Summary
The Patient-Reported Outcomes Measurement Information System physical function computer adaptive test (PROMIS PF-CT) accurately assesses preoperative physical function for meniscal root tear patients. It shows strong correlations with other measures and no floor or ceiling effects.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Health Outcomes Research
Background:
- Meniscal root tears (MRTs) significantly impact knee function and patient quality of life.
- Accurate preoperative assessment of physical function is crucial for surgical planning and patient expectations.
- Legacy patient-reported outcome measures (PROMs) exist, but newer, more efficient tools require validation.
Purpose of the Study:
- To establish the preoperative validity of the Patient-Reported Outcomes Measurement Information System physical function computer adaptive test (PROMIS PF-CT) against established PROMs in patients with MRTs.
- To evaluate the correlation and psychometric properties of PROMIS PF-CT compared to multiple legacy PROMs.
Main Methods:
- A cohort of 51 patients (52 knees) with MRTs completed PROMIS PF-CT along with SF-36, KOOS, WOMAC, EQ-5D, and Knee Activity Scale questionnaires preoperatively.
- Correlations between PROMIS PF-CT and other PROMs were analyzed using established thresholds (weak, moderate, strong, very strong).
- Floor and ceiling effects, as well as test burden (number of questions answered), were assessed for PROMIS PF-CT.
Main Results:
- PROMIS PF-CT demonstrated strong correlations with SF-36 PF, KOOS-ADL, WOMAC-function, and EQ-5D.
- Moderate correlations were found with KOOS-sport, KOOS-pain, KOOS-symptoms, KOOS-QOL, WOMAC-pain, and WOMAC-stiffness.
- PROMIS PF-CT showed no floor or ceiling effects and required fewer questions (average 4.15) compared to other PROMs.
Conclusions:
- PROMIS PF-CT is a valid and reliable tool for assessing preoperative physical function in patients with MRTs.
- Its strong correlation with established PROMs, lack of floor/ceiling effects, and low test burden make it a valuable instrument.
- PROMIS PF-CT can aid in preoperative decision-making and outcome prediction for MRT repair.
