Recruiting studies in California
- NCT05495334Recruiting
Add knee osteoarthritis outcomes to a patient registry
This study tests a new way to collect how people with knee osteoarthritis feel and function after usual care (like injections, nerve-blocking procedures, or knee replacement). It may help improve future treatment decisions by using your regular follow-up reports in an app or online.
Irvine, CaliforniaAges Any age - 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.
El Cajon, CaliforniaAges 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.
Huntington Beach, CaliforniaAges 18 years+ - 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.
Fountain Valley, CaliforniaAges 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 - 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 - NCT05986292RecruitingPhase 2
Study of new treatments for chronic pain
This study tests new treatments for chronic pain that lasts at least 3 months. Participants must stop their regular pain medicines and use only a rescue painkiller if needed. The goal is to find better ways to manage long-term pain.
Irvine, CaliforniaAges 18 years+ - NCT04816773Enrolling by invitation
Long-term follow-up for specific knee replacement parts
This study follows people for up to 10 years after a knee replacement done with specific manufacturer parts. It helps the company and doctors understand how well these knee implants work and whether they cause any long-term problems.

What taking part in a knee osteoarthritis study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there knee osteoarthritis clinical trials in California?
- Yes. We're currently tracking 32 recruiting knee osteoarthritis studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a knee osteoarthritis study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a knee osteoarthritis trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
