Total Knee Arthroplasty With and Without Schedule II Opioids: A Randomized, Double-Blinded, Placebo-Controlled Trial.
Curēus 2024 March
INTRODUCTION: Orthopedic surgeons are the third highest prescribers of narcotics. Previous work demonstrated that surgeons prescribe three times the narcotics required, and most patients do not properly dispose of leftover medication following surgery. This has prompted the creation of multimodal pain regimens to reduce reliance on narcotics. It is unknown if these pathways can effectively eliminate opioids following total knee arthroplasty (TKA). Our purpose was to evaluate a multimodal regimen without schedule II narcotics following TKA, in a randomized, blinded fashion. We hypothesized that there would be no difference in pain scores between groups.
METHODS: A total of 43 narcotic-naïve patients participated in a randomized, double-blinded, placebo-controlled trial. Postoperative protocols were identical between cohorts, except for the study medication. The narcotic group received an encapsulated 5 mg oxycodone, whereas the control group received an encapsulated placebo. Perioperative outcomes were compared with routine statistical analysis.
RESULTS: Four patients withdrew early secondary to pain: three in the placebo group and one in the narcotic group (p=1.00). We found no difference in hospital length of stay (p=0.09) or pain scores at all time points between cohorts (all p>0.05). There was a higher proportion of patients using a narcotic in the opioid treatment arm at day 30 (40% vs. 21.4%, p=0.29) and day 60 (20% vs. 7.1%, p=0.32), although this was not statistically significant.
CONCLUSION: A multimodal regimen without schedule II narcotics demonstrates equivalent pain scores and may reduce the risk of long-term opioid dependence following TKA.
