Outcome Measures

Primary Outcomes (1)

  • The average daily morphine equivalent dose consumption at 2 weeks post-surgery.

    2-week follow-up period from surgery

Secondary Outcomes (6)

  • Post-surgical opioid use during hospitalization and following discharge at 1 and 4 weeks post-surgery.

    1 and 4 weeks post-surgery

  • Knee pain severity assessed on a 10 cm visual analogue scale (VAS)

    At intervals over the 4-week follow-up period

  • The measurement of knee joint circumference

    Measurement performed preoperatively, on the first or second postoperative day, at the discharge dressing change, and at the 4 week follow-up visit

  • Range of motion of the knee joint, assessed using the knee flexion technique

    Assessed preoperatively, on the first or second postoperative day, at the discharge dressing change (unless discharged within 2 days), and at the 4 week follow-up visit

  • OA-related medication use including analgesics, anti-inflammatories, and other non-opioids

    4 weeks post-surgery

  • +1 more secondary outcomes
