Ultrasound Guıded Adductor Canal Block vs Perıcapsular Nerve Group Block in Knee Artroplasty

A linear ultrasound probe will be placed medial to the patella, the probe will be advanced to cephalad, and the superficial femoral artery will be visualized. The block site will be confirmed by injecting 5 ml of saline around the saphenous nerve in the subsartorial region under ultrasound guidance. Then, 30 ml of local anesthetic solution containing 0.25% bupivacaine (Marcain 0.5% AstraZeneca, England) will be administered.

The probe will be placed at the anterior superior level of spina iliaca, parallel to the inguinal ligament. The probe will be scanned gradually towards the caudal. After the anterior inferior of the spina iliaca is visible, the probe will be slightly turned medially until the hyperechoic shadow of the superior pubic ramus is visible. The psoas muscle tendon will be visualized above the superior pubic ramus, then 5 ml of saline will be injected under the psoas tendon and the block location will be confirmed. After that 30 ml of 0.25% bupivacaine will be administered.
