Dexamethasone in Total Knee and Total Hip Arthroplasty

November 21, 2017 updated by: University Health Network, Toronto

Does the Addition of Dexamethasone to a Local Infiltration Analgesia Mixture Improve Functional Outcomes Following Total Joint Arthroplasty?

This study will evaluate if the addition of dexamethasone to a local infiltration analgesia mixture will improve functional outcomes following total hip and knee arthroplasty.

Detailed Description

The addition of dexamethasone to an local infiltration analgesia (LIA) mixture for postoperative analgesia following total knee arthroplasty (TKA) has a limited evidence base. Although there is increasing support in the literature for its use in peripheral nerve blockade, there have only been a handful of studies assessing its applicability in periarticular LIA. Moreover, the evidence from peripheral nerve blocks suggests that one of the key benefits of dexamethasone is a prolongation of nerve blockade. Additionally, dexamethasone has been shown to prolong the local analgesic effect of bupivacaine microcapsules.

With respect to total hip arthroplasty (THA), there have only been two small studies that included corticosteroids in the LIA mixture; there was analgesic benefit and better early rehabilitation outcomes when compared to placebo. However, there is limited high-quality evidence for either THA or TKA demonstrating an improvement in functional outcomes when dexamethasone is used in an LIA mixture. This study will evaluate if the addition of dexamethasone to a local infiltration analgesia mixture will improve functional outcomes following total hip and knee arthroplasty.

Time Frame: 3 days - post operative
3 days - post operative

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Analgesic outcomes- pain
Time Frame: 3 days - post operative

Pain scores assessed with an 11 point verbal numeric rating scale (NRS) at the following time points:

  1. The post-anesthetic care unit (PACU)
  2. Postoperative day (POD) 1 at rest between 8-10 AM
  3. POD1 during physiotherapy
  4. POD 2 at rest between 8 -10 AM
  5. POD 2 during physiotherapy

g. POD 3 during physiotherapy if still in hospital
3 days - post operative
Analgesic outcomes- opiate consumption
Time Frame: 3 days - post operative
Cumulative systemic opioid consumption measured as oral morphine mg equivalents on POD 1, POD2, and, if still in hospital, POD 3, as well as the proportion of patients who required "rescue" intravenous patient controlled analgesia (IV PCA) anytime in the postoperative period
3 days - post operative
Analgesic outcomes- TUG test
Time Frame: 3 days - post operative
Timed Up and Go Test (TUG) on postoperative days 2 or 3
3 days - post operative
Analgesic outcomes- Drug side-effects
Time Frame: 3 days - post operative

Incidence of opioid-related side effects:
