  Purpose

The purpose of this study is to compare the analgesic effectiveness of three techniques: the femoral nerve block, intraarticular infiltration or a combination of both in the control of pain in total knee arthroplasty (KA). The hypothesis to be tested in this study is that the performance multimodal postoperative pain KA combining two analgesic techniques to obtain better analgesia than when applied separately.

Primary Outcome Measures:
  • postoperative pain [ Time Frame: 48 hours postoperatively ] [ Designated as safety issue: No ]
    Is measured at the time of starting rehabilitation, postoperatively 48 hours using visual analog scale, numerical and categorical verbal pain scale at 12,24 and 48 hours


Estimated Enrollment: 156
Study Start Date: April 2011
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: femoral block Drug: ropivacaine
The lock is held before starting the operation, viewing with ultrasound and confirmed the femoral nerve with nerve stimulation at an intensity of 0.5 mA and a frequency of 2 Hz Pajunk 50mm needle, patellar flexion. It be administered 30ml of ropivacaine 0.75% (225mg)
Experimental: local infiltration + femoral nerve block
Combination of local infiltration with drugs and femoral nerve block
Drug: morphine ,ketorolac
ultrasound-assisted femoral nerve block is performed and leaks intraoperatively with a 100 ml solution containing: 5 mg of morphine to 0.1% (5ml) +30 mg of ketorolac (1 ml) +96 ml of 0.9% saline.
Active Comparator: several drugs local infiltration Drug: several drugs: morphine chloride,ropivacaine,epinephrine,ketorolac
This technique is performed intraoperatively with a 100 ml solution containing: 225 mg of ropivacaine 1% (22.5 ml) + 5 mg of morphine chloride 0.1% (5ml) + 30 mg of epinephrine 1:1000 (0.3 ml ) + ketorolac 30mg (1ml) +71 ml of 0.9% saline
Drug: ropivacaine,morphine chloride,epinephrine,ketorolac
This technique is performed intraoperatively with a 100 ml solution containing: 225 mg of ropivacaine 1% (22.5 ml) + 5 mg of morphine chloride 0.1% (5ml) + 30 mg of epinephrine 1:1000 (0.3 ml ) + ketorolac 30mg (1ml) +71 ml of 0.9% saline
