NCT04432012

Brief Summary

We are going to evaluate the difference between perioperative intravenous steroid supplementation, perioperative periarticular steroid supplementation, and standard anaesthesia protocols. We'll evaluate the outcome of patients with knee osteoarthritis who are undergoing Total Knee Arthroplasty to understand which of the three treatments give more benefits to the patient.

Outcome Measures

Primary Outcomes (1)

  • Mean daily pain at rest during the first 3 days on a 0-10 numeric rating scale

    Mean daily pain at rest during the first 3 days reported on a 0-10 numeric rating scale (NRS) by the patients. The 0-10 NRS consists in a single 11-point numeric scale, with 0 indicating no pain and 10 reflecting the worst possible pain.

    3 days after surgery

Secondary Outcomes (16)

  • Post-operative knee pain during the first 6 weeks after surgery on a 0-10 numeric rating scale

    6 weeks after surgery

  • Post-operative knee pain during the first 10 years after surgery

    10 years

  • Post-operative function during the first 6 weeks after surgery

  • Post-operative knee function during the first 10 years after surgery
