What it measures:

The Hip Disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS, JR) is a patient-reported survey measuring overall hip health for individuals post total hip replacement (THR) by evaluating pain, function, and activities of daily living.(1,2)

This survey was developed at the Hospital for Special Surgery by Stephen Lyman, PhD, as a relevant short version of the HOOS for a specific population.(2)

Conditions & Test Variations Included in this Summary:

This summary contains information on the use of HOOS, JR in patients or clients following hip replacement surgery.

Variation/revision: HOOS, JR was the basis for development of HOOSglobal, a patient-reported outcomes measure used with patients undergoing periacetabular osteotomy (PAO), and may be used across hip-related subspecialties. HOOSglobal will not be further reviewed here.(3)

Target Population:

HOOS, JR is administered to patients with a hip joint replacement. HOOS, JR is a 6-question survey that assesses how the patient views their hip, and how well the patient is able to perform functional activities.(2)

Taskforce Recommendations:

  • American Academy of Hip and Knee Surgeon Symposium recommends HOOS, JR as an efficient outcomes assessment for total hip replacement, as it meets the Centers for Medicaid and Medicare requirements.(1)
  • American Academy of Orthopedic Surgeons recommend HOOS, JR for patients with hip osteoarthritis.(3)
  • Clinical Orthopaedics and Related Research on Value-Based Healthcare suggest using short-form instruments, such as HOOS, JR, at more frequent intervals than longer instruments.(9)
  • American Association of Hip and Knee Surgeons and Technical Expert Panel, consisting of representatives from American Association of Orthopaedic Surgeons, Hip Society, Knee Society, American Joint Replacement Registry, Centers for Medicare and Medicaid Services, Yale New Haven Health Services Corporation and the Center for Outcomes Research and Evaluation, National Committee for Quality Assurance, Mathematica, CECity, and Blue Cross Blue Shield Association suggest that HOOS, JR should be used with patients with specific diseases.(10)


Clinical Insights

HOOS JR is an efficient and responsive outcome measure with only 6 questions that provides meaningful data for older patients who have undergone hip arthroplasty, but this instrument is likely not appropriate for use with younger, more active hip patients.(3)

HOOS, JR requires a fifth-grade reading level meeting the American Medical Association recommendation that PROMs be written at or below a sixth-grade level.(11)
