• Complications occurring during the surgical procedure or in the period before randomisation as judged by the investigator.
• Acute local or systemic infection at the time of surgery that could confound the post-surgical evaluation.

Primary Outcome Measures

Name	Time	Method
Pain Intensity Difference (PID) on a 0-100 VAS	at 1.5 hours after treatment administration	Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

Secondary Outcome Measures

Name	Time	Method
PID	at 8 hours post-dose.	Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).
