Outcome Measures

Primary Outcomes (1)

  • Mean Pain on Movement Score

    Mean pain on movement score was defined as the mean of the pain on movement score over Days 1 to 5 post-surgery. Pain experienced by participant during passive flexion through 90 degree and passive abduction through 30 degree at operated hip joint was evaluated on a scale of 0 to 10 where, 0= no pain and 10= worst possible pain.

    Every 12 hours from Day 1 to Day 5 post-surgery

Secondary Outcomes (6)

  • Mean Daily Pain Score

    Day 1 to Day 7, Day 8 to Day 14 post-surgery

  • Mean Daily Sleep Interference Score

    Day 1 to Day 5 post-surgery

  • Mean Anxiety Visual Analogue Scale (A-VAS)

    Day 0 to Day 5 post-surgery

  • Time to Mobilization After Surgery

    Day 1 to Day 5 post-surgery

  • Number of Participants With Rescue Medication Usage

    Day 0 to Day 6 post-surgery

You may qualify if:

  • The patient is undergoing a routine (i.e., expected to be uncomplicated) total primary or secondary hip replacement surgery performed under a standardized regimen of spinal anesthesia, and is expected to experience moderate to severe post-surgical pain in the absence of post-operative analgesia

You may not qualify if:

  • The patient is undergoing a revision to a previous hip replacement procedure, hip replacement procedure further to a road traffic accident with multiple injuries, or a procedure expected to last longer than 4 hours
  • The patient has a history of uncontrolled chronic disease or a concurrent clinically significant illness or medical condition, which in the Investigator's opinion, would contraindicate study participation or confound interpretation of the results
