Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Knee arthroplasty surgery numbers are increasing depending on joint deformities and cartilage degenerations. Severe postoperative pain may occur in these patients due to surgery and the placed prosthesis.

The aim of study is to compare the effectiveness of AKB and PENG block for postoperative analgesia management after knee arthroplasty.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Knee arthroplasty surgery numbers are increasing depending on joint deformities and cartilage degenerations. Severe postoperative pain may occur in these patients due to surgery and the placed prosthesis. Postoperative analgesia is important for early mobilization. So that, early movement of the joint is ensured and complications such as thromboembolism and infection are prevented. Various methods can be used for postoperative analgesia. One of these methods is epidural analgesia. However, it may not be applied due to the patient's refusal or the technical difficulties in the application. Another option is opioid agents. However; opioids have side effects such as nausea, vomiting, sedation, respiratory depression. Femoral nerve blockade can be done, but it is not preferred because it may prevent mobilization as a result of motor blockade.

Current regional anesthesia techniques used in knee surgery include selective blockade of the saphenous nerve in the adductor canal (adductor canal block-ACB) and pericapsular nerve group block (PENG). Adductor canal block; affects the vastus medialis branch of the saphenous nerve, one of the two largest sensory nerves from the femoral nerve to the knee, and the articular branches of the obturator nerve. Since the block is made in the distal thigh, the innervation of the quadriceps muscle is not affected, and therefore the motor power of this muscle is largely preserved. Another lower extremity peripheral regional blockade technique that is gaining importance today is PENG block. PENG, which is a musculofacial plane block made between the tendon of the psoas muscle and the ramus pubis, provides block of the femoral nerve, obturator nerve and accessory obturator nerve. In both block methods, pure sensory blockade provides analgesia without quadriceps muscle weakness, and this provides a significant advantage in terms of early mobilization.

The aim of this study is to compare these two analgesic methods in terms of effectiveness for postoperative analgesia management after knee arthroplasty. The primary outcome is to compare global recovery scores (QoR-15 scale), the secondary outcome is to compare postoperative pain scores (NRS), to evaluate postoperative opioid consumption, postoperative rescue analgesic (opioid) use, presence of motor blockade, postoperative first mobilization time, and side effects (allergic reaction, nausea, vomiting) associated with opioid use in this study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Adductor canal block

Adductor canal block will be performed at the end of the surgery. Patients will be administered tenoxicam (Tilcotil 20 mg flakon) 20 mg IV every 12 hours in the postoperative period. A patient controlled device prepared with 5 mg/ ml tramadol (100 mg-Contramal ® ampul) will be attached to all patients with a protocol included 10 mg bolus without infusion dose, 20 min lockout time and 4 hour limit. If the VAS score will be ≥ 4, 0,5 mg/kg-1 meperidine (Aldolan ampul 100 mg/2 ml) IV will be administered.

Group Type ACTIVE_COMPARATOR

Adductor canal block

Intervention Type DRUG

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.

PENG block

PENG Block will be performed at the end of the surgery. Patients will be administered tenoxicam (Tilcotil 20 mg flakon) 20 mg IV every 12 hours in the postoperative period. A patient controlled device prepared with 5 mg/ ml tramadol (100 mg-Contramal ® ampul) will be attached to all patients with a protocol included 10 mg bolus without infusion dose, 20 min lockout time and 4 hour limit. If the VAS score will be ≥ 4, 0,5 mg/kg-1 meperidine (Aldolan ampul 100 mg/2 ml) IV will be administered.

Group Type ACTIVE_COMPARATOR

PENG block

Intervention Type DRUG

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.
