Recruiting studies
- NCT04992624RecruitingPhase 2
Cannabinoid treatment effects on knee pain and nerve signals
This Phase 2 study tests whether a cannabinoid-related treatment changes how pain works in people with knee osteoarthritis. It uses questionnaires, MRI, and gentle nerve testing to understand if treatment helps pain and pain-related signals.
Ann Arbor, MichiganAges 21–75 - NCT06328062Recruiting

This study looks at how knee osteoarthritis pain works and aims to build a computer model to better understand it. By joining, you may help doctors improve future treatments for chronic knee pain.
Herndon, VirginiaAges 18–99 - NCT04576078RecruitingPhase 2
Nefopam for less pain after knee replacement surgery
This Phase 2 study tests whether oral nefopam can reduce pain after total knee replacement done with spinal anesthesia. It looks at whether this medicine works better than the usual post-surgery pain plan and how safely it can be used.
Lyon, LyonAges 18–75 - NCT05761015RecruitingPhase 4
Test of an NSAID to help osteoarthritis pain when walking
This trial studies whether taking an anti-inflammatory pain medicine (an NSAID) can reduce hip or knee osteoarthritis pain during walking. It may help people who have had walking pain for at least 3 months and don’t already take NSAIDs.
Clermont-FerrandAges 50–70 - NCT05788016Recruiting
Help planning an opioid taper before knee or hip surgery

Birmingham, AlabamaAges 18 years+ - NCT06586840Recruiting
Adding an extra nerve block to knee replacement
This trial tests if adding a special nerve block behind the knee (IPACK) to a standard thigh block helps control pain better after total knee replacement. It may lead to less pain and faster recovery.
AydinAges 18–85 - NCT06784882RecruitingPhase 4
Continuous vs. single-injection nerve block for outpatient knee replacement
This trial compares two types of nerve blocks for pain control after total knee replacement. You will receive either a one-time injection or a continuous block that delivers medication through a small tube. The goal is to see which method provides better pain relief while allowing you to go home the same day.
La Jolla, CaliforniaAges 18 years+ - NCT07271849RecruitingPhase 4
Timing of Nalbuphine for Pain and Blood Pressure in Older Knee Surgery Patients
This study tests whether giving the pain medicine nalbuphine at different times during knee replacement surgery affects blood pressure and pain control in older adults. It may help find the best timing to reduce pain and keep vital signs stable.
Jinan, ShandongAges 65–90 - NCT06580561Recruiting
Exercise and insomnia treatment for knee pain
This study combines a gentle exercise program with a treatment for insomnia to see if it helps older adults with knee osteoarthritis feel less pain and sleep better. You will attend group exercise classes and receive sleep coaching.
Ann Arbor, MichiganAges 50 years+ - NCT06753019Recruiting
Knee Osteoarthritis: Thoughts, Feelings, and Function
This study looks at how your thoughts and feelings about knee pain (and your daily function) relate to osteoarthritis. It aims to help understand your overall health better.
IspartaAges 40–84 - NCT06956222Recruiting
Home vs in-person rehab for knee osteoarthritis
This study compares doing physical therapy exercises at home through a video call (tele-rehab) versus doing them in person at a clinic. It is for people with mild to moderate knee osteoarthritis to see if home rehab works just as well.
JeddahAges 40–80 - NCT07425457Recruiting
Cold nerve treatment before knee replacement surgery
This trial tests a cold therapy on nerves before knee replacement to reduce pain. It may help you recover with less discomfort after surgery.
AthensAges 18 years+ - NCT07242170Recruiting
Comparing nerve blocks for pain after knee replacement surgery
This trial tests if adding extra nerve blocks (sciatic, BiFeS, or IPACK) to the usual adductor canal block can reduce pain after total knee replacement. The goal is to find a better way to manage pain and improve recovery.
Erzincan, MerkezAges 18–75 - NCT06074744Recruiting
Nerve blocks for knee replacement pain relief
This study compares two types of nerve blocks (subsartorial and femoral) to see which provides better pain control after knee replacement surgery. Both are injections that numb the nerves around your knee to help with recovery.
LucerneAges 18 years+ - NCT06684587Recruiting
Telehealth exercise and mindfulness for knee osteoarthritis pain
This study tests whether a telehealth program combining exercise and mindfulness can help reduce knee pain from osteoarthritis. It is designed for people who have had knee pain for at least 3 months and can attend sessions remotely.
Boston, MassachusettsAges 50 years+ - NCT06878417Recruiting
Cannabinoids for osteoarthritis knee or hip pain
This study tests if cannabinoid medications can reduce pain interference in daily life for people with hip or knee osteoarthritis. It may be a new option for moderate to severe pain.
Toronto, OntarioAges 40–80 - NCT07354542Recruiting
Relaxation therapy for pain and sleep after joint replacement
This trial tests if different relaxation methods, such as breathing exercises or virtual reality, can help reduce pain and improve sleep after hip or knee replacement surgery. It is designed for people who have had a joint replacement and are able to use a mobile phone or tablet.
Bartın, CenterAges 18 years+ - NCT03747146Recruiting
Enhanced recovery plan for knee replacement pain control
This study tests an “enhanced recovery” approach for people getting total knee replacement, focused on better pain control using regional anesthesia and a home pain medicine plan. It may help you recover more comfortably and follow the care plan more smoothly after surgery.
New York, New YorkAges 18–65 - NCT06426251Recruiting
Light therapy for knee replacement recovery
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.
HsinchuAges 20 years+ - NCT02844751RecruitingPhase 2
Regenerative knee cell therapy for arthritis pain and swelling
This Phase 2 study tests a patient’s own (autologous) regenerative cell treatment to reduce knee pain and inflammation from osteoarthritis. It mainly looks at whether the treatment is safe and whether it can improve symptoms over time.
Grove City, PennsylvaniaAges 18–90 - NCT07324109Recruiting
Testing a system for phantom limb pain after leg amputation
This trial is testing a system called Suralis to see if it can help evaluate phantom limb pain — pain that feels like it's coming from a missing leg. It's for people who have had a leg amputated below or above the knee, use a prosthetic regularly, and have daily pain scoring at least 3 out of 10.
Wiesbaden, HesseAges 18 years+ - NCT07731737Recruiting
Biofeedback vs foam roller for knee osteoarthritis
This trial compares two non-surgical therapies—pressure biofeedback and foam rolling—to see which better reduces pain, improves muscle function, and boosts quality of life in people with early-stage knee osteoarthritis.
LahoreAges 45–65 - NCT07548567Recruiting
Nerve Block to Reduce Pain During Below-Knee Fracture Surgery
This study tests a nerve-blocking injection (numbing medicine around the femoral artery nerve in your groin area) to help reduce pain and blood pressure changes during below-knee fracture surgery when a tourniquet (pressure cuff) is used. The goal is to see if this approach makes surgery more comfortable and safer.
