Design outcomes

Primary

Measure	Time frame
1. The possibility of single injection site sciatic and femoral nerve blocks: 1.1. The possibility to perform sciatic nerve block from supratrochanteric area along mid-axillary line was assessed once at the moment of performing the block and was defined as possibility of eliciting motor response (plantar flexion) on neurostimulation with following neurostimulator settings: current 0.4 mA, impulse duration 0.3 ms and impulse frequency 2 Hz 1.2. The possibility to perform femoral nerve block from the same point also was assessed once at the moment of performing the block and was defined as possibility of eliciting motor response (patellar twitches) on neurostimulation with the same settings	—

Secondary

Measure	Time frame
1. Skin to nerve distances assessed once at the moment of performing the blocks using insulated needles with centimeter markings (Stimuplex A, 21G, 150 mm, B.Braun, Melsungen, Germany). The depth of needle insertion equaled to skin-to-corresponding nerve distance. 2. Pain intensity assessed according to Numeric Rating Scale (NRS, 0-10 points) during the first postoperative day at 1, 3, 6, 12 and 24 postoperative hours	—
