Knee injection study: needle size and numbing spray effect
Part of Bones, joints & muscles clinical trials.
This study looks at whether using a thinner needle or a numbing spray (ethyl chloride) reduces pain during a steroid knee injection. It may help people with knee osteoarthritis who need injections feel more comfortable.

This study tests whether a single steroid injection in the healthy knee (the one not being replaced) can reduce pain and improve recovery after total knee replacement. It may help people who have arthritis in both knees but are only having one replaced now.
This study tests a new investigational medicine injected into the knee to see if it is safe and tolerable for people with painful knee osteoarthritis. It may help reduce pain and improve knee function.
This study tests a new knee injection called CX-011 to see if it can reduce pain and improve function in people with knee osteoarthritis. It may be a good option if you have tried other treatments without enough relief.
This study tests if an injection made from amniotic fluid can reduce knee pain and improve function in people with moderate knee osteoarthritis. The goal is to give a long-lasting alternative to steroid or gel shots.
This early (Phase 1) study looks at which anesthetic (numbing medicine) works best and is safest during steroid injections for knee osteoarthritis. It may help improve comfort and effectiveness of these common pain-relief shots.
This trial tests whether adding a steroid to spinal anesthesia can make the numbness last longer during knee arthroscopy. Knee arthroscopy is when a doctor looks inside your knee with a small camera.
