Primary Outcome Measures :
  1. The Area Under the Curve (AUC) of the Numeric Rating Scale at Rest (NRS-R) Pain Intensity Scores Through 72 Hours for Subjects Receiving SKY0402 vs. Placebo. [ Time Frame: 72 hours ]
    To assess pain intensity at rest (NRS-R), the subject was to assume a resting position that did not exacerbate his or her postoperative pain and respond to the following question: "On a scale of 0 to 10, where 0 = no pain and 10 = worst possible pain, how much pain are you having right now?"

Secondary Outcome Measures :
  1. Participants With Adverse Events Through 72 Hours or Serious Adverse Events Through 30 Days [ Time Frame: 30 days ]
