• 1 other identifier: TRUE KnORTH 2.0
• Study Type: interventional
• Target: N/A
• Locations: 1 country
• Sites: 1

Brief Summary

To assess feasibility of a a trial investigation postoperative patient-reported quality of recovery after total knee arthroplasty (TKA) with periarticular joint injection (PAI) ± single shot adductor canal block with or without adductor canal catheter infusion.

Conditions

Arthroplasty, Replacement, Knee

Outcome Measures

Primary Outcomes (1)

• Quality of Recovery-15 Survey scores

  Patient-reported Quality of Recovery scores, where higher scores indicate better quality of recovery

  Postoperative day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3

Secondary Outcomes (11)

• Quality of Recovery-15 Survey scores

  Postoperative days 10 and 42

• Brief Pain Inventory - Pain Interference scores

  Postoperative days 1, 2 and 3 in the morning

• Pain Numerical Rating Scale at rest

  Postoperative Day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3

• Pain Numerical Rating Scale with activity

  Postoperative Day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3 after physiotherapy

• Functional Recovery: Range of motion

  Postoperative Day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3 after physiotherapy
