This study is looking at ways to make knee injections for osteoarthritis (OA) less painful. Researchers want to see if using a smaller needle (25 gauge) or a numbing spray called ethyl chloride (or both) can reduce the pain you feel during and right after the injection. They will compare these to a slightly larger needle (22 gauge) and a placebo spray (isopropyl alcohol). The study will also look at how factors like fear of needles might affect your pain experience and if less pain during the injection leads to better long-term results for your knee. To join, you need to be between 40 and 89 years old, have knee osteoarthritis, and be scheduled for a steroid injection in your knee. The study is currently unclear on its recruitment status.

Study design

This interventional study plans to enroll 88 participants. It will compare different needle sizes and the use of ethyl chloride spray during knee injections.

What's involved

You would receive an intra-articular knee joint injection with steroids. Your pain will be measured immediately after the procedure and 24-48 hours later.

Compensation

Not stated in the trial record.

Follow-up

The study will assess improvements in knee osteoarthritis pain and functional scores at 6 weeks after the injection.
