Overview
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).

Outcomes
Primary Outcomes
postoperative pain scores by visual analogue score
Time Frame: 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 Outcomes
- the 30-Second Chair test(48 hours)
- six-minute walking test(48 hours)
- time to up and go test (minutes)(48 hours)
