RECRUITINGOpioid Utilization for First 24 Hours Post-Surgery
Opioid utilization for the first 24 hours after surgery, including during surgery, calculated as oral morphine equivalent.
Time frame: Up to Hour 24 Post-Procedure (Post-Operative Day 1 [POD 1])
Length of Stay in PACU
Length of time the patient is in the PACU prior to discharge.
Time frame: Post-Operation (POD 0 - typically up to 3 hours)
Patient-Reported Visual Analogue Scale (VAS) Score - Baseline
Patients rate their pain score on a scale from 0 to 10 (0 being no pain and 10 being the worst imaginable pain); the total score is the response.

Knee injury and Osteoarthritis Outcome Score (KOOS) - Physical Function Shortform (KOOS-PS) Score - Baseline
7-item assessment of how well participants are able to perform different activities. Each item is rated on a 5-point Likert scale (0 to 4), with 0 representing "none" and 4 representing "extreme". The raw score is the sum of responses and is converted to a total score ranging from 0-100, where higher scores indicate greater function.

Kujala Score / Anterior Knee Pain Scale (AKPS) - Baseline
13-item self-report questionnaire that assesses subjective reactions to particular activities and symptoms that are known to correlate with anterior knee pain syndrome. The total score is the sum of responses and ranges from 0 to 100, with 100 being the highest possible score. Lower scores reflect greater pain and disability.
