Single Shot Versus Continuous Adductor Canal Block in Patients Undergoing Total Knee Arthroplasty
- 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
Name Time Method postoperative pain scores by visual analogue score 48 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
Name Time Method the 30-Second Chair test 48 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 test 48 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
