New York, New YorkAges 40–75 - NCT03484325Enrolling by invitation
Patient registry for joint replacement and related surgeries
This trial is a “registry,” meaning it collects information from people who choose certain elective joint surgeries. It may help doctors better understand outcomes and safety after procedures like hip and knee operations.
Houston, TexasAges 18–100 - NCT07425457Recruiting
Cold nerve treatment before knee replacement surgery
This trial tests a cold therapy on nerves before knee replacement to reduce pain. It may help you recover with less discomfort after surgery.
AthensAges 18 years+ - NCT06251752Recruiting
Long-term study of kneecap after knee realignment surgery
This study looks at how well the kneecap joint holds up many years after a knee realignment surgery (high tibial osteotomy) for inner knee arthritis. If you had this surgery more than 5 years ago, you may be able to join a long-term checkup that uses X-rays and medical records to see how your knee is doing.
BolognaAges 18–65 - NCT07589127Recruiting
Nerve Block for Pain Relief During Knee Replacement
This study tests whether blocking a specific nerve in the knee can reduce pain and improve recovery after total knee replacement surgery. You would receive this nerve block alongside standard anesthesia to see if it helps you need fewer pain medications afterward.
Hjelset, Møre og RomsdalAges 18–80 - NCT07324746Recruiting
Herbal supplement for osteoarthritis pain
This trial tests whether a herbal supplement helps people with osteoarthritis of the knee or hip feel less pain and move better. If you have moderate to severe pain and are able to walk, this study might be a good fit.
LondonAges 18 years+ - NCT07721116Recruiting
AI Study of Knee Imaging and Treatment Results
This study uses artificial intelligence (AI) to better understand knee images from healthy people and those with knee arthritis. It aims to predict how well knee injections might work for you.
Taipei, TaiwanAges 18 years+ - NCT06893302Recruiting
Bone marrow injection during knee scope for cartilage or meniscus
This trial tests if adding a bone marrow injection to standard knee arthroscopy helps your knee heal better. It is for people with a torn meniscus or damaged cartilage who have healthy knee joints without arthritis.
New York, New YorkAges 18–64 - NCT07767409Recruiting
Home exercise app versus clinic physiotherapy for knee arthritis
This study compares doing exercises and self-care through a smartphone app to attending physiotherapy at a hospital clinic for people with knee osteoarthritis. It aims to see if the app is as helpful for reducing pain and improving function.
SingaporeAges 45–95 - NCT07701174Recruiting
Weighted exercise vs muscle stimulation for knee arthritis
This study compares two treatments for knee osteoarthritis: weighted dangling exercises and neuromuscular electrical stimulation of the knee muscle. It aims to see which one reduces pain and improves function better.
Lahore, Punjab ProvinceAges 40–60 - NCT06080347Recruiting
Anti-inflammatory diet for knee osteoarthritis
This study tests whether an anti-inflammatory diet can help with knee osteoarthritis. If you have OA in one knee and are open to changing your eating habits, you may be able to join.
San Diego, CaliforniaAges 18 years+ - NCT07481461Recruiting
Knee alignment and biology in osteoarthritis
This study looks at how changes in knee alignment affect symptoms and joint biology in people with early knee osteoarthritis. It may help doctors understand how to better treat knee OA.
Leuven, Vlaams-BrabantAges 18 years+ - 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+ - NCT07367789Recruiting
Predicting recovery after knee replacement using smart insoles
This study uses special insoles to measure how you walk before and after a knee replacement. The goal is to see if these measurements can help predict how well you will recover after surgery.
Yongin-si, Gyeonggi-doAges 19 years+ - NCT07313020Enrolling by invitationEarly Phase 1
Handheld imaging to track stem cells in knee osteoarthritis
This trial tests a new handheld imaging device (MPI) to track stem cells injected into the knee. It aims to see if the device can safely monitor how the stem cells move and work in people with knee osteoarthritis.
Haikou, HainanAges 18–75 - 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 - 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+ - NCT06490770Recruiting
Understanding knee pain and function
This study looks at how your knee joint works when you have pain or limited function. It uses MRI and electrical stimulation to learn more about cartilage and meniscus damage, which might help improve future treatments.
BolognaAges 18–60 - NCT06187038Recruiting
Pain education study for knee osteoarthritis
This trial tests if learning about chronic pain can help people with knee osteoarthritis feel better. You'll join a program that teaches you about pain and how to manage it.
São PauloAges 40–80 - 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 - NCT03383081RecruitingPhase 2
Stem cell injection for moderate knee osteoarthritis pain

Common questions
- Are there clinical trials for knee osteoarthritis?
- Yes. Clin2 currently lists 390 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.
