Pertinent Positive: Extreme hip pain with bending to floor/pick up an object

Pertinent Positive: Extreme hip pain with lying in bed (turning over, maintaining hip position)

Pertinent Positive: Extreme hip pain with rising from sitting

HOOS, JR. Interval Score

Scoring

A Higher score represents better function.
The raw summed score is converted to an interval score from 0 to 100, where 0 represents total hip disability and 100 represents perfect knee health.

Interpretation

The HOOS, JR. interval score summarises hip pain and functional limitation in a single number from 0 to 100. A higher score means less hip difficulty; a lower score means more. The score is interpreted by your clinician, usually by comparing it with your earlier scores to track change over time.

Pertinent Positive: Extreme hip pain with sitting

Pertinent Positive: Extreme hip pain with going up or down stairs

Pertinent Positive: Extreme hip pain walking on an uneven surface
