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.

Detailed description

Knee osteoarthritis (KOA) is a leading cause of chronic knee pain and disability, with a lifetime prevalence of 45%. Treatment for symptomatic KOA includes physical therapy, oral anti-inflammatory medications and intra-articular steroid injections, with total knee arthroplasty (TKA) (or knee replacement) as the definitive treatment. Acute postoperative pain is common after TKA, leading to increased opioid consumption and increased hospital length of stay. Pain control following TKA has been investigated with interventions such as intrathecal morphine, nerve blocks, and periarticular joint injection (PAI). PAI and adductor canal block are well-established techniques used both in combination or in isolation in the management of postoperative pain for patients undergoing TKA. The aim of this study is to assess postoperative patient-reported quality of recovery after TKA with PAI and single shot adductor canal block with or without adductor canal catheter infusion.

Design outcomes

Primary

MeasureTime frameDescription
Quality of Recovery-15 Survey scoresPostoperative day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3Patient-reported Quality of Recovery scores, where higher scores indicate better quality of recovery

Secondary

MeasureTime frameDescription
Quality of Recovery-15 Survey scoresPostoperative days 10 and 42Patient-reported Quality of Recovery scores, where higher scores indicate better quality of recovery
Brief Pain Inventory - Pain Interference scoresPostoperative days 1, 2 and 3 in the morningOn a scale of 0-10, where 0=Does not interfere and 10=Completely interferes, Patients will rate how much their pain interferes with: General activity, Mood, Walking ability, Normal work including housework, Relations with other people, Sleep, and Enjoyment of life
Pain Numerical Rating Scale at restPostoperative Day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3Patient-reported pain measured on an 11-point scale from 0 \[no pain\] to 10 \[worst pain imaginable\]
Pain Numerical Rating Scale with activityPostoperative Day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3 after physiotherapyPatient-reported pain measured on an 11-point scale from 0 \[no pain\] to 10 \[worst pain imaginable\]
Functional Recovery: Range of motionPostoperative Day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3 after physiotherapyFlexion and Extension range of motion measured in degrees
Functional Recovery: Time to reach discharge criteriaPostoperative Day 0 (2 hours postoperatively), and morning of postoperative days 1, 2 and 3 after physiotherapyPhysiotherapist to assess when patient meets discharge criteria (measured in half days)
Functional Recovery: Timed Up and Go testPostoperative day 42Time it takes for patient to stand up from sitting in a chair, walk 3 meters, then turn and walk back to chair and sit down, measured in seconds
Frequency of opioid-related side effects (vomiting and nausea)Up to 3 daysNumber of vomiting events or complaints of nausea noted in nursing notes
Narcotic consumption in hospitalUp to 3 daystotal amount and route of administration collected from routine and PRN opioid use in PACU and on surgical floor - measured in mg of oral morphine equivalence
Narcotic consumption at homePostoperative day 42Post-discharge opioid consumption will be tracked with pill count on POD 1 or 2, 3 POD10 (± 2 days), and POD42 (± 2 days); on POD 42 - patient to show study nurse how many pills remain to ensure reporting accuracy
ComplicationsPostoperative days 10 and 42i. return to hospital once discharged for non-analgesic reasons ii. require more pain medications outside of prescription given
