Threshold Values for Success After Hip Arthroscopy Using the Patient-Reported Outcomes Measurement Information System...

Area of Science:

• Orthopedics
• Rehabilitation Medicine
• Health Outcomes

Background:

• Patient-reported outcome measures (PROMs) are crucial for assessing functional improvement after surgery.
• Minimum Clinically Important Difference (MCID) and Patient Acceptable Symptomatic State (PASS) provide thresholds for meaningful recovery.
• Hip arthroscopy for femoroacetabular impingement (FAI) requires validated outcome measures.

Purpose of the Study:

• To establish PASS and MCID values for hip arthroscopy in FAI patients.
• To utilize the Patient-Reported Outcomes Measurement Information System (PROMIS) for outcome assessment.
• To identify factors influencing achievement of MCID and PASS.

Main Methods:

• A cohort study of 113 patients undergoing primary hip arthroscopy for FAI.
• PROMIS surveys for physical function (PF) and pain interference (PI) were administered preoperatively and at 1-year follow-up.
• Anchor-based methods and receiver operator curves determined MCID and PASS thresholds.

Main Results:

• MCID values were 5.1 (PF) and 10.9 (PI); PASS thresholds were 51.8 (PF) and 51.9 (PI).
• 83% of patients achieved MCID for PF; 58% achieved PASS for PF.
• Younger and athletic patients were more likely to achieve PASS (P=.003).

Conclusions:

• The PROMIS survey is effective for evaluating outcomes after hip arthroscopy for FAI.
• Established MCID and PASS values offer clinically meaningful benchmarks for patient recovery.
• These thresholds aid in surgical decision-making and patient expectation management.
