Study Endpoints
Primary Endpoints
Mean Area Under the Curve (AUC) of the Numeric Rating Scale (NRS) Pain Intensity Scores With Activity (NRS-A) Through 72 Hours Postsurgery (AUC0-72), Compared With Saline Placebo.
72 hours

Pain intensity is assessed using an 11-point NRS (0-10) where 0 represents "no pain" and 10 represents "worst pain imaginable" (using windowed worst observation carried forward to adjust for opioid rescue medication use). The theoretical range of AUC0-72 is 0-720. The prescribed activity for NRS-A is sitting with the plantar surface of the ball of the surgically attended foot touching the floor (no weight bearing).

Mean Area Under the Curve (AUC) of the NRS-A (Windowed Worst Observation Carried Forward) Pain Intensity Scores
72 hours

Pain intensity scores are assessed using an 11-point Numeric Rating Scale (NRS) (0-10) where 0 represents "no pain" and 10 represents "worst pain imaginable". NRS scores are recorded with activity (NRS-A), sitting with the plantar surface of the ball of the surgically attended foot touching the floor (no weight-bearing).

Percentage of Subjects Receiving no Opioid Rescue
72 hours
Mean Area Under the Curve (AUC) of the Numeric Rating Scale (NRS) Pain Intensity Scores With Activity (NRS-A) Through 24 Hours Postsurgery (AUC0-24).
24 hours

Pain intensity is assessed using an 11-point NRS (0-10) where 0 represents "no pain" and 10 represents "worst pain imaginable" (using windowed worst observation carried forward to adjust for opioid rescue medication use). The theoretical range of AUC0-24 is 0-240. The prescribed activity for NRS-A is keeping the elbows at the side and against the body and then raising both hands in front of the abdomen with hands clasped and holding that position for at least 5 seconds.

Mean Area Under the Curve (AUC) of the Numeric Rating Scale (NRS) Pain Intensity Scores at Rest (NRS-R) Through 48 Hours Postsurgery (AUC0-48).
48 hours

Pain intensity is assessed at rest using an 11-point NRS (0-10) where 0 represents "no pain" and 10 represents "worst pain imaginable" (using windowed worst observation carried forward to adjust for opioid rescue medication use). The theoretical range of AUC0-48 is 0-480.

Mean Summed Pain Intensity (SPI) Score
24 hours

Subjects assessed pain intensity for their current pain with the 11-point (0 to 10) Numeric Rating Scale NRS where "0" equated to "no pain" and "10" equated to "the worst pain imaginable". Pain intensity was assessed at rest (NRS-R) after the subject had been supine for a minimum of 5 minutes and with activity (NRS-A) sitting up from a supine position. The SPI is derived by summing the pain intensity score weighted by the scheduled time duration. SPI0-24 was calculated by summing the Pain intensity (PI) score at the relevant time points weighted by the scheduled time duration since the prior PI assessment as follows: SPI0-24= PI1+PI2+2\*PI4+2\*PI6+2\*PI8+2\*PI10+2\*PI12+2\*PI14+4\*PI18+6\*PI24. Min = 0 (if PI=0 at every time) and Max = 240 (if PI=10 at every time).
