Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
All patients will be anesthetized with spinal anesthesia. Continuous infusion of ropivacaine with a catheter implemented to the adductor canal or next to the femoral nerve.
The observed goals: pain intensity, the beginning and quality of rehabilitation.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Before the beginning of operation, under ultrasound control, a catheter will be implemented to one of the chosen position: the adductor canal (the middle or lower third of thigh) or near the femoral nerve (below the inguinal ligament). The local anesthetic solution of 0.2 % ropivacaine will be started with an elastomeric pump (5 mL per hour, up to 72 hours) as soon as a catheter in the right position.
The pain will be measured with VAS (visual-analogue scale) 8, 24 and 48 hours after the end of operation, and at the discharge. At the same time, i.e.: 8, 24 and 48 hours from the end of surgery, the range of flexion and extension in the operated knee will be assessed. Moreover, the possibility of patient's sitting, standing up and walking will be noted.
All parameters will be reassessed before patients' discharge from the hospital. Each patient will receive paracetamol (1.0) and metamizol (1.0) intravenously (i.v.) q6h. 5 mg of morphine may be given as required, up to 2 dosages per day as a rescue medication.

continuous anesthesia of adductor canal
continuous anesthesia of adductor canal
After subarachnoid anesthesia, but before the beginning of surgery, a catheter will be implemented to the adductor canal and infusion of 5 mL/h of 0.2 % ropivacaine will be started.
Spinal anesthesia
Before the beginning of surgery all patients will be anesthetised with 0.5 % hyperbaric bupivacaine (Marcaine Heavy), 2.0 - 2.5 mL solution. Pencil point spinal needle will be used.
continuous anesthesia of femoral nerve
continuous anesthesia of femoral nerve
After subarachnoid anesthesia, but before the beginning of surgery, a catheter will be implemented next to the femoral nerve (below inguinal ligament) and infusion of 5 mL/h of 0.2 % ropivacaine will be started.
