SE and percent of patients associated with each point estimate score at intake. Abbreviations: FS score, FS score estimated by the knee CAT; Percent, percentage of patients measured; SE, SE of the estimate associated with each point estimate.

Functional staging of lower-extremity function.

Clinical example. The patient's responses are circled on the figure: lighter gray circles identify the responses at intake, and darker gray circles identify responses at discharge. Notation: 1, extreme difficulty or unable to perform activity; 2, quite a bit of difficulty; 3, moderate difficulty; 4, a little bit of difficulty; 5, no difficulty; the “:” is the threshold cut-score between contiguous responses per item. Abbreviation: FSCH, FS discharge–FS admission.
