Corticosteroids in Total Knee Replacement Surgery

This study is looking at how different steroid medications, when added to a standard pain injection during total knee replacement surgery, affect pain, opioid use, and recovery. Researchers want to see if adding either methylprednisolone or Zilretta (an extended-release steroid) to the standard injection works better than the standard injection alone. They also want to compare Zilretta to methylprednisolone, especially for patients with diabetes. The study will measure pain, range of motion, and patient-reported outcomes for up to a year after surgery. You may be able to join if you are 18 or older, having a primary total knee replacement at specific military or affiliated surgery centers, and meet other criteria. The study aims to enroll 240 participants, but its current status is unclear.

Study design
This is an interventional study with 240 planned participants. It compares three different drug interventions: a standard pain injection (PAI), PAI plus methylprednisolone, and PAI plus Zilretta.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
You would be followed for 24 hours, 72 hours, 7 days, 28 days, 120 days, and 365 days after surgery to assess outcomes.
