Tramadol and oxycodone vs oxycodone alone for joint pain
This trial tests if taking two pain relievers (tramadol and oxycodone) together works better than oxycodone alone to control pain after knee or hip replacement surgery. It aims to find a more effective way to manage pain with fewer side effects.
Rochester, MinnesotaAges 18 years+ - NCT07047079Enrolling by invitation
Pre-surgery exercise program for knee replacement patients
This trial tests a patient-navigation-based exercise program for people scheduled for knee replacement surgery. The goal is to see if doing exercises before surgery helps with recovery.
Guangzhou, GuangdongAges 45–90 - NCT06800846Enrolling by invitationPhase 4
Pain relief after knee replacement: injection methods compared
This study compares two ways to give pain medicine during knee replacement surgery: one is injected into the bone, the other around the joint. Researchers want to see which works better and may help you recover with less pain.
Khlong Luang, Changwat Pathum ThaniAges 50–80 - NCT06670651Enrolling by invitation
Study of a new total knee replacement system
This trial is testing a new knee replacement system called LinkSymphoKnee. It is for people needing a first-time total knee replacement to help reduce pain and improve function.
Birmingham, AlabamaAges 18–79 - NCT05936814Recruiting
Study measures knee alignment in severe varus osteoarthritis
This study focuses on people age 65+ with severe “varus” knee alignment osteoarthritis (wear-and-tear arthritis that affects how the knee lines up). It aims to use your knee measurements and data to better understand the condition and guide care.
AnkaraAges 65 years+ - NCT06127719Recruiting
Surgery wait time and knee replacement quality of life
This study looks at how waiting for knee replacement surgery affects your quality of life. It may help doctors understand how to improve care for people waiting for surgery.
Hoorn, North HollandAges 18–100 - NCT06383936Recruiting
Knee replacement for active sports lovers
This study tests a new knee replacement designed for active people ages 40 to 65 who used to play sports but had to stop due to knee pain. It aims to see if the implant helps you return to your favorite activities.
BolognaAges 40–65 - NCT06522087Recruiting
40 Hz brain stimulation to prevent confusion after hip or knee replacement
This trial tests if a non-invasive 40 Hz brain stimulation can prevent delirium (sudden confusion) in older adults after hip or knee replacement surgery. Delirium is common after surgery in elderly patients, and this treatment aims to lower that risk.
Zhengzhou, HenanAges 65–85 - NCT06787417RecruitingPhase 4
Knee alignment study for total knee replacement
This study compares two different surgical techniques for total knee replacement to see which one leads to better knee movement and function. If you need a knee replacement due to arthritis, this trial may help find the best approach for your surgery.
Hamilton, OntarioAges 18 years+ - NCT03869996Recruiting
Fast-track recovery for knee replacement patients
This trial studies a faster recovery “fast-track” plan for people getting their first total knee replacement for arthritis. It may help by getting you back to movement and normal life sooner, while comparing outcomes against usual care.
BolognaAges 18–78 - 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 - NCT05302934Recruiting
Testing a knee-surgery app and sensor after knee replacement
This trial checks whether a data platform that uses a wearable sensor and a phone app works well for people getting a total knee replacement. It may help make follow-up care more organized and easier by capturing recovery information.
Konstanz, Baden-WurttembergAges 18 years+ - NCT07767097Recruiting
Low-dose radiation after revision knee replacement for stiffness
This study tests whether a single low dose of radiation after revision knee replacement surgery can help reduce stiffness and improve knee movement in people who had a stiff knee after their first replacement. The radiation is given along with usual care after surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT06298721Recruiting
Personalized care to improve knee replacement satisfaction
This study tests a personalized approach to knee replacement surgery designed for people who are at higher risk of being dissatisfied after the procedure. The goal is to see if tailoring care based on patient-reported outcomes can improve satisfaction.
Cleveland, OhioAges 18–80 - NCT06701474Recruiting
Knee replacement recovery: comparing body composition groups
This study looks at how well people recover after total knee replacement, comparing those with different body composition levels. The goal is to see if a measure called 'phase angle' affects recovery of strength and function.
Yongin-si, Gyeonggi-doAges 55 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.
