About this trial
The goal of this clinical trial is to compare different peri-incisional local infiltrative anesthesia (PLIA) methods in patients ages 13 to 50 undergoing a periacetabular osteotomy (PAO). The main questions to answer here are:
1. Does PLIA impact post-operative pain after PAO? 2. Does PLIA impact pain medication usage as measured by morphine equivalent dosing (MED) after PAO? 3. Does the timing of PLIA administration impact post-operative pain and MED after PAO? Participants will be asked to complete some surveys; demographics survey, General Self-Efficacy Scale (GSE) and the Pain Resilience Scale. All other information will be gathered from the patients medical chart.
Researchers will compare three groups. 1.) Patients who do not receive PLIA. 2.) Patients who receive PLIA after their incision is closed. 3.) Patients who receive PLIA throughout PAO.

Treatment groups
Trial outcomes
Primary outcomes
Post-operative pain after periacetabular osteotomy.
Severity of pain will be measured by collection of the visual analog scale (VAS) for pain. Scale of 1-10.
Pain medication usage after periacetabular osteotomy.
The amount of pain medications taken will be measured using morphine equivalent dosing (MED).
The impact of timing of PLIA administration on post-operative pain.
The mean VAS pain will be compared between the different study groups. Scale of 1-10.
The impact of timing of PLIA administration on MED.
The mean MED will be compared between the different study groups.
Secondary outcomes
Assessment on depression (PHQ-9)
A scale to measure depression will be collected to determine the impact on early post-operative pain. Scale of 0-27.
General Self-Efficacy Scale (GSE)
Scale on self-efficacy will be collected to determine the impact on early post-operative pain. Scale of 10-40
Pain Resilience Scale.
Scale on pain resilience (grit) will be collected to determine the impact on early post-operative pain. The scale provides two scores, Behavioral Perseverance on a scale of 0-20 and Cognitive/Affective Positivity on a scale of 0-36.
