Recruiting studies
- NCT04336579Recruiting
Breathing exercises during knee replacement care
This study tests whether practicing diaphragmatic (belly/chest-breathing) exercises during total knee replacement with a nerve pain catheter is helpful for comfort or recovery. You may qualify if you are having knee replacement and have the specific type of nerve catheter, and you’re willing to learn and follow the breathing routine.
Los Angeles, CaliforniaAges 50–90 - NCT04389749Recruiting
Continuous passive motion after certain hip or leg fractures
This trial studies whether a device that gently moves your leg helps recovery after surgery for specific hip or knee fractures. It may help with healing and getting you back to moving more comfortably sooner, compared with not using the device.
Cincinnati, OhioAges 18 years+ - NCT04427709RecruitingPhase 2
Testing a brain-activity measure using oxytocin and eye movements
This study tests whether a particular brain-activity signal—seen in small rhythmic eye movements—can be measured reliably. It also looks at how oxytocin (a hormone used in medical settings) affects that signal.
Winston-Salem, North CarolinaAges 18–75 - NCT04433572RecruitingPhase 3
Temsirolimus treatment to improve below-knee artery procedures
This trial studies whether delivering a medicine called temsirolimus directly into the artery during a below-knee revascularization procedure can improve blood flow and outcomes. It may help people with severe leg artery disease who have symptoms like pain while walking or threatened limb tissue loss.
Houma, LouisianaAges 18 years+ - NCT04511247Recruiting
Drug-coated balloon for artery disease below the knee
This trial tests a drug-coated balloon to open narrowed or blocked arteries in the lower leg (below the knee) and help them stay open. It’s meant for people with significant symptoms, to reduce re-narrowing after treatment.
SingaporeAges 21 years+ - NCT04554212Recruiting
Blood flow restriction therapy after kneecap instability
This trial tests whether a special exercise method called blood flow restriction training can help people recover faster and get back to running and pivoting activities after a kneecap (patella) that slips out of place. It may help strengthen the knee while you go through physical therapy.
Lexington, KentuckyAges 14–40 - NCT04576078RecruitingPhase 2
Nefopam for less pain after knee replacement surgery
This Phase 2 study tests whether oral nefopam can reduce pain after total knee replacement done with spinal anesthesia. It looks at whether this medicine works better than the usual post-surgery pain plan and how safely it can be used.
Lyon, LyonAges 18–75 - NCT04607174Recruiting
Test knee muscle activation in people with nerve or movement disorders
This study checks how well your knee muscles “turn on” during guided, controlled knee movements. It may help researchers understand movement problems and improve testing or therapies for neuromotor (nerve/movement) disorders.
Milan, MIAges 18–70 - NCT04607538Recruiting
Study of knee joint shape and patella dislocations in Faroese teens
This study looks at how knee joint shape differences may relate to repeated kneecap (patella) instability or near-dislocation, and what that means long-term. It specifically includes teens from the Faroe Islands and asks about symptoms and knee function over time.
HvidovreAges 15–20 - NCT04635436Recruiting
Split-walking training for one-sided leg weakness when walking hurts
This trial tests whether a “split gait” walking training method can improve walking balance and how you move when you have one-sided leg problems and pain or limitations when walking. It may help reduce walking difficulties by training your stepping pattern safely.
Milan, MIAges 18–70 - NCT04875052Recruiting
Study vibration after ACL injury and future arthritis risk
This study looks at whether using vibration after an ACL injury helps predict or reduce the risk of developing post-traumatic osteoarthritis (wear-and-tear arthritis) later. It may help researchers learn which patients are more likely to develop arthritis after ACL reconstruction.
Chapel Hill, North CarolinaAges 16–35 - NCT04912323Recruiting
Drug dissolving stent for blocked below-knee arteries
This trial studies a drug-eluting dissolving scaffold placed in blocked arteries below the knee to improve blood flow. It may help people whose leg circulation problems are severe enough to limit walking or threaten the limb, but only if their blockages fit specific imaging and procedure requirements.
GrazAges 18–90 - NCT02604563Recruiting
Aging, blood changes, and health in older adults
This study examines why some older adults develop changes in their blood cells that may affect their health. Researchers will look for links between these blood changes, aging, and common health problems in older people.
St Louis, MissouriAges 50 years+ - NCT07015905RecruitingPhase 3
Study of REGN7508 vs. standard blood thinners after knee replacement
This trial compares a new blood thinner called REGN7508 to two standard blood thinners (apixaban and enoxaparin) to prevent blood clots after total knee replacement surgery. The goal is to see which is safer and more effective.
Sheffield, AlabamaAges 18 years+ - NCT05073263Recruiting
Full versus partial weight bearing after FCL ligament repair
This study compares two rehab plans: doing full weight bearing versus partial weight bearing during the first 6 weeks after fibular collateral ligament (FCL) reconstruction. It may help figure out which approach is safer and better for healing and recovery.
Edina, MinnesotaAges 14–59 - NCT05124652Recruiting
Testing a prosthetic socket that adjusts automatically
This trial is testing a prosthetic socket that can automatically adjust to help fit better and feel more comfortable. It may help people with below-knee (transtibial) amputations who currently struggle with socket fit or comfort.
Seattle, WashingtonAges 18 years+ - NCT05211986RecruitingPhase 1/Phase 2
Test injection safety for knee osteoarthritis muscle weakness
This Phase 1/2 trial studies whether an injection called IMM01-STEM is safe and well-tolerated for people with knee osteoarthritis who also have muscle weakness. It also looks at whether the treatment could help in this group, while carefully monitoring side effects.
Irvine, CaliforniaAges 50–75 - NCT05323474Recruiting
Rehab program after ACL surgery to return to competitive sport
This study tests an “optimized” rehabilitation plan after ACL reconstruction to help people safely return to competitive sports. It’s for people who had an ACL surgery and still want to play sports that involve cutting, pivoting, or contact.
Challes-les-EauxAges 18–25 - NCT05344001Recruiting
Study links past sports injuries and low activity to later health
This study looks at how an earlier sports injury and time spent being inactive may relate to later health problems. It mainly needs specific age groups and either current/former collegiate athletes or non-athlete comparison participants.
Milwaukee, WisconsinAges 18–64 - NCT05381818Recruiting
Breathing muscle training before joint surgery
This trial tests whether strengthening breathing muscles before total joint surgery can lower the chance of lung complications after the operation. It may help people who already have breathing problems or a history of smoking.
Jacksonville, FloridaAges 18–100 - NCT05389410Recruiting
PICO dressings compared during repeat hip or knee surgery
This study compares two types of wound dressings (PICO 7 vs PICO 14) in people having a repeat (revision) hip or knee operation. It aims to see which dressing works better to help the surgical wound heal after surgery.
Oswestry, ShropshireAges 18 years+ - NCT05425810Recruiting
