| AUC-VAS With Movement (Post-operative Period, Hour-6-28) | Study hour-6 through hour-28 | Measurement of the patient's self assessment of pain with movement using the validated visual analog scale (VAS) during the post-operative period (study hour-6 through hour-28). VAS assessments document the patient's self reported level of pain from No pain (0 mm) to Worst possible pain (100 mm) on a 100 mm line. VAS assessments were performed immediately following surgery \[variable since every surgery has a unique length of time even if it is the same procedure\] and at hours 6, 8, 12, 16, 20, 24 and 28 (for the primary endpoint). |

Outcome results
AUC-VAS With Movement (Post-operative Period, Hour-6-28)
Measurement of the patient's self assessment of pain with movement using the validated visual analog scale (VAS) during the post-operative period (study hour-6 through hour-28). VAS assessments document the patient's self reported level of pain from No pain (0 mm) to Worst possible pain (100 mm) on a 100 mm line. VAS assessments were performed immediately following surgery \[variable since every surgery has a unique length of time even if it is the same procedure\] and at hours 6, 8, 12, 16, 20, 24 and 28 (for the primary endpoint).
Time frame: Study hour-6 through hour-28
Population: Efficacy analyses were performed on the Intent to Treat (ITT) population and the Efficacy Evaluable Population (EEP). All randomized patients who received at least a partial dose of CTM were included in the ITT analyses. All data below represents the ITT analyses.
