Arm && Interventions

Group	Intervention	Description
Ultrasound guided subpectineal obturator nerve block	Subpectineal Injection	In supine position, the ultrasound probe will be placed on in inguinal region, 1-2 cm below to the inguinal crease to identiy the subpectineal area. Patients in this group will receive subpectineal obturator nerve block under ultrasound guidance.
Ultrasound guided interfascial obturator nerve block	Interfascial Injection	In supine position, ultrasound probe will be placed on inguinal region, 2-3 cm below to the inguinal crease. Patients in this group will receive interfascial obturator nerve block under ultrasound guidance.

Primary Outcome Measures

Name	Time	Method
Success rate of obturatr nerve block	Peroperative period	The success or fail of the obturator nerve block will be conformed using nerve stimulator. Detecting muscles twitch will br considered to be a fail.

Secondary Outcome Measures

Name	Time	Method
Procedure time	During the procedure	Block performance time will be recorded from the time the first ultrasound image is obtained until the procedure is completed
Sensory block	30 minutes after the intervention	Sensory block area will be evaluated by a pin prick at in the dermatomal areas related obturator nerve and branches.
Patient satisfaction	Peroperative period	Changes in overall satisfaction will be assessed using a 5 point Likert Scale ( 1-very dissatisfied, 2- dissatisfied, 3- neutral, 4-satisfied, 5 - very satisfied
Number of adductor muscle spazms	Intraoperative period	Number of adductor muscle spazms in each group will be noted during the intraoperative period.
