Effects of Ultrasound-guided Adductor Canal Block Versus Femoral Nerve Block on Pain and Quadriceps Strength After Ambulatory Knee Arthroscopic Surgery

NCT05190120 Phase 4 COMPLETED Results posted

The purpose of this study is to compare the effects of a femoral nerve block vs. an adductor canal block on pain and quadriceps muscle strength for knee arthroscopy surgery.

Conditions

• Anterior Cruciate Ligament Tear
• Knee Meniscus Tear

Interventions

• Femoral Nerve Block
• Adductor Canal Nerve Block
• preoperative Femoral Nerve Block using 20ml of 0.5% ropivacaine
• Preoperative Adductor canal block with 0.75%% ropivacaine 13.3ml.

Primary outcomes

• Change in Quadriceps Strength Related to the Nerve Block — Baseline and 20 minutes after the block prior to surgery
  Quadriceps strength will be tested with a dynamometer before the nerve block and 20 minutes after the nerve block prior to surgery. The dynamometer measures the strength of the quadriceps muscles in the seated position while pushing against the device. We are trying to measure the effect of both femoral and adductor canal nerve blocks on quadriceps strength.
