What is a good Harris Hip Score?

Scores of 90–100 are Excellent, 80–89 are Good, 70–79 are Fair, and below 70 are Poor. Most successful total hip replacements achieve scores of 80 or higher at one year post-operatively.

How is the Harris Hip Score calculated?

The HHS sums four domain scores: Pain (0–44), Function (0–47, comprising Gait 0–33 and Activities 0–14), Deformity (0 or 4), and Range of Motion (0–5). The maximum total is 100 points.

Who developed the Harris Hip Score?

Dr. William H. Harris introduced the score in 1969 specifically to measure outcomes after hip arthroplasty. It remains the dominant hip-specific outcome tool in orthopedic literature despite newer alternatives.

Is the Harris Hip Score used for hip fractures too?

Yes. Although originally designed for arthroplasty outcomes, the HHS is routinely applied after hip fracture fixation, femoral osteotomy, and other hip disorders to provide a standardized functional benchmark.

What is a minimal clinically important difference (MCID) for the HHS?

Published studies report the MCID for the HHS at approximately 17–20 points. A change smaller than this threshold may not represent a meaningful functional improvement from the patient's perspective.

Does this tool replace a physician evaluation?

No. The HHS is a clinical assessment tool and results should be interpreted by a qualified orthopedic surgeon or physical therapist in the context of imaging, physical examination, and the patient's full history.

Summary

Score hip pain, function, deformity, and range of motion to calculate the Harris Hip Score and outcome grade.

How it works

Select the pain level that best describes the patient's current hip pain (up to 44 points).
Answer gait questions covering limp, support required, and walking distance (up to 33 points).
Answer functional activity questions about stairs, shoes/socks, sitting, and public transport (up to 14 points).
Indicate whether deformity criteria are absent (4 bonus points if all four are absent).
Enter range-of-motion arcs for flexion, abduction, adduction, internal rotation, and external rotation; the tool sums them and maps to the ROM score (up to 5 points).
The tool adds all four domain scores and displays the total HHS with an outcome classification.

Use cases

Assess hip function before and after total hip arthroplasty.
Track recovery progress at follow-up visits after hip replacement surgery.
Document pre-operative baseline function for surgical planning.
Compare outcome scores across treatment groups in clinical research.
Evaluate outcomes after hip fracture fixation or femoral head procedures.
Provide objective functional data for insurance authorization or occupational assessments.
Screen candidates for revision hip surgery by identifying poor functional scores.
Monitor rehabilitation milestones and set goal-based therapy targets.
