Testing a new hip replacement system and how patients do
This study follows people getting a primary total hip replacement using the Entrada hip system to see how long it lasts and how well it works. You may be offered this specific hip implant and would be followed through study visits to measure recovery and outcomes.

This study compares two implant types used for a partial knee replacement (only the inside/medial part) for people with “wear-and-tear” arthritis in that compartment. It looks to see which option leads to better outcomes after surgery and follow-up.
LondonAges 40–80 - NCT07552415Recruiting
Joint Immobilization After Knee Replacement Revision Surgery
This study tests whether keeping your knee still for a period after revision knee replacement surgery helps improve how well you can bend and straighten it. Researchers want to see if immobilization (using a brace or cast) helps you regain better movement compared to standard care.
New York, New YorkAges 18 years+ - NCT07086716Recruiting
Frailty study for hip or knee replacement patients
This study looks at frailty in people who have had a planned hip or knee replacement. It aims to understand how frailty affects recovery.
Rovato, BSAges 18 years+ - NCT06971757Recruiting
Is yearly check-up after hip or knee replacement needed?
This study looks at whether routine check-ups one year after hip or knee replacement are helpful or unnecessary. If you've had or are scheduled for a first hip or knee replacement for arthritis, you may be able to join.
AmsterdamAges 50 years+ - NCT06699134Recruiting
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+ - NCT07840391Recruiting
Recovery after same-day knee replacement surgery
This study looks at how your physical activity, sleep, and knee function change after you go home the same day as your knee replacement surgery. It aims to help you recover better by understanding these factors.
TampereAges Up to 80 years - NCT07839403Recruiting
Comparing two types of hip replacement for arthritis
This study compares two types of hip replacement surgery: a newer option that preserves more bone (ceramic hip resurfacing) and a standard total hip replacement. Participants will wear a small activity monitor to see how their activity levels change after surgery, which may help doctors understand which procedure leads to a more active recovery.
DanderydAges 18 years+ - NCT07598552Recruiting
Brain Function Changes After Same-Day Hip or Knee Surgery
This study checks whether patients who have hip or knee replacement surgery and go home the same day experience any temporary changes in thinking or memory. Researchers want to understand how anesthesia and surgery affect the brain in the short term.
SvendborgAges 70 years+ - NCT07577869Recruiting
Nerve blocks for pain relief after knee replacement
This trial tests two types of numbing injections (nerve blocks) around the knee to help manage pain after total knee replacement surgery. The goal is to see if these injections reduce pain and improve recovery compared to standard pain treatment.
Kayseri, KocasinanAges 18–80 - NCT07551856Recruiting
Robotic vs. manual knee replacement surgery for arthritis
This study compares two ways to perform knee replacement surgery for osteoarthritis: traditional manual surgery versus robotic-assisted surgery. Both are standard approaches; the trial tests whether robotic guidance improves how well your knee works after surgery.
Glasgow, ScotlandAges 18 years+ - 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+ - NCT07347821Recruiting
Study of osteoarthritis in hip and knee replacement patients
This study looks at why osteoarthritis happens in the hip and knee by studying tissue samples taken during joint replacement surgery. If you are already scheduled for a first-time hip or knee replacement and have osteoarthritis, you may be able to join.
Ostrów Mazowiecka, Masovian VoivodeshipAges 18 years+ - NCT07226973Recruiting
Gait after hip replacement: comparing surgical approaches
This study compares how well people walk after three different types of hip replacement surgery for arthritis. It aims to see if one approach leads to a better walking pattern.
Metairie, LouisianaAges 18 years+ - NCT07110324Recruiting
Understanding long-term pain after hip or knee replacement
This study looks at people who still have moderate to severe pain months after a hip or knee replacement. The goal is to learn more about what causes this pain and how it feels, which could help improve future treatments.
Østerbro, København ØAges 18 years+ - NCT06991231Recruiting
Cryoablation benefits in knee replacement surgery
This trial tests if a special cold treatment (cryoablation) can help reduce pain or improve recovery for people getting knee replacement surgery for arthritis. It might offer an extra option to feel better after the procedure.
New York, New YorkAges 18 years+ - NCT06951477Recruiting
Gut health and knee replacement revision study
This study looks at how the bacteria in your gut might affect recovery after a second knee replacement surgery. Researchers want to learn more about the connection between gut health and surgical outcomes.
London, OntarioAges Any age - NCT06891807Recruiting
Robotic vs augmented reality knee replacement
This study compares two advanced technologies for total knee replacement: a robot that uses a CT scan for guidance versus an augmented reality system that uses no scan. The goal is to see which approach leads to better outcomes for patients with osteoarthritis.
Sint-Martens-Latem, Oost-VlaanderenAges 18–85 - NCT06787417RecruitingPhase 4
Knee alignment study for total knee replacement
This study compares two different surgical techniques for total knee replacement to see which one leads to better knee movement and function. If you need a knee replacement due to arthritis, this trial may help find the best approach for your surgery.
Hamilton, OntarioAges 18 years+ - NCT06676189Recruiting
Comparing two types of plastic knee implants for replacement
This study compares two different types of plastic knee implants (polyethylene) used in total knee replacement surgery. The goal is to see which one works best for patients with knee arthritis.
Clermont-FerrandAges 18–90 - 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+ - NCT06280352Recruiting
Robotic vs custom knee replacement trial
This study compares two modern ways of doing knee replacement: robot-assisted surgery versus a custom-made implant tailored to your knee shape. It aims to see which approach leads to better recovery and function for people with osteoarthritis.
Graz, StyriaAges 40–90 - NCT06264076Recruiting
Ligament balancing in knee replacement
This trial tests a new method of balancing the ligaments during total knee replacement. If you are generally healthy and need a first-time knee replacement due to arthritis, you may be eligible.
Bærums verk, AkershusAges 40 years+ - NCT05980442Recruiting
Navigation vs robotic-arm assisted knee replacement
This study compares two different high-tech tools used during total knee replacement surgery: one that uses a navigation system (OrthoPilot) and one that uses a robotic arm (MAKO). The goal is to see if one method leads to better results. If you're having a total knee replacement, this trial could help your surgeon choose the best approach.

- Yes. Clin2 currently lists 441 recruiting arthroplasty 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 arthroplasty 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 arthroplasty 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.
