Subsartorial Saphenous Nerve Block (SSNB) Versus Femoral Nerve Block (FNB) in Primary Total Knee Arthroplasty (TKA) Combined With Infiltration Between Popliteal Artery and Capsule of the Knee (IPACK) - Where Are the Benefits?
Status: Recruiting
Location: See location...
Intervention Type: Other
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
The goal of this clinical trial is to compare two different types of nerve blocks in patients undergoing surgery for primary Total Knee Arthroplasty. The main question aim to answer is: \- is there a benefit in functional muscle power output of the leg? Participants will be randomized into either the intervention group or the control group and: * receive Subsartorial Saphenous Nerve Block (SSNB) + IPACK in intervention group (group 1) * receive Femoral Nerve Block (FNB) + IPACK in control group (group 2) Researchers will compare the 2 groups to see if there are differences in : * functional muscle power output of the leg? * muscle function, mobility, clinical and radiological results, ROM, pain control (NRS), opioid consumption, length of hospital stay, patient satisfaction, mobility, reduction of costs?

Subsartorial Nerve Block:~* 15ml bupivacaine 0.5% + clonidine 1mcg/kg for prolongation of the block effect~* anatomic landmarks: proximal adductor channel, intersection of the medial borders of the sartorius muscle and the adductor longus, guided by ultrasound control~* no patch to puncture site to not jeopardise the surgeon's blinding~* IPACK: 15ml bupivacaine 0.5% after completion of the femoral preparation
Active_comparator: Control group: FNB + IPACK (group 2)
Femoral Nerve Block:~* 15ml bupivacaine 0.5% + clonidine 1mcg/kg for prolongation of the block effect~* anatomic landmarks: lateral to the femoral artery,level of the femoral crease (proximal to the vascular outlet of the deep artery of the thigh), femoral nerve lies on the surface of the iliopsoas muscle and is covered by the fascia iliaca, guided by ultrasound control~* no patch to puncture site to not jeopardise the surgeon's blinding~* IPACK: 15ml bupivacaine 0.5% after completion of the femoral preparation
