Recruiting studies
- NCT07151417RecruitingPhase 2/Phase 3

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+ - NCT07339111RecruitingPhase 3
CARTISTEM vs surgery for knee cartilage damage and osteoarthritis
This trial tests if a cell-based treatment called CARTISTEM can repair knee cartilage better than surgery alone. It involves people with knee osteoarthritis and a cartilage defect, with moderate pain and limited function.
Birmingham, AlabamaAges 18–75 - NCT07153471RecruitingPhase 3
A study of an experimental pill for weight loss and knee arthritis
This trial tests an investigational medication (orforglipron) to see if it helps people with knee arthritis lose weight. You may qualify if you have overweight or obesity and have tried dieting before without lasting success.
Phoenix, ArizonaAges 18 years+ - NCT04318041RecruitingPhase 3
Diacerein to improve knee osteoarthritis symptoms
This Phase 3 study tests diacerein (Artrodar®) to see if it can improve symptoms in people with knee osteoarthritis, and it uses movement and scan-based assessments. It may help reduce walking pain and improve knee function for the right patient group.
Bangkoknoi, BangkokAges 40–65 - 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 - NCT05946044Recruiting
Preventing Knee Arthritis in People at Higher Risk
This study looks at ways to help prevent knee osteoarthritis before it starts. It is designed for women with higher body weight who currently have no arthritis signs on scans and do not have much knee pain.
Boston, MassachusettsAges 50 years+ - NCT06188806Recruiting
Nerve block location study for knee replacement pain
This study compares two types of nerve blocks (proximal vs. distal adductor canal block) for pain relief after knee replacement surgery. The goal is to see which approach provides better pain control and recovery.
Istanbul, UmraniyeAges 18–85 - 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 - NCT07775248RecruitingPhase 4
Long-lasting pain relief after knee replacement
This trial tests a new type of pain medicine that is given during knee replacement surgery and slowly releases pain relief over several days. It may help reduce the need for opioid painkillers after surgery.
Grosse Pointe Farms, MichiganAges 18 years+ - NCT07673328Recruiting
Knee brace study for people with knee arthritis
This study tests a motorized knee brace for people with knee osteoarthritis. The brace helps support your knee as you walk, climb stairs, and go up and down ramps.
Ann Arbor, MichiganAges 18–85 - NCT07219888Enrolling by invitationPhase 4
Comparing suzetrigine and oxycodone for knee replacement pain
This study compares a new pain medicine called suzetrigine with a commonly used opioid, oxycodone, for pain after a knee replacement. The goal is to see which works better and has fewer side effects.
Louisville, KentuckyAges 21–89 - NCT06488144RecruitingPhase 3
Knee arthritis rehab: helping veterans keep improving
This study tests a program that helps veterans with knee osteoarthritis keep up the gains they make in physical therapy. It uses a Fitbit and a smartphone app to support you and track your activity after your PT sessions end.
Birmingham, AlabamaAges 40–90 - NCT06686680Recruiting
Shockwave therapy for knee arthritis after ACL repair
This study tests whether shockwave therapy can help knee pain and function in people who developed knee osteoarthritis after an ACL reconstruction. If you had ACL surgery at least a year ago and still have knee pain, this treatment might offer a new option without surgery.
Cambridge, MassachusettsAges 18–55 - NCT07397806Recruiting
Home-based leg trainer for knee osteoarthritis
This study tests a home exercise device designed to improve leg control and reduce pain in people with knee osteoarthritis. You may be eligible if you have knee pain and are between 40 and 85 years old.
Vail, ColoradoAges 40–85 - NCT05507099RecruitingPhase 2
Stem cell injections for knee or hip osteoarthritis pain
This Phase 2 study tests whether stem cell injections can reduce pain and improve symptoms in people with knee or hip osteoarthritis. You may be considered if you have moderate-to-severe pain despite trying standard treatments.
Brampton, OntarioAges 18–95 - NCT06833749RecruitingPhase 2
Testing KBP-336 for knee osteoarthritis with obesity
This study tests an experimental medicine called KBP-336 for people with both obesity and knee osteoarthritis who still have significant knee pain despite standard treatments. It aims to see if KBP-336 can reduce pain and improve function.
BrnoAges 45 years+ - NCT06514755Recruiting
Nerve block before artery treatment for knee pain
This study tests a two-step procedure for long-term knee pain that hasn't improved with other treatments. First, the nerves around the knee are numbed, and then the small arteries feeding the painful area are blocked. The goal is to see if doing the nerve treatment before the artery treatment works better for reducing pain.
ZagazigAges 18–80 - NCT07353931RecruitingPhase 3
Study of eloralintide for knee osteoarthritis pain in people with overweight or obesity
This trial tests an investigational drug called eloralintide to see if it can reduce knee pain in people with osteoarthritis who also have overweight or obesity. You may be able to join if you have knee osteoarthritis, a BMI of 27 or higher, and have tried to lose weight with diet before.
Mobile, AlabamaAges 18 years+ - NCT06514365Recruiting
Comparing nerve blocks for pain after knee replacement
This trial compares two different ways of numbing the leg to provide better pain relief after total knee replacement surgery. It tests whether adding a popliteal sciatic nerve block (behind the knee) to a saphenous block (inner thigh) works better than adding an IPACK block (back of the knee).
Badalona, BarcelonaAges 18 years+ - NCT06906939RecruitingEarly Phase 1
Brain stimulation and tai chi for knee arthritis and depression
This pilot study tests if combining brain stimulation (rTMS) with Tai Chi can help knee arthritis pain and improve depression. It compares these two treatments to see which works better for people with both pain and low mood.
Los Angeles, CaliforniaAges 50–95 - NCT07367126Recruiting

Common questions
- Are there clinical trials for knee osteoarthritis?
- Yes. Clin2 currently lists 408 recruiting knee osteoarthritis studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a knee osteoarthritis trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a knee osteoarthritis trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
