Brief Summary
The goal of this prospective, randomized study is to compare the outcomes of two cohorts of patients undergoing primary Total Knee Arthroplasty (TKA) and to determine whether a single dose of methadone administered preoperatively is effective at reducing postoperative opioid usage and postoperative pain versus a control group of patients receiving standard intraoperative opioids only for primary TKA. The main questions it aims to answer are:
- What is the efficacy of a single preoperative dose of methadone in reducing opioid consumption and postoperative pain in primary total knee arthroplasty?
- Will the study results demonstrate the effectiveness and safety of a single preoperative dose of methadone (10 mg) in primary total knee arthroplasty in reducing postoperative opioid usage while maintaining a similar or better level of pain control when compared to a standard pain control regimen? Researchers will compare Methadone to a standard pain control regimen (Oxycodone) to see if Methadone is equivalent or more effective at reducing opioid consumption and postoperative pain in primary total knee arthroplasty Participants will:
- be randomized into one of two groups
- undergo a primary TKA
- complete a tracking sheet documenting daily pain medicine usage and VAS pain level for the first 14 days following the TKA
- return to office at 2 weeks and 6 weeks postop for follow-up
- complete additional questionnaires at 2 weeks and 6 weeks postop

Outcome Measures
Primary Outcomes (3)
Daily Opioid Use
Daily Opioid Use as measured in MME recorded daily for the first two weeks following TKA
2 weeks
Total opioid usage over two weeks
total daily opioid usage (as measured in MME) during the first 14 days following TKA
2 weeks
Visual Analogue Scale pain score
Visual Analogue Scale knee pain score (minimum value: 0, maximum value: 10). Higher scores equate to a worse outcome (a score of zero = pain free).
