Recruiting studies
- NCT06971757Recruiting
Is yearly check-up after hip or knee replacement needed?
This study looks at whether routine check-ups one year after hip or knee replacement are helpful or unnecessary. If you've had or are scheduled for a first hip or knee replacement for arthritis, you may be able to join.
AmsterdamAges 50 years+ - 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+ - NCT07634523RecruitingPhase 4
Amino acids to prevent muscle loss after knee surgery
This study tests whether a supplement containing branched chain amino acids (special protein building blocks) can help prevent muscle loss in older adults having knee replacement surgery. The goal is to help patients recover strength and mobility more quickly after their operation.
Seongnam-si, Gyeonggi-doAges 40–100 - NCT04814082Recruiting
Compare two knee implant types for walking and function
This study compares two designs of knee replacement implants to see how they affect walking, function, and outcomes after surgery. You may be randomly assigned to one of the implant types used for your specific, approved knee replacement.
Baltimore, MarylandAges 18–75 - NCT07360392Recruiting
Nerve block comparison for knee replacement pain
This study compares two numbing techniques (nerve blocks) for pain relief after knee replacement surgery. The goal is to find which one works better and helps you recover with less pain.
AmasyaAges 18–80 - NCT05314491Recruiting
Follow-up study after knee replacement with a specific implant
This study follows people after they get a total knee replacement using the Multigen Plus system, sometimes with special cone pieces. It looks at how well the implant performs over time and whether results meet expectations.
GuimarãesAges 18 years+ - NCT07127042RecruitingPhase 2
Testing a drug to reduce bleeding during knee replacement
This trial tests an experimental drug called BT-114143 to see if it reduces bleeding during and after total knee replacement surgery. It may be a good option for people with osteoarthritis who are having their first knee replacement.
Chengdu, Si'ChuanAges 18–70 - NCT07092982Recruiting
Comparing two numbing methods for knee replacement surgery
This study compares two different numbing techniques to see which provides better pain control during and after total knee replacement. It may help find a way to reduce pain and improve recovery.
IstanbulAges 18–75 - NCT06640491RecruitingPhase 1/Phase 2
Antibiotics via bone injection for knee replacement
This study tests giving antibiotics (cefazolin and vancomycin) through a small needle into the shin bone during knee replacement surgery. The goal is to see if this way of giving antibiotics works well to prevent infection.
Houston, TexasAges 18 years+ - NCT07021287Recruiting
Cold therapy after knee replacement surgery
This study compares different cold therapy programs to see which works best for pain and swelling after total knee replacement. Everyone in the study receives cold therapy, and the researchers will track recovery outcomes.
Yiwu, ZhejiangAges 18 years+ - NCT06634654Recruiting
AI-guided knee replacement study
This trial tests whether using artificial intelligence can improve recovery from total knee replacement by tailoring care to your body's needs. It may help people with severe knee arthritis who have not had major knee surgery before.
Rome, ItalyAges 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+ - NCT07561333Recruiting
Pain Relief Methods for Knee Replacement Surgery
This study compares two different nerve-blocking anesthesia techniques to see which one controls pain better after knee replacement surgery. Both methods are designed to numb the area around your knee so you need less pain medication afterward.
Çorum, CentreAges 18–80 - NCT07437469Recruiting
Binaural beats for pain and anxiety after surgery
This trial tests if listening to binaural beats (a type of sound therapy) after hip or knee replacement surgery can help reduce pain and anxiety. You would receive the sound therapy through headphones while in the recovery room.
Miami, FloridaAges 18–99 - NCT04884542Recruiting
Testing a knee replacement implant for total knee arthroplasty
This study looks at outcomes after surgery using the Multigen Plus H knee replacement system, sometimes with special add-on parts called AMF TT cones. It may help improve how well these knee implants work and how patients recover after total knee replacement.
GhentAges 18 years+ - NCT07080892Recruiting
Comparing two ways to give a knee nerve block for pain after knee replacement
This study compares two different ways of giving a nerve block (called iPACK) to see which works better for pain after total knee replacement. The goal is to find the best spot for the injection to help you feel more comfortable after surgery.
BratislavaAges 18–80 - NCT04848896Recruiting
Safety and outcomes study of a smart knee replacement
This trial studies whether a “smart” knee replacement system (CORI) is safe and works well for people getting a total knee arthroplasty (TKA). If you’re a good candidate for a cemented standard knee replacement, the study follows you for two years to check results after surgery.
EppingAges 18 years+ - NCT07110324Recruiting
Understanding long-term pain after hip or knee replacement
This study looks at people who still have moderate to severe pain months after a hip or knee replacement. The goal is to learn more about what causes this pain and how it feels, which could help improve future treatments.
Østerbro, København ØAges 18 years+ - NCT06969222Recruiting
Robotic knee replacement study with a special implant
This study tests a robot-assisted knee replacement using a new type of implant designed to move more like a natural knee. It may help people with arthritis or other knee joint problems who need a total knee replacement.
Larissa, ThessalyAges 18–95 - NCT07544264Recruiting
Five-Year Knee Replacement Outcomes Study
This study follows patients who receive a new knee joint replacement for severe knee arthritis or similar conditions. Researchers will track how well the artificial knee works and how patients recover over 5 years to ensure the replacement lasts and improves quality of life.
BolognaAges 50–85 - NCT06293352Recruiting
Comparing two antibiotic spacers for knee infection
This trial compares two types of antibiotic spacers for people with a long-term knee replacement infection. It tests whether a spacer made entirely of antibiotic cement or one with a metal core works better to treat the infection before a new knee replacement.
Chicago, IllinoisAges 18 years+ - NCT07212699Recruiting
Knee osteoarthritis app-based outcome score study
This trial uses a smartphone app to track symptoms in people with knee osteoarthritis or a knee replacement. The goal is to develop a better way to measure how patients are doing.
Munich, BavariaAges 18 years+ - NCT07442435Recruiting
Reiki for recovery after knee replacement surgery
This study tests whether adding Reiki (a gentle hands-on relaxation therapy) to standard care helps people feel better and recover more comfortably after a first-time knee replacement. It may be a good fit if you are having your first knee replacement, are not on certain medications, and haven't tried energy therapies before.
