Abstract
This is a retrospective study. Prior studies have characterized the deleterious effects
of narcotic use in patients undergoing primary total knee arthroplasty (TKA). While
there is an increasing revision arthroplasty burden, data on the effect of narcotic
use in the revision surgery setting remain limited. Our aim was to characterize the
effect of active narcotic use at the time of revision TKA on patient-reported outcome
measures (PROMs). A total of 330 consecutive patients who underwent revision TKA and
completed both pre- and postoperative PROMs was identified. Due to differences in
baseline characteristics, 99 opioid users were matched to 198 nonusers using the nearest-neighbor
propensity score matching. Pre- and postoperative knee disability and osteoarthritis
outcome score physical function (KOOS-PS), patient reported outcomes measurement information
system short form (PROMIS SF) physical, PROMIS SF mental, and physical SF 10A scores
were evaluated. Opioid use was identified by the medication reconciliation on the
day of surgery. Propensity score–matched opioid users had significantly lower preoperative
PROMs than the nonuser for KOOS-PS (45.2 vs. 53.8, p < 0.01), PROMIS SF physical (37.2 vs. 42.5, p < 0.01), PROMIS SF mental (44.2 vs. 51.3, p < 0.01), and physical SF 10A (34.1 vs. 36.8, p < 0.01). Postoperatively, opioid-users demonstrated significantly lower scores across
all PROMs: KOOS-PS (59.2 vs. 67.2, p < 0.001), PROMIS SF physical (43.2 vs. 52.4, p < 0.001), PROMIS SF mental (47.5 vs. 58.9, p < 0.001), and physical SF 10A (40.5 vs. 49.4, p < 0.001). Propensity score–matched opioid-users demonstrated a significantly smaller
absolute increase in scores for PROMIS SF Physical (p = 0.03) and Physical SF 10A (p < 0.01), as well as an increased hospital length of stay (p = 0.04). Patients who are actively taking opioids at the time of revision TKA report
significantly lower preoperative and postoperative outcome scores. These patients
are more likely to have longer hospital stays. The apparent negative effect on patient
reported outcomes after revision TKA provides clinically useful data for surgeons
in engaging patients in a preoperative counseling regarding narcotic use prior to
revision TKA to optimize outcomes.
