Subsartorial Nerve Block and Femoral Nerve Block in Total Knee Arthroplasty

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?
