Interventions

Group I: control groupPROCEDURE

Group I: 30 Patients will receive the standard spinal anesthesia 12.5 mg (2.5 ml) of 0.5% hyperbaric bupivacaine with 25 µg of fentanyl (0.5 ml), with no intervention as a control group.

Group II: Ultrasound Guided Femoral Nerve BlockPROCEDURE

Group II: 30 Patients will receive the standard spinal anesthesia 12.5 mg (2.5 ml) of 0.5% hyperbaric bupivacaine with 25 µg of fentanyl (0.5 ml), then US guided FNB will be performed at the end of surgery, with 20 ml of 0.25% bupivacaine with 5 ml of magnesium sulfate 10% solution (500 mg) with total volume of 25 ml.
