Postoperative analgesia in this group will be carried out by a single-shot bolus of 20 ml Ropivacaine 0.5% in the region of the middle third of the adductor canal.

Postoperative analgesia in this group will be carried out by continuous infusion of local anesthetics through a catheter installed to the femoral nerve in the area of the femoral triangle. Ropivacaine 0.2% solution will be used for postoperative analgesia. Local anesthetic infusion rate is 4 ml/h to 10 ml/h.
