A single email was sent to 4,233 patients who were at least 18 years old, not retired according to our electronic medical record, and scheduled for primary unilateral TJA. Note that 39 patients (not included in the 636) filled out a baseline survey but ended up cancelling their surgery and either did not reschedule or did not re-take the baseline survey before their surgery. An additional 8 patients cancelled their original surgery but ended up rescheduling and filling out the baseline survey again (only their final responses were counted). One participant enrolled but subsequently withdrew from the study (not included in the 636). Footnote 1: n=123 completed neither follow-up; n=80 completely only the 1-year follow-up; n=73 completed only the 6-month follow-up; and n=360 completed both follow-ups.
Footnote 2: at 1 year n=10 retired before returning to work and n=19 retired after returning to work; and at 6 months n=4 retired before returning to work and n=10 retired after returning to work.
