Recruiting studies
- NCT07371390Recruiting
Minimal sedation for knee replacement surgery
This trial tests whether less sedation during knee replacement surgery can improve recovery. It may help you if you are having your first total knee replacement and can have spinal anesthesia.
Rochester, MinnesotaAges 18 years+ - NCT06608745Recruiting
Computer-assisted vs standard knee replacement study
This trial compares a computer-assisted technique to the standard method for total knee replacement. It aims to see if the computer-assisted approach leads to better clinical and functional outcomes.
BolognaAges 45 years+ - NCT06946368Recruiting
Exparel for pain after knee replacement
This study tests if a long-lasting numbing medicine called Exparel, given by the surgeon during knee replacement, helps control pain after surgery. It is for people having their first total knee replacement on one knee due to arthritis.
Cleveland, OhioAges Any age - NCT06947655Recruiting
Tourniquet types for knee replacement surgery
This study compares different types of tourniquets (tight cuffs) used during knee replacement surgery to see how they affect blood loss and how satisfied surgeons are with them.
Bonn, North Rhine-WestphaliaAges 18 years+ - NCT07727551Recruiting
Nerve block before knee replacement for better recovery
This trial tests if a nerve block given a few weeks before knee replacement surgery can improve pain and function after the operation. It is designed for people who have certain risk factors that might make recovery harder.
BrusselsAges 18–60 - 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 - NCT07539467Enrolling by invitation
Nerve Block and Tourniquet for Knee Surgery Pain Relief
This trial tests whether a nerve block (numbing injection near the thigh) combined with a tourniquet (pressure cuff) after knee replacement surgery reduces pain better than standard care. If it works, it could help patients recover more comfortably with less need for strong pain medications.
AnkaraAges 40–85 - NCT07124494Recruiting
Anesthesia type and recovery after knee replacement
This study compares two types of anesthesia for total knee replacement to see which helps with pain, movement, and satisfaction after surgery. If you are scheduled for a knee replacement and are willing to have a spinal or epidural anesthesia, you may be able to join.
Konya, MeramAges 18 years+ - NCT03519269Recruiting
Robotic versus standard knee replacement for severe knee arthritis
This study compares a robotic-assisted knee replacement to a standard (non-robotic) knee replacement. It may help people with severe knee arthritis learn which approach improves pain and knee function after surgery.
New York, New YorkAges 40–85 - NCT04230616Recruiting
Testing a knee device to ease osteoarthritis pain
This study tests how well and how safely a knee treatment works for adults with painful knee osteoarthritis seen on X-ray. You might join if you need meaningful pain relief and help with daily function, and can complete required scans and study instructions.
Sint-Truiden, LimburgAges 18 years+ - 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 - 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 - 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+ - NCT06809998RecruitingPhase 1/Phase 2
Steroid injection in non-surgical knee before knee replacement
This study tests whether a single steroid injection in the healthy knee (the one not being replaced) can reduce pain and improve recovery after total knee replacement. It may help people who have arthritis in both knees but are only having one replaced now.
Toronto, OntarioAges 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+ - NCT05800457Recruiting
Test synovectomy to reduce pain after knee replacement
This study looks at whether a procedure called synovectomy (removing inflamed joint lining) can reduce pain after a first knee replacement on one side. It focuses on people with clear signs of inflammation on ultrasound and checks follow-up outcomes after surgery.
London, OntarioAges 41–80 - NCT05823727Recruiting
Collagen supplement study before and after knee replacement
This study tests whether taking collagen peptides can improve how knee tissues heal and remodel after total knee arthroplasty (knee replacement). It also looks at functional recovery and wound healing, especially during the physical therapy period in Little Rock.
Little Rock, ArkansasAges 50–75 - NCT05892133Recruiting
Exercise program before knee replacement to improve recovery
This trial studies whether doing a structured exercise or “prehab” program before total knee replacement can improve knee function and patient satisfaction after surgery. It may help you recover better and feel more confident in your outcome.
Molde, Møre og RomsdalAges 50–80 - NCT05980442Recruiting
Navigation vs robotic-arm assisted knee replacement
This study compares two different high-tech tools used during total knee replacement surgery: one that uses a navigation system (OrthoPilot) and one that uses a robotic arm (MAKO). The goal is to see if one method leads to better results. If you're having a total knee replacement, this trial could help your surgeon choose the best approach.
Ulm, Baden-WurttembergAges 18–90 - NCT05981105Recruiting
Recovery and Chronic Pain After Knee Replacement
This study tests a special recovery program after knee replacement surgery to see if it helps reduce long-term pain. You may be eligible if you are having a first-time knee replacement for osteoarthritis, are between 18 and 65, and live near the hospital.
New York, New YorkAges 18–75 - NCT06040827Recruiting
Study of a knee implant extension for knee replacement
This trial is for adults having their first knee replacement surgery. It tests a special part (tibial extension) of a common knee implant system. Researchers will follow participants over time to see how well it works.
Fayetteville, ArkansasAges 18 years+ - NCT06083480RecruitingPhase 4
Reducing stress to prevent long-term pain after knee replacement
This trial tests if lowering oxidative stress (damage from natural body processes) during knee replacement surgery can prevent chronic pain afterward. It may help people with osteoarthritis who have moderate to severe pain before surgery.
Nashville, TennesseeAges 50 years+ - NCT06122727Recruiting
Custom vs standard knee replacement for better fit
This trial compares custom-made knee replacements (built to fit your unique knee shape) with standard, off-the-shelf knee replacements. It aims to see if a custom implant leads to better function and satisfaction after surgery.
BolognaAges 40–70 - NCT06123715RecruitingPhase 2
Vitamin C to reduce pain after knee replacement
This study tests whether taking vitamin C before and after knee replacement surgery can reduce long-term pain. You may be eligible if you are having knee replacement for osteoarthritis and are generally healthy.
