Single Shot Versus Continuous Adductor Canal Block in Patients Undergoing Total Knee Arthroplasty

Not Applicable
Completed
Conditions
Rheumatism Knee
Registration Number
NCT04986878
Lead Sponsor
Aswan University Hospital
Brief Summary

Adductor canal block (ACB) has emerged as an option for postoperative regional analgesia in patients undergoing total knee arthroplasty (TKA).

Detailed Description

Various approaches to the performance of peripheral nerve blocks for postoperative pain control in patients undergoing TKA have been described in the literature. These approaches include lumbar plexus block, femoral nerve block (FNB), with or without a sciatic nerve block, and most recently the ACB. FNB is a commonly used modality for postoperative analgesia after TKA. It is considered by some as the gold standard or the cornerstone of postoperative analgesia after TKA. However, FNB reduces quadriceps muscle strength essential for mobilization and active contribution in any physical rehabilitation program. Quadriceps weakness places the patients at risk of falling. which may be detrimental to postoperative recovery. The ACB has recently emerged as an appealing alternative to FNB as it is predominately a sensory nerve block of a more distal branch of the femoral nerve ( the saphenous nerve).

Study & Design

Study Type
INTERVENTIONAL
Study Design
PARALLEL
Primary Outcome Measures
NameTimeMethod
postoperative pain scores by visual analogue score48 hours

visual analogue score is a straight, vertical 10-cm line with the bottom point representing "no pain" = (0cm) and the top point representing "the worst pain you could ever have" = (10 cm).

Secondary Outcome Measures
NameTimeMethod
the 30-Second Chair test48 hours

determines how many times a person can rise from a chair and sit down again in 30 seconds while keeping their arms crossed over their chest

six-minute walking test48 hours

calculates the distance that can be walked in 6 minutes

time to up and go test (minutes)48 hours

determines how long it takes a person to get out of a chair
