What Is the HOOS JR? A Modern Metric for Hip Surgery Outcomes

Written by PatientIQ | Dec 8, 2025 4:00:00 PM

Tracking how patients feel after hip replacement surgery is key to understanding recovery. The Hip Disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS JR) captures this perspective in a focused, efficient format.

It’s one of several patient-reported outcome (PRO) measures used in orthopedics to assess symptoms, monitor progress, and meet reporting requirements. HOOS JR offers a standardized way to collect input directly from patients about their hip function following surgery.

What is HOOS JR?

The HOOS JR is a short-form PRO measure designed for individuals undergoing total hip arthroplasty. Developed from the longer HOOS (Hip Disability and Osteoarthritis Outcome Score) survey, it focuses on the aspects of hip function that matter most to patients during recovery while reducing the time required to complete.

The survey concentrates on symptoms and functional limitations that are common after hip replacement. HOOS JR is typically used to monitor progress over time, helping care teams evaluate outcomes using a consistent and validated tool.

Structure & Scoring

Questions:

HOOS JR includes 6 questions selected from the full HOOS survey. These questions focus on core aspects of hip function, such as pain during movement, difficulty with mobility, and overall joint stiffness.

Scale:

Patients respond using a 5-point Likert scale ranging from “None” to “Extreme,” based on the level of difficulty or discomfort they experience.

Scoring:

Responses are scored, transformed to a 0–100 scale, and averaged. Higher scores indicate better perceived hip function.

This condensed format reduces time to complete while still capturing meaningful information about post-surgical recovery.

Who Uses HOOS JR?

HOOS JR is used across orthopedic practices, hospitals, and health systems that perform total hip arthroplasty. It provides a structured way to track recovery and capture PROs after surgery.

Organizations participating in CMS programs, such as the Hospital Inpatient Quality Reporting program, may include HOOS JR to support reporting requirements. Medical device companies and registries also collect HOOS JR data to monitor post-operative outcomes across populations.

Its brief format makes it a practical option for both routine care and larger outcomes efforts.

Practical Use and Clinical Value

HOOS JR makes it easier to collect PROs around total hip arthroplasty. Its short format fits into routine workflows and reduces time spent on survey administration.

Clinicians use it to track changes in hip function, identify unexpected recovery patterns, and inform follow-up discussions. Quality and research teams use the data to evaluate outcomes across procedures, providers, or locations.

Reliability and Validity

The HOOS JR has been validated in hip arthroplasty populations and demonstrates strong reliability and internal consistency. It focuses on the items most relevant to hip replacement recovery, capturing pain and function efficiently without sacrificing measurement quality.

It has been evaluated in hip replacement populations and found to demonstrate strong internal consistency and correlation with established measures.

Collect HOOS JR Data Seamlessly with PatientIQ

Manual survey collection creates gaps and slows down reporting. PatientIQ automates the process, delivering HOOS JR at the right points in the care journey and capturing responses electronically.

Results flow directly into the EHR, giving teams instant access to outcome data they can use to monitor recovery, identify trends, and meet program requirements, without adding work for clinical staff.
