Recruiting studies
- NCT05842538Recruiting

Comparing knee function in people with similar knee arthritis pain
This study looks at how knee osteoarthritis (a common condition where the cushioning in the knee joint wears down) affects physical function, even when people report similar levels of pain. It aims to understand why some people with the same pain might have more difficulty with daily activities, which could lead to better targeted treatments.
MardinAges 40–75 - NCT07865325Enrolling by invitation
Light therapy for knee pain in teenage girls
This study tests whether a special light treatment can reduce knee pain in teenage girls. If it works, it could offer a drug-free way to ease discomfort and help you move more comfortably.
AmmanAges 14–18 - NCT07855367Recruiting
Knee pain relief study for osteoarthritis patients
This study compares two procedures that use extreme cold or heat to target the nerves around the knee, with the goal of reducing pain from knee osteoarthritis. It is specifically for people with advanced knee osteoarthritis who also have bladder cancer.
CairoAges 40 years+ - NCT03491761RecruitingPhase 2
PRP injection versus hyaluronic acid shots for knee arthritis
This trial tests whether a platelet-rich plasma (PRP) shot works better than a standard hyaluronic acid (“gel”) injection to reduce knee osteoarthritis pain. It may help people with ongoing knee pain choose the treatment that relieves symptoms more effectively.
Skokie, IllinoisAges 18–75 - NCT06108063RecruitingPhase 1/Phase 2
Losartan to prevent knee stiffness after replacement
This study tests whether losartan, a blood pressure medicine, can prevent excessive scar tissue (arthrofibrosis) after a total knee replacement. Participants receive losartan or a placebo for 6 months after surgery to see if it improves knee motion and reduces stiffness.
Vail, ColoradoAges 18 years+ - NCT04801654Recruiting
Knee replacement study using a specific metal implant coating
This study looks at outcomes after a primary knee replacement using the GMK Sphere TiNb implant. It may help researchers learn how well this specific implant works and how patients do over time.
Milan, MIAges 18 years+ - NCT05559463Recruiting
Anti-inflammatory diet for knee arthritis pain relief
This trial studies whether an anti-inflammatory eating plan (the “ITIS diet”) can improve symptoms in people with knee osteoarthritis. It is meant to see if changing what you eat can help reduce pain and improve function.
La Jolla, CaliforniaAges 18 years+ - NCT06195423Recruiting
Stopping knee arthritis after an ACL tear
This study tests a home exercise program to prevent knee arthritis after an ACL tear. If you had ACL surgery 9 to 36 months ago and still have some knee symptoms, this program may help protect your knee in the long run.
Vancouver, British ColumbiaAges 16–35 - NCT07853170Recruiting
Comparing 3 vs 5-needle knee nerve blocks for arthritis pain
This study compares two ways of numbing the nerves around the knee to see which gives better pain relief and improves quality of life for people with knee osteoarthritis. It might help you decide if a nerve block is a good option for your knee pain.
Tanta, El-GharbiaAges 18 years+ - NCT06442319Recruiting
PRP after ACL reconstruction
This trial tests if injecting platelet-rich plasma (a concentration of your own blood platelets) after ACL reconstruction helps with healing and reduces pain. It's for people who recently had ACL surgery and want to try an extra treatment to improve recovery.
TorunAges 18–45 - NCT07843784Enrolling by invitation
Chatbot pain management for knee osteoarthritis
This trial tests a chatbot program to help people manage knee osteoarthritis pain. You’d use your smartphone to get support and exercises at home, which might help reduce pain and improve daily life.
Hong Kong, Hong KongAges 18 years+ - NCT07842913Recruiting
Hybrid telerehabilitation for anterior knee pain
This study tests a hybrid telerehabilitation program for people with anterior knee pain. It combines at-home exercises with remote physiotherapy sessions using a smartphone app. The goal is to see if this approach is effective in routine clinical practice.
BrusselsAges 18 years+ - NCT05933434RecruitingPhase 1/Phase 2
Stem cell injection trial for chronic knee osteoarthritis
This early-phase study tests an injection of donor stem cells placed into the knee joint to help reduce symptoms of knee osteoarthritis. You may be eligible if you have long-lasting knee pain from mild-to-moderate arthritis and meet safety and imaging requirements.
Aarhus NAges 40–75 - NCT05516381Recruiting
Navigation-assisted knee replacement with two alignment methods
This study tests a computer-guided technique for total knee replacement and compares two ways of aligning the new joint. It may help improve how accurately the surgery is done, which could affect comfort and function afterward.
BarcelonaAges 18 years+ - NCT06463847RecruitingPhase 1
Stem cell therapy for knee osteoarthritis
This trial tests a new stem cell treatment (UC-MSCs) for knee osteoarthritis. It aims to see if this treatment is safe and can help reduce pain and improve knee function.
Wuhan, HubeiAges 50–70 - NCT07813078Recruiting
Walking on an anti-gravity treadmill for knee osteoarthritis
This study tests whether walking on a special treadmill that reduces the weight on your knees can help with knee pain and function. If you have knee osteoarthritis, this type of training might be an effective way to exercise without causing more joint stress.
Sanok, Podkarpackie VoivodeshipAges 40–70 - NCT07813832Recruiting
Recovery study after knee or hip replacement
This study looks at why some people have problems after knee or hip replacement surgery. It follows patients for three years to understand complications and improve care.
MoscowAges 45 years+ - NCT07804199Recruiting
Ear nerve stimulation for knee osteoarthritis pain in veterans
This study tests whether a small device that stimulates a nerve in your ear can help reduce knee pain caused by osteoarthritis. If you join, you'll be asked to stop taking your current knee pain medicines during the trial, but you can use a safe rescue medicine (acetaminophen/paracetamol) if needed.
Decatur, GeorgiaAges 45–75 - NCT07807943Recruiting
Knee arthritis pain relief procedure for cancer patients
This study tests a procedure called geniculate artery embolization (GAE) to reduce knee pain from osteoarthritis in people who also have cancer. It may help those who cannot or do not want to have knee surgery.
Houston, TexasAges 40 years+ - NCT06196567Recruiting
Pulsed magnetic therapy for knee strength before replacement
This study tests whether pulsed electromagnetic field therapy (a non-invasive treatment using magnetic pulses) can improve muscle strength and function in people with severe knee osteoarthritis who are waiting for knee replacement surgery. It may help you feel stronger and move better before your operation.
Hong Kong, NEW TerritoriesAges 50–100 - NCT07793266RecruitingPhase 1
Seeing the knee better with dye during arthroscopy
