Eligibility

Inclusion Criteria:

• 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

Exclusion Criteria:

• 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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	Mean Daily Pain Score	Mean daily pain score was defined as the mean of daily pain score over Days 1 to 7 and Days 8 to 14 post-surgery. Daily Pain Rating Scale (DPRS): participant rated 11-point Likert scale ranging from 0 (no pain) to 10 (worst possible pain) during past 24-hour period. Higher score indicates greater level of pain.	Day 1 to Day 7, Day 8 to Day 14 post-surgery
Secondary	Mean Daily Sleep Interference Score	Mean daily sleep interference score was defined as the mean of daily sleep interference numeric rating scale (NRS) score over Days 1 to 5 post-surgery. Daily Sleep Interference Scale (DSIS): participant rated pain during past 24-hour period on NRS ranging from 0 (pain does not interfere with sleep) to 10 (pain completely interferes with sleep). Higher score indicates a greater level of sleep disturbance. Self-assessment performed daily on awakening prior to taking study medication.	Day 1 to Day 5 post-surgery
Secondary	Mean Anxiety Visual Analogue Scale (A-VAS)	Mean anxiety visual analogue scale (VAS) was defined as the mean of VAS score on the day of surgery and over Days 1 to 5 post-surgery. Participants measured their degree of anxiety over past 24 hours on a VAS of 0 to 100, where 0 = not at all anxious to 100 = extremely anxious.	Day 0 to Day 5 post-surgery
Secondary	Time to Mobilization After Surgery	Participant was encouraged each day (from Day 3) to attempt walking depending upon the degree of pain on standing. The first day on which the participant was able to walk for 5 steps was the day of mobilization. Median time to mobilization (in hours) was calculated till the day of mobilization.	Day 1 to Day 5 post-surgery
Secondary	Number of Participants With Rescue Medication Usage	Rescue medications were used for participants with moderate or severe resting pain. Fentanyl injection (25 microgram [mcg] intravenous bolus to a maximum dose of 3 milliliter/day), paracetamol tablet (15 milligram/kilogram orally to a maximum dose of 45 milligram/kilogram/day) were used as rescue medications.	Day 0 to Day 6 post-surgery
Secondary	Number of Participants With Neuropathic Pain	ID Pain questionnaire was used to assess neuropathic pain. 6 items questionnaire, did pain feel like: (1)pins and needles (2)hot/burning (3)numb (4)electrical shocks (5)is pain made worse with touch of clothing or bed sheets (6)is pain limited to your joints. "Yes" response to questions 1-5 were scored as 1, while a "yes" response to question 6 was scored as -1. "No" response were scored as 0. Overall score range -1 to 5.Higher score more indicative of pain with a neuropathic component. Number of participants with score 2 or more (which indicated nerve pain) were reported.	Day 90, Day 180 post-surgery
