Knee Injections for Obese Patients With Knee Arthritis

This study is for obese patients (BMI of 30 or higher) who have knee arthritis and are considering a steroid injection. Researchers want to see if a lower dose of triamcinolone acetonide (a steroid) is just as effective as the standard dose for reducing pain and improving knee function. You would receive one of two types of knee injections: either a low dose of 20mg triamcinolone acetonide mixed with lidocaine (a numbing medicine), or a standard dose of 40mg triamcinolone acetonide also mixed with lidocaine. The study will measure your pain and knee function at the start, and then again at 4 weeks and 12 weeks after the injection. The current status of this study is unclear, and it plans to enroll 40 participants.

Study design
This is an interventional study comparing two different doses of a steroid injection. It plans to enroll 40 participants aged 55 to 85.
What's involved
You would receive a knee injection and have your pain and knee function measured at the start, 4 weeks, and 12 weeks.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 12 weeks after the injection to assess pain and knee function.

No other treatment within the time frame of the study.
Patients that are undergoing physical therapy at the time of the study.
  • Numerical Pain Scale (NPS)Baseline, 4 weeks, 12 weeks

    The Numerical Pain Scale (NPS) uses a 0-10 point rating system in which the patient selects the number that describes their current pain level, where "0" represents "no pain" and "10" represents "the worst pain imaginable"

  • Knee Injury and Osteoarthritis Outcome score (KOOS)Baseline, 4 weeks, 12 weeks

    The Knee Injury and Osteoarthritis Outcome is a commonly used questionnaire which focuses on how patients are affected by osteoarthritis symptoms in five areas: knee pain, stiffness, daily activity, sport and recreation, and quality of life. Results are scored 0-100. 0 = extreme problems, 100 = no problems.
