Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	onset of spinal anaesthesia	seventy participants undergoing elective total knee arthroplasty under spinal anesthesia half of them took placebo and the other half took 150 mg pregabalin two hours before the procedure and calculate the time from the base line to the onset of anesthesia.; Our primary outcome is to assess the onset of spinal anesthesia.; to detect the onset of spinal anaesthesia	three months
Secondary	recovery time	Recovery time from the sensory blockade (2-dermatome regression of anesthesia from the maximum level).	three months
Secondary	motor block duration	the time for return to Bromag 2 (the patient is able to move knees and ankles).	three months
Secondary	postoperative analgesia	• Postoperative pain will be assessed by the patient using the visual analog scale in the first 24 hour(VAS, 0=no pain; 10=worst possible pain) every 2 hours up to 24 hours after the operation.	three months.
