Abstract
The purpose of this study was to establish preoperative validity of the Patient-Reported
Outcomes Measurement Information System physical function computer adaptive test (PROMIS
PF-CT) with legacy patient-reported outcome measures (PROMs) for meniscal root tears
(MRTs). Our study included 51 patients (52 knees) with MRT. Patients completed PROMIS
PF-CT, Short Form 36 (SF-36 physical function, pain, general health, vitality, social
function, emotional well-being, role limitations due to physical health, and role
limitations due to emotional problems), Knee Injury and Osteoarthritis Outcome Score
(KOOS pain, symptoms, activities of daily living [ADLs], sports, and quality of life
[QOL]), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC pain,
stiffness, and function), EuroQol-5 dimensions (EQ-5D), and Knee Activity Scale questionnaires
at their preoperative visit. Correlations between the PROMs listed above were evaluated
along with floor and ceiling effects. Correlations were defined as weak (0.2–0.39),
moderate (0.4–0.59), strong (0.6–0.79), and very strong (0.8–1.0). Preoperative data
showed that PROMIS PF-CT has a strong correlation with SF-36 PF, KOOS-ADL, WOMAC-function,
and EQ-5D; and moderate correlation with KOOS-sport, KOOS-pain, KOOS-symptoms, KOOS-QOL,
WOMAC-pain, and WOMAC-stiffness. The Knee Activity Scale did not show any significant
correlation with PROMIS PF-CT (r = 0.12, p = 0.2080). Of all the PROMs administered, PROMIS PF-CT demonstrated no floor or ceiling
effects compared with 11.54% ceiling effect in KOOS-sports, and 5.77% floor effect
in KOOS-ADL. On average, patients answered fewer PROMIS PF-CT questions (4.15 ± 0.72).
PROMIS PF-CT is a valuable tool to assess preoperative patient-reported physical function
in patients that may undergo MRT repair. It correlates strongly with other well-established
PROMs. It also demonstrated no floor or ceiling effects and demonstrated a low test
burden in our sample of 52 knees. This is a level III, prognostic retrospective comparative
study.
