^aThe KOOS JR is scored from 0 to 100, where 0 represents total knee disability and 100 represents perfect knee health.

^bAUROC between 0.7 and 0.8 is considered acceptable, and between 0.8 and 0.9 is considered excellent. AUROC = area under the receiver operating curve; PROMIS = Patient-Reported Outcome Measurement Information System; PCS = physical component score; MCS = mental component score.
