Recruiting studies
- NCT07577570Recruiting
Calcium Treatment After Thyroid Surgery
This study tests whether calcium supplements help patients whose parathyroid glands aren't working properly after thyroid surgery. The parathyroid glands control calcium levels in your body, and they can be accidentally injured during thyroid removal.
Tallinn, OtherAges 18 years+ - NCT07584356Recruiting
Comparing Shoulder Replacement Methods for Arthritis
This study compares two different surgical approaches for replacing a shoulder damaged by arthritis, but only in patients whose rotator cuff (the muscles that stabilize the shoulder) is still working well. The goal is to find which method works better for your specific situation.
Rochester, MinnesotaAges 60–85 - NCT06724783RecruitingPhase 4
Comparing two collagen membranes for bone growth around dental implants
This study compares two types of collagen membranes used to help rebuild bone around a dental implant. If you need a single implant in the front of your mouth and a bone graft at the same time, this trial may help determine which membrane works best.
Geneva, Canton of GenevaAges 18–90 - NCT06714214Recruiting
Predicting when you can stop kidney dialysis
This trial studies whether a blood test called delta C-cistatin can help doctors predict when patients can safely stop continuous kidney dialysis after acute kidney injury.
BolognaAges 18 years+ - NCT07569549Recruiting
Thumb base arthritis surgery: joint replacement vs bone removal
This study compares two common surgeries for thumb base arthritis to see which one gives better pain relief and hand function. The results could help you and your doctor choose the best treatment option.
UppsalaAges 40–80 - NCT07564427Recruiting
Electromagnetic therapy to reduce pain after hip replacement
This study tests whether a special electromagnetic therapy, added to standard recovery exercises, can reduce pain and improve movement after hip replacement surgery. The therapy is non-invasive and may help you regain function faster.
TaipeiAges 18–99 - NCT07566325Recruiting
Avocado and inflammation: can it improve your health?
This study tests whether eating avocado instead of refined carbohydrate foods (like white bread and sugary snacks) can reduce inflammation markers in your blood. If you have some signs of inflammation and extra weight around your middle, this might help researchers understand if avocado is a helpful dietary change.
Chicago, IllinoisAges 21–74 - NCT07551856Recruiting
Robotic vs. manual knee replacement surgery for arthritis
This study compares two ways to perform knee replacement surgery for osteoarthritis: traditional manual surgery versus robotic-assisted surgery. Both are standard approaches; the trial tests whether robotic guidance improves how well your knee works after surgery.
Glasgow, ScotlandAges 18 years+ - NCT07556523RecruitingPhase 4
Recovery quality after heart valve replacement with different sedation
This study compares how well patients recover after a minimally invasive heart valve procedure (TAVR) when given different types of sedation. The goal is to find which sedation approach helps patients feel better and recover faster after the procedure.
Glenview, IllinoisAges 18–90 - NCT07549542Enrolling by invitationPhase 4
Testing antibiotic delivery method for hip replacement surgery
This study compares a new way of delivering antibiotics directly into the bone during hip replacement surgery versus the standard IV method. The goal is to see if this approach prevents infection just as well while potentially improving outcomes.
Somerset, New JerseyAges 18 years+ - NCT06743568Recruiting
Comparing new valves for tight aortic valve in enlarged aorta
This trial tests two types of replacement heart valves (self-expanding and balloon-expanding) in people who have severe aortic stenosis (tight heart valve) and an enlarged aorta (the main blood vessel from the heart). The goal is to see which valve type works better for these patients.
Beijing, Beijing MunicipalityAges 65 years+ - NCT06750172Recruiting
Shorter salt test for primary aldosteronism diagnosis
This study tests if a 2-day version of the oral salt loading test works as well as the standard 3-day test to diagnose primary aldosteronism (a common cause of high blood pressure). If effective, it could make diagnosis faster and easier for patients.
Beijing, Beijing MunicipalityAges 18–70 - NCT07517588Recruiting
Mitral Valve Repair Using Polares System for Heart Failure
This trial tests a minimally invasive procedure to repair a leaky mitral valve (the valve between the upper and lower chambers of your heart) in people with heart failure who haven't improved with medication alone. The procedure uses a catheter-based system inserted through the groin to replace part of the valve, potentially reducing symptoms and improving heart function.
Atlanta, GeorgiaAges 21 years+ - NCT07511985Recruiting
Managing Pain After Knee Replacement Surgery
This study looks at how "rebound pain" (increased pain when pain medication wears off) affects long-term pain after total knee replacement. Researchers want to understand this connection and potentially improve pain management strategies for knee surgery patients.
Konya, MeramAges 18 years+ - NCT07511673Recruiting
Dental screening before heart valve surgery
This trial tests whether a dental checkup before heart valve surgery can improve recovery and prevent complications. If you are scheduled for a heart valve procedure, you may be able to join.
GothenburgAges 18 years+ - NCT07500922Recruiting
Menopause effects on brain activity study
This study looks at how menopause affects brain signals controlling movement. It offers combined hormone treatment to eligible women.
JyväskyläAges 50–59 - NCT07489963Recruiting
Does keeping the posterior cruciate ligament help after knee replacement?
This trial compares two ways of doing robotic-assisted knee replacement: one that keeps the posterior cruciate ligament (a natural knee stabilizer) and one that doesn't. Researchers will see if saving the ligament leads to better knee function a year after surgery.
BordeauxAges 18 years+ - NCT06704516RecruitingPhase 1
HRT and fatty liver disease in menopausal women – a pilot study
This study tests whether starting hormone replacement therapy (HRT) improves liver health in women with menopause and fatty liver disease (MASLD). It aims to understand how HRT might help reduce fat in the liver.
Oxford, OxfordshireAges 18 years+ - NCT07485803RecruitingPhase 4
Methadone for pain after knee replacement
This study tests whether methadone, a type of pain medicine, helps control pain better after knee replacement surgery. It is for people who have not used narcotics recently and are otherwise healthy.
Denver, ColoradoAges 21–75 - NCT07473089Recruiting
Swiss study on joint replacement revision for infection
This study looks at people who need a second (revision) surgery on a large joint replacement like a hip, knee, shoulder, ankle, or elbow because of a suspected or confirmed infection. The goal is to learn more about these infections and improve care.
AarauAges 18 years+ - NCT05738408Recruiting
Remote smoking help for hospitalized heart patients
This trial tests a phone-based (remote) smoking quit program for people hospitalized for a recent heart-related event. It may help you quit smoking by offering support when you’re in the hospital and afterward.
Burlington, VermontAges 18 years+ - NCT07466745Recruiting
New Pulmonary Valve Study for Kids Needing Replacement
This study tests a new type of replacement valve for children who need a new pulmonary valve (the valve between the heart and lungs). Researchers want to see if the valve works safely and well in real-world use.
Los Angeles, CaliforniaAges 1.5 years–16 years - NCT07464483Recruiting
Studying genetics in stem cell and CAR-T therapy patients
This trial analyzes genetic information from patients receiving a stem cell transplant or CAR-T therapy to better understand treatment outcomes. Participation may help researchers improve future therapies.

Common questions
- Are there clinical trials for replacement?
- Yes. Clin2 currently lists 507 recruiting replacement studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a replacement trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a replacement trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
