Recruiting studies
- NCT06880497Recruiting
Comparing knee sounds after two types of knee replacement
This study compares how much noise the knee makes (and how it feels to the patient) after two different kinds of total knee replacement surgery. It aims to help patients know what to expect after surgery.

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 - 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 - NCT06733597Recruiting
Bone density change after knee replacement with or without cement
This study looks at how bone density in the thigh bone changes after knee replacement surgery, comparing two ways of attaching the new joint (with cement or without). It may help people who have normal bone density or early bone thinning but not full osteoporosis.

Study on Hi-Fatigue G Bone Cement in Knee or Hip Replacement
This study looks at how well a specific bone cement (Hi-Fatigue G) works in people who have had a knee or hip replacement. It aims to help doctors understand if this cement is a good option for holding the artificial joint in place.
Weiden, BavariaAges 18 years+ - NCT06687109Recruiting
Joint replacement surgery registry study
This study collects information from people having joint replacement surgery to track how they do over time and improve care.
Spokane, WashingtonAges 18 years+ - 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 - NCT06634654Recruiting
AI-guided knee replacement study
This trial tests whether using artificial intelligence can improve recovery from total knee replacement by tailoring care to your body's needs. It may help people with severe knee arthritis who have not had major knee surgery before.
Rome, ItalyAges 18 years+ - NCT06643845Recruiting
Can medical treatments delay or avoid knee replacement?
This trial tests whether a combination of non-surgical treatments can help people with knee osteoarthritis avoid or delay total knee replacement surgery. It may be an option if you are considering knee replacement but want to explore medical alternatives first.
AmiensAges 18–90 - NCT06618820Enrolling by invitationPhase 3
Extended tranexamic acid after knee replacement
This trial tests whether taking tranexamic acid (a medicine that helps blood clot) for several days after knee replacement surgery reduces bleeding and improves recovery. It may help patients who have a standard knee replacement and are not on blood thinners.
Germantown, TennesseeAges 18 years+ - NCT06627673Recruiting
A new knee implant study for severe arthritis
This study compares a new plastic-and-metal knee implant to a standard metal one for people with severe knee arthritis. If you need a total knee replacement and your knee is not too bent or twisted, you may be a candidate.
Leawood, KansasAges 18 years+ - NCT06627699Recruiting
Study of the Freedom Total Knee System for knee replacement
This study is for people getting a total knee replacement for the first time. It looks at how well the Freedom Total Knee System works in everyday life.
Leawood, KansasAges 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+ - 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 - NCT06580899Enrolling by invitationPhase 4
Knee pain pump study for single knee replacement surgery
This study tests whether a small pain pump placed in your knee joint during surgery can help control pain after a single knee replacement. It is for people who are having outpatient knee replacement surgery and have not been taking strong pain medicines recently.
Charlotte, North CarolinaAges 18 years+ - NCT06565377Recruiting
Pre-surgery program for knee replacement patients
This trial tests a program of exercise, education, and support to help you prepare for knee replacement surgery. It aims to improve your recovery and quality of life.
Geel, AntwerpenAges 18 years+ - NCT06447922Enrolling by invitation
Metal Levels After Knee Replacement
This study measures metal levels in the blood after knee replacement surgery. It may help researchers understand how metal from the new joint affects the body.
Rochester, MinnesotaAges 18–100 - NCT06423716RecruitingPhase 4
Duloxetine to reduce opioid use after knee replacement
This study tests whether taking the pain medication duloxetine before and after knee replacement surgery can reduce the need for opioid painkillers. It may help patients manage pain with fewer side effects from strong narcotics.
Toronto, OntarioAges 50 years+ - NCT06389435Recruiting
Robotic versus conventional knee replacement surgery
This study compares two ways of performing total knee replacement surgery: one using a robotic assistant and the other using traditional techniques. The goal is to see if robotic-assisted surgery leads to better outcomes for patients.
HässleholmAges 18 years+ - NCT06264076Recruiting
