Recruiting studies
- 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+ - 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+ - 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+ - 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 - 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 - 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 - 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 - 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+ - NCT05828810Recruiting
Testing antiseptic skin cleaning during hip or knee revision surgery
This study checks whether an antiseptic method for cleaning the skin before surgery is safe and helpful for patients having a repeat (revision) hip or knee replacement. It may help reduce the risk of infection related to surgery.
Barrie, OntarioAges 18 years+ - 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+ - NCT06847113Recruiting
Walking Speed Before and After Knee Replacement
This study follows people who are getting a knee replacement to see how their walking speed changes over time—both when they walk at their own pace and as fast as they can. It helps doctors understand recovery better.
OsloAges 55 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.
SinopAges 18 years+ - NCT07337772Recruiting
Comparing corticosteroid doses in knee replacement pain relief injection
This study compares different doses of a corticosteroid (an anti-inflammatory medicine) injected into the knee during total knee replacement surgery. The goal is to see which dose provides the best pain relief after surgery. It is for people having their first knee replacement due to osteoarthritis.
Fuzhou, FujianAges 18–100 - NCT06239649Recruiting
Nerve block before knee replacement for faster recovery
This trial tests whether a numbing injection (nerve block) around the knee before surgery can help you recover faster and feel less pain after a total knee replacement. It is for people with knee osteoarthritis who are ready for their first knee replacement surgery.
Denizli, PamukkaleAges 40–85 - NCT06617871Recruiting
Comparing two ways to align a new knee replacement
This study compares two different techniques (mechanical alignment vs. kinematic alignment) used during knee replacement surgery with a special knee system. It aims to see which technique leads to better results for patients.
Chicago, IllinoisAges 21–79 - NCT07532785Recruiting
Water and Land Exercise Before Knee Replacement Surgery
This trial tests whether a 6-week program combining weekly water-based exercise and three times weekly land-based training can help reduce knee pain and improve strength before total knee replacement surgery. The program aims to help you recover better after your operation.
London, EnglandAges 18 years+ - NCT04960098Recruiting
Survey after hip or knee replacement surgery
This study asks people who have had a hip or knee replacement to share how they’re doing over time. It’s testing whether patient-reported survey answers can help measure recovery and outcomes.
MilanAges 18 years+ - NCT07199738Recruiting
Knee replacement study with a new implant option
This study tests a specific knee implant insert (LEGION Medial Stabilized) in people who need a total knee replacement due to arthritis or similar joint disease. It aims to see if the device is safe and works well over time.
Newton, MassachusettsAges 18–80 - NCT05288803Recruiting
Personalized rehab plans for veterans after knee replacement
This study tests whether customizing a recovery plan (“trajectory”) can improve rehabilitation for veterans after total knee replacement surgery. You may be eligible if you start outpatient rehab soon after surgery at participating clinics.
Aurora, ColoradoAges 40–90 - NCT06740214RecruitingPhase 3
Different doses of liposomal bupivacaine for knee replacement pain
This trial tests different doses of a long-acting painkiller (liposomal bupivacaine) injected into a nerve block in the thigh to see which dose works best for pain after knee replacement surgery. It may help you have better pain control and recover faster.
Hong Kong, Hong KongAges 18–80 - NCT07050277RecruitingPhase 3
Morphine for bladder issues after knee replacement
This study tests whether adding morphine to spinal anesthesia can reduce trouble urinating after a second knee replacement surgery. It may help you avoid needing a catheter after surgery.
Toronto, OntarioAges 21 years+ - NCT04692714Recruiting
Cemented vs cement-free robotic knee replacement surgery

- Yes. Clin2 currently lists 228 recruiting knee arthroplasty 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 knee arthroplasty 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 knee arthroplasty 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.
