Recruiting studies
- NCT06203756Enrolling by invitation
Robotic-Assisted Knee Replacement Outcomes Study
This study tests a robotic-assisted system for knee replacement surgery. It aims to see how well patients do with the robotic help.
Flagstaff, ArizonaAges Any age - NCT06083480RecruitingPhase 4
Reducing stress to prevent long-term pain after knee replacement
This trial tests if lowering oxidative stress (damage from natural body processes) during knee replacement surgery can prevent chronic pain afterward. It may help people with osteoarthritis who have moderate to severe pain before surgery.
Nashville, TennesseeAges 50 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.
Ulm, Baden-WurttembergAges 18–90 - NCT05876143Recruiting
Study of a knee implant with patient follow-up surveys
This trial follows people who already have (or are receiving) a specific partial knee implant to see how they do over time using questionnaires after surgery. It may help improve care for future patients with knee arthritis who get this type of implant.
Pierre-BéniteAges 18 years+ - NCT05290818Recruiting
Robotic vs standard knee replacement for inner-joint wear
This trial compares robotic-assisted knee replacement with the usual (non-robotic) approach for people with severe arthritis on the inner (medial) side of the knee. It aims to see which method works better for pain and function while matching the right knee anatomy for certain implant types.
Edinburgh, LothianAges 50–75 - NCT06127719Recruiting
Surgery wait time and knee replacement quality of life
This study looks at how waiting for knee replacement surgery affects your quality of life. It may help doctors understand how to improve care for people waiting for surgery.
Hoorn, North HollandAges 18–100 - NCT07727551Recruiting
Nerve block before knee replacement for better recovery
This trial tests if a nerve block given a few weeks before knee replacement surgery can improve pain and function after the operation. It is designed for people who have certain risk factors that might make recovery harder.
BrusselsAges 18–60 - NCT07730216Recruiting
Ultrasound-Guided Knee Block Study for Knee Replacement
This study looks at whether using ultrasound to guide a numbing injection around the knee can improve pain control after knee replacement surgery. It aims to make recovery more comfortable.
Konya, KonyaAges 18 years+ - NCT07672301RecruitingPhase 1/Phase 2
Comparing two anesthesia methods for knee replacement surgery
This trial compares total intravenous anesthesia (TIVA) with spinal anesthesia for people having a first-time total knee replacement who are expected to go home the same day. The goal is to see which method works better for recovery and comfort.
Chicago, IllinoisAges 18 years+ - NCT07601906Recruiting
Blood Flow Exercise Therapy After Knee Replacement Surgery
This study tests whether special exercises that temporarily reduce blood flow to your leg can help you recover better after knee replacement surgery. It focuses on reducing pain and improving your ability to bend and straighten your knee.
Lahore, Punjab ProvinceAges 50–65 - 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+ - NCT07539467Enrolling by invitation
Nerve Block and Tourniquet for Knee Surgery Pain Relief
This trial tests whether a nerve block (numbing injection near the thigh) combined with a tourniquet (pressure cuff) after knee replacement surgery reduces pain better than standard care. If it works, it could help patients recover more comfortably with less need for strong pain medications.
AnkaraAges 40–85 - NCT07477730Recruiting
Pain Relief Options for Knee Replacement Surgery
This study compares two ways to manage pain after knee replacement surgery: local numbing medicine injected into the knee versus numbing several nerves in the leg. The goal is to find which method provides better pain control and recovery.
Toulouse, Haute-GaronneAges 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+ - NCT07336160Recruiting
Nutrition before knee replacement surgery
This trial studies a special nutrition plan before knee replacement surgery to see if it helps recovery. Participants follow enhanced recovery guidelines for eating and drinking before their operation.
Istanbul, IstanbulAges 18 years+ - NCT05992064Recruiting
Wearable sensors to track recovery after knee replacement
This study uses a small wearable sensor placed on your leg after knee replacement surgery to track your recovery. It helps doctors see how well you are moving and healing, without extra visits to the hospital.
Frederikshavn, North DenmarkAges 18 years+ - NCT06947655Recruiting
Tourniquet types for knee replacement surgery
This study compares different types of tourniquets (tight cuffs) used during knee replacement surgery to see how they affect blood loss and how satisfied surgeons are with them.
Bonn, North Rhine-WestphaliaAges 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+ - NCT07053943Enrolling by invitation
Comparing single vs. multiple antibiotic doses for hip and knee replacement
This study compares two ways of giving antibiotics before hip or knee replacement surgery to see which one leads to fewer infections needing another surgery. It may help doctors choose the best antibiotic approach for patients having their first joint replacement.
Amsterdam, North HollandAges Any age - NCT07006545Enrolling by invitation
Getting back to activity after knee replacement
This study looks at how well people can return to daily activities and exercise after total knee replacement surgery. It may help find better ways to guide recovery.
Munich, BavariaAges 18 years+ - NCT06953375Recruiting
Electrical stimulation for faster recovery after knee replacement
This study tests if adding a gentle electrical stimulation (called NMES) to standard physical therapy helps people recover strength faster after knee replacement surgery. It is for patients who go to specific UCHealth or Intermountain Health therapy clinics after their first total knee replacement.
Aurora, ColoradoAges 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+ - NCT05097976RecruitingPhase 4
Medrol tablets to reduce pain after knee replacement
This trial tests whether a short course of Medrol (methylprednisolone) can improve recovery after outpatient total knee replacement done for osteoarthritis. You would be randomly assigned to receive Medrol or a comparison treatment.
Oak Brook, IllinoisAges 18 years+ - NCT06856356Recruiting

Common questions
- Are there clinical trials for knee arthroplasty?
- Yes. Clin2 currently lists 235 recruiting knee 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 knee 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 knee 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.
