Lipedema's role in knee arthritis in women
This study compares women with knee arthritis who do or don't have lipedema (a condition causing painful fat buildup, usually in the legs) to understand how lipedema affects knee joint health. Results may help doctors better treat knee arthritis in women with lipedema.
Izmir, İzmirAges 30–65 - NCT07848126Recruiting
Foam rolling after knee replacement surgery
This study tests whether using a foam roller after knee replacement surgery helps reduce pain and improve movement. If you are having your first knee replacement, this may help you recover faster.
Izmir, BalçovaAges 40 years+ - 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+ - NCT07522489Recruiting
New knee replacement surgery guidance methods compared
This study compares two ways doctors use computer guidance during robotic knee replacement surgery for severe knee arthritis. The trial tests whether both methods work equally well or if one is better for patient recovery and results.
Warsaw, MazovianAges 18 years+ - NCT06010979Recruiting
Knee replacement with digital help study
This study looks at knee replacement surgery done with digital tools like robots or computer guidance. It may help people with knee arthritis find better ways to have surgery and recover.
Beijing, Beijing MunicipalityAges Any age - NCT07864896RecruitingPhase 3
Study of a new pain medicine after knee replacement surgery
This trial tests a new oral pain medicine called suzetrigine for people who have a knee replacement. It aims to see if it helps control pain after surgery better or with fewer side effects than usual care.
New York, New YorkAges 18–80 - NCT07785401Recruiting
Platelet-rich plasma plus hyaluronic acid for knee osteoarthritis
This study tests whether adding platelet-rich plasma (PRP) to hyaluronic acid injections improves knee osteoarthritis pain and function better than hyaluronic acid alone. You may be eligible if you have moderate knee osteoarthritis and no other knee problems.
Warsaw, Masovian VoivodeshipAges 18 years+ - NCT07784907Recruiting
Platelet-rich plasma and hyaluronic acid for knee arthritis
This trial tests whether a combination of platelet-rich plasma (a concentrate from your own blood) and hyaluronic acid (a joint lubricant) helps reduce pain and improve function in people with knee arthritis. You may be eligible if you have moderate knee pain but your other knee is relatively pain-free.
Chełm, Lublin VoivodeshipAges 18 years+ - NCT06839807Recruiting
Testing a new device for knee replacement loosening
This study tests a new device (AtMoves Knee System) to help diagnose if a knee replacement is loose. It is for people who have had a knee replacement and have symptoms that might mean the implant is loose, but standard tests have not given a clear answer.
Nijmegen, GelderlandAges 18 years+ - NCT07121556Recruiting
Fat tissue vs fat tissue plus gel for knee osteoarthritis
This trial compares two injections for knee arthritis: one uses your own fat tissue, the other adds a lubricating gel. Researchers want to see if the combination helps pain and function more than fat tissue alone.
BolognaAges 18–75 - NCT06968143Recruiting
Patient Satisfaction With Smart Knee Implants Trial
This trial looks at how satisfied patients are with a new 'smart' knee implant that tracks motion and function. If you are getting a total knee replacement, you might be able to join and help compare the smart implant with standard implants.
Chicago, IllinoisAges 18 years+ - NCT05290818Recruiting
Robotic vs standard knee replacement for inner-joint wear
This trial compares robotic-assisted knee replacement with the usual (non-robotic) approach for people with severe arthritis on the inner (medial) side of the knee. It aims to see which method works better for pain and function while matching the right knee anatomy for certain implant types.
Edinburgh, LothianAges 50–75 - NCT04247672Recruiting
Study of knee replacement outcomes using a specific knee implant
This study follows people who need knee replacement for “end-stage” knee osteoarthritis and will receive a specific knee implant system as part of routine care. It aims to measure how well the knee replacement works for patients over time, which may help improve future care.
Hoofddorp, North HollandAges 21–90 - NCT04275362Recruiting
Walking analysis after a specific knee replacement design
This study looks at how people walk after receiving a particular total knee replacement design. It compares movement patterns (gait analysis) to help understand how well the knee works in real life.
Phoenix, ArizonaAges 50 years+ - NCT07818343Recruiting
Comparing two knee replacement designs for revision surgery
This study compares two types of knee implants used when a previous knee replacement needs to be revised (re-done). It aims to see which design offers better outcomes for patients needing both parts of the implant replaced.
Washington D.C., District of ColumbiaAges 18–80 - NCT07552415Recruiting
Joint Immobilization After Knee Replacement Revision Surgery
This study tests whether keeping your knee still for a period after revision knee replacement surgery helps improve how well you can bend and straighten it. Researchers want to see if immobilization (using a brace or cast) helps you regain better movement compared to standard care.
New York, New YorkAges 18 years+ - NCT07504562Enrolling by invitationPhase 2
Ejiao Paste for Knee Osteoarthritis Pain
This trial tests a traditional Chinese medicine patch called Knee Pain Ejiao Paste for knee osteoarthritis pain. It aims to see if the paste reduces pain and improves function compared to a placebo.
Shanghai, Shanghai MunicipalityAges 40–75 - NCT06676189Recruiting
Comparing two types of plastic knee implants for replacement
This study compares two different types of plastic knee implants (polyethylene) used in total knee replacement surgery. The goal is to see which one works best for patients with knee arthritis.
Clermont-FerrandAges 18–90 - NCT03286868Recruiting
Tested knee replacement alignment during knee surgery
This study looks at how a specific computer/measurement approach (“Verasense”) helps position the knee during total knee replacement for people with knee arthritis. It may help improve how the new knee fits and aligns as you recover.
Halifax, Nova ScotiaAges 21–80 - NCT07351981Enrolling by invitation
Cooled radiofrequency for knee osteoarthritis pain
This study tests a new approach called cooled radiofrequency (TcPRF) to calm knee pain from osteoarthritis. It may be an option if standard treatments haven't worked and you haven't had certain other treatments recently.
AthensAges 45 years+ - NCT06891807Recruiting
Robotic vs augmented reality knee replacement
This study compares two advanced technologies for total knee replacement: a robot that uses a CT scan for guidance versus an augmented reality system that uses no scan. The goal is to see which approach leads to better outcomes for patients with osteoarthritis.
Sint-Martens-Latem, Oost-VlaanderenAges 18–85 - NCT06859164RecruitingPhase 2
Knee artery treatment for chronic osteoarthritis pain
This trial tests a procedure called genicular artery embolization to reduce pain in people with knee osteoarthritis that hasn't improved with other treatments. The goal is to see if blocking certain blood vessels can relieve pain and help you avoid or delay knee replacement surgery.
