Light therapy for pain after knee replacement surgery
Part of Brain & nervous system clinical trials.
This study tests a special light therapy called photobiomodulation (light applied to the skin) to reduce pain after knee replacement surgery. You would receive this treatment on your knee after surgery, and it aims to help you recover with less pain and fewer opioids.
Summary written for real people, not researchers, by Clin2.

This study tests whether low-level laser therapy (a painless, non-surgical treatment using light) can reduce knee pain and improve knee function, cartilage health, and muscle strength in people with moderate knee osteoarthritis. It may be an option if you haven't had recent knee injections or physical therapy.
This study tests a light therapy device called OLIZ that is placed on the skin to help reduce pain after knee replacement surgery. It may offer a drug-free option for managing pain after your operation.
This trial tests whether a special light therapy (photobiomodulation) can help reduce pain and speed healing after total knee replacement. If you're having knee replacement and don't have complications like infection or open wounds, you may be eligible.
This study tests whether a special laser treatment can help improve recovery after knee replacement surgery. If you're still having pain after your surgery, this treatment might help you recover faster and with less discomfort.
This study tests whether a special light therapy (called photobiomodulation) can reduce knee pain and inflammation in people with knee osteoarthritis. If you qualify, you might receive either active light therapy or a sham (inactive) treatment to see if it helps with your chronic knee pain.
This trial tests whether photobiomodulation (a type of laser/light therapy) can reduce chronic pain in both knees for people preparing for bariatric (weight-loss) surgery. If you have knee pain that limits daily life, the treatment may help you feel better while you’re in the pre-surgery rehabilitation period.
