Efficacy of Multimodal Peri- and Intraarticular Drug Injections in Total Knee Arthroplasty

Phase 4
Completed
Conditions
Osteoarthritis of the Knee
Interventions
Registration Number
NCT00562627
Lead Sponsor
Asker & Baerum Hospital
Brief Summary

Total knee arthroplasty (TKA) is associated with moderate to severe postoperative pain, causing patient discomfort, mobilisation and hospital discharge.

The aim of this study is to:

1. Compare analgetic efficacy of to types of local infiltration analgesia in total knee arthroplasty.

2. Compare analgetic efficacy of local infiltration analgesia with continuous epidural analgesia.

Detailed Description

Total knee arthroplasty (TKA) is increasingly common in the treatment of knee osteoarthritis. TKA is associated with moderate to severe postoperative pain, causing patient discomfort, mobilisation and hospital discharge.

Continuous epidural analgesia is often used for controlling pain after TKA. Recent studies describe a new method for pain control after total knee arthroplasty which consists of local infiltration with local anesthetics and adrenaline. This infiltrations can be combined with ketorolac and/or morphine. The aim of this study is to:

1. Compare analgetic efficacy of to types of local infiltration analgesia in total knee arthroplasty.

2. Compare analgetic efficacy of local infiltration analgesia with continuous epidural analgesia.

Primary Outcome Measures
NameTimeMethod
Pain at Rest (VAS)48 hours postoperative

VAS (pain at rest) 0-100 mm. VAS 0 mm means no pain and VAS 100 mm means maximal pain.

Secondary Outcome Measures
NameTimeMethod
Opioid Use48 hours postoperative

Morphine used by patient controlled analgesia. Amount of used morphine during the first 48 hours after surgery were documented in the CRF by the pain nurses.

Time to Readiness for Dischargeup to 10 days postoperative

Each postoperative day, discharge readiness was assessed by an orthopaedic surgeon, a pain nurse, a ward nurse, and a physiotherapist according to the following criteria: no evidence for surgical complications, VAS pain at rest ≤30 mm which is controlled by oral analgesics, ability to eat and drink, ability to walk with elbow crutches, and ability to climb ≥8 stairs.
