Objective[edit | edit source]

Hip Pain

The hip disability and osteoarthritis outcome score (HOOS) is a questionnaire intended to be used to assess patient’s opinions about their hip and associated problems and to evaluate their symptoms and functional limitations during a therapeutic process [1][2].

Other versions of the HOOS have been developed based on the original 40-question questionnaire, for example, the HOOS PS (five items), HOOS JR (six items) and the HOOS-12 (see below).[3]

The HOOS is an extension of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Knee Injury and Osteoarthritis Outcome Score (KOOS) [1].

Intended Population[edit | edit source]

HOOS, outcome measure for eg THR

This measuring instrument is recommended when there are symptoms of hip disability, with or without osteoarthritis (OA).
Hip osteoarthritis is a common, chronic musculoskeletal condition and a cause of pain, functional disability and reduced quality of life [4].

The HOOS is meant to be used over short and long-term intervals to assess changes over time or the effect of treatment (medication, physiotherapy, operations) [2].

Factors that should be considered when using the HOOS include age, sex, weight, geographic location, other chronic diseases, history of an inactive hip problem, contralateral hip disease, and active knee, ankle, or foot problems[5][6][7].

Implementation[edit | edit source]

The HOOS questionnaire is a patient-administered self-report questionnaire and takes 7 to 10 minutes to complete. It is designed to be self-explanatory and user-friendly[1]. The HOOS includes 40 items with five possible responses, graded from 0 to 4 (0 points = worst possible score; 100 points = best possible score). Standardized answer options are given in 5 Likert boxes with scores from 0 to 4 (no, mild, moderate, severe and extreme) to answer the questions. The HOOS has five subcategories:

  1. Pain (10 items with a total score of 40 points)
  2. Symptoms and stiffness (five items with a total score of 20)
  3. Activities of daily living (17 items with a total score of 68)
  4. Function in sports and recreational activities (four items with a total score of 16)
  5. Quality of life (four items with a total score of 16)

HOOS 12[edit | edit source]

The HOOS-12 is a 12-item measure derived from the original HOOS. HOOS-12 contains

  • 4 HOOS Pain items,
  • 4 HOOS Function (Activities of Daily Living and Sport/Recreation) items
  • 4 HOOS Quality of Life (QOL) items.

HOOS-12 is easier to complete than the original HOOS. As with the full-length HOOS survey, HOOS12 is intended to elicit people’s opinions about the difficulties they experience due to problems with their hips. It covers aspects of pain, functional limitations and hip-related quality of life.[8]

  1. The HOOS-12 is a reliable and valid alternative to HOOS in THR patients with moderate to severe OA and provided three domain-specific and summary hip impact scores with substantially reduced respondent burden.[9]
  2. HOOS-12 scale scores are modified so 0 is the worst possible and 100 is the best possible, similar to the method used to score the original HOOS scales[8]. A HOOS-12 calculator is available at https://orthopowertools.com/HOOS12.

Results[edit | edit source]

Once the patient has completed the questionnaire, each subscale is calculated as a standardized score, using the following formula:

  • 100 – [(patient's score of the subscale x 100)/(total score of the subscale)]

Each subscale will get a score of 0 to 100, with 0 indicating extreme symptoms and 100 indicating no symptoms. The subscales can be plotted as a HOOS profile, by connecting the mean scores for all 5 dimensions with a line[1][2].

[10]

Evidence[edit | edit source]

The HOOS has undergone psychometric testing with evaluating hip osteoarthritis assessment but needs further testing in different varieties of patients with other hip disabilities.

Overall, the HOOS is a well-regarded measure for the evaluation of patients following a total hip replacement. The time required to complete the survey aside, it is a solid patient-reported outcome measure to consider[11].

It is recommended to use the HOOS in conjunction with other outcome measures[12]. It is useful compared with the Nonarthritic Hip Score and the modified Harris hip score (MHHS) [13], and when used alongside the Patient-Specific Complaints Instrument, the Numeric Pain Rating Scale and the Six Minute Walk Test[14].
