Recruiting studies
- NCT06321042Recruiting
Knee replacement study using sensor-guided implant placement
This study tests whether using small motion sensors during knee replacement surgery leads to better outcomes. It is for people aged 50–84 with severe knee pain from arthritis or bone damage who are scheduled for a first-time cemented total knee replacement.
Bologna, ItaliaAges 50–85 - NCT05992064Recruiting

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+ - NCT05831696Recruiting
Compare walking effort with two types of prosthetic knees
This trial studies how much energy it takes to walk when using passive versus powered prosthetic knees. It may help people understand which knee type could make walking feel easier depending on their needs.
Loma Linda, CaliforniaAges 18–75 - NCT05736549RecruitingPhase 2
Tested stronger pain-blocking shot for knee replacement surgery
This Phase 2 study compares two ways to reduce pain after total knee replacement (TKA): a steroid-enhanced nerve block versus a numbing shot called Exparel. It aims to see which option improves comfort and recovery after surgery done with spinal anesthesia.
New Haven, ConnecticutAges 18 years+ - NCT05314491Recruiting
Follow-up study after knee replacement with a specific implant
This study follows people after they get a total knee replacement using the Multigen Plus system, sometimes with special cone pieces. It looks at how well the implant performs over time and whether results meet expectations.
GuimarãesAges 18 years+ - NCT05516381Recruiting
Navigation-assisted knee replacement with two alignment methods
This study tests a computer-guided technique for total knee replacement and compares two ways of aligning the new joint. It may help improve how accurately the surgery is done, which could affect comfort and function afterward.
BarcelonaAges 18 years+ - NCT04884542Recruiting
Testing a knee replacement implant for total knee arthroplasty
This study looks at outcomes after surgery using the Multigen Plus H knee replacement system, sometimes with special add-on parts called AMF TT cones. It may help improve how well these knee implants work and how patients recover after total knee replacement.
GhentAges 18 years+ - NCT04716803Recruiting
BMAC injection for severe knee osteoarthritis before knee surgery
This trial studies injecting “bone marrow aspirate concentrate” (BMAC) into the knee to help relieve pain from severe knee osteoarthritis. It’s for people who have strong signs of advanced arthritis on X-ray and still have ongoing pain despite usual treatments, before a planned knee procedure.
La Jolla, CaliforniaAges 45–75 - NCT04924205Recruiting
Smart knee brace rehab versus usual physical therapy
This trial compares recovery after primary knee replacement using a smart knee brace and app versus standard outpatient physical therapy. It may help you understand which rehab approach leads to better comfort and mobility during recovery.
Iowa City, IowaAges 18–100 - NCT04752761Recruiting
Digital tracking after knee replacement for people with severe knee arthritis
This study checks whether using digital tools (like a phone app or tablet) can better track patient-reported outcomes after knee replacement, compared with usual outpatient follow-up. It may help improve how symptoms and recovery are monitored, which can guide care.
Bologna, ItaliaAges 18–78 - NCT04432012RecruitingPhase 4
Compare steroid shots versus other delivery after knee replacement
This study compares different ways of giving steroid medicine after a total knee replacement to see which approach works best and is well-tolerated. You may qualify if you’re getting a first (not repeat) knee implant and can follow the study steps.
LuganoAges 50–85 - NCT07158736Recruiting
Nerve block for knee pain in the emergency room
This trial tests whether a nerve block can reduce knee pain in the emergency room. If you have knee pain without an injury and are at least 18 years old, this treatment may offer quick relief.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07108920Recruiting
Balance and Botox for Stiff Knee Gait
This study tests whether botulinum toxin (Botox) injections into the rectus femoris thigh muscle can improve balance and walking in people with a stiff knee gait (a common problem after stroke, brain injury, or multiple sclerosis).
Héricourt, Nord Franche-ComtéAges 18 years+ - 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+ - NCT07155837Enrolling by invitation
TENS for pain after first knee replacement surgery
This study tests if a TENS device, which uses mild electrical pulses to relieve pain, helps people recover better after their first total knee replacement. It might reduce pain and improve movement.
Adana, AdanaAges 18 years+ - NCT07050277RecruitingPhase 3
Morphine for bladder issues after knee replacement
This study tests whether adding morphine to spinal anesthesia can reduce trouble urinating after a second knee replacement surgery. It may help you avoid needing a catheter after surgery.
Toronto, OntarioAges 21 years+ - NCT06108063RecruitingPhase 1/Phase 2
Losartan to prevent knee stiffness after replacement
This study tests whether losartan, a blood pressure medicine, can prevent excessive scar tissue (arthrofibrosis) after a total knee replacement. Participants receive losartan or a placebo for 6 months after surgery to see if it improves knee motion and reduces stiffness.
Vail, ColoradoAges 18 years+ - NCT07639424RecruitingPhase 4
New cartilage regeneration treatment for knee repair
This study tests a new platform to help repair damaged knee cartilage. If your knee has a specific type of cartilage damage, this treatment might help restore function and reduce pain.
Daegu, DaeguAges 19–64 - 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+ - NCT07204119Recruiting
Comparing two therapies for knee stiffness after fracture surgery
This trial tests two physical therapy techniques to help people regain knee movement after surgery for a broken leg bone. It may help if you are still having trouble bending or straightening your knee a few weeks after your operation.
Rawalpindi, Punjab ProvinceAges 20–40 - NCT07551245Recruiting
High-intensity laser vs traditional treatment for knee osteoarthritis
This study tests whether high-intensity laser therapy works better than traditional physical therapy methods for knee osteoarthritis pain and function. You'll be randomly assigned to receive either laser treatments or standard rehabilitation exercises.
Erbil, Erbil GovernorateAges 30–60 - NCT05279092RecruitingPhase 2
Testing two pain-control injections for knee replacement surgery
This Phase 2 study compares two ways of reducing nerve pain after knee replacement surgery (total knee arthroplasty). It looks at whether steroid-enhanced pain medicine works better than a different numbing injection to improve recovery and comfort.
New Haven, ConnecticutAges 18 years+ - NCT07542808RecruitingPhase 2/Phase 3
Stem cell treatment vs. hyaluronic acid for knee arthritis
This study tests whether an injection of stem cells (special cells that can help repair tissue) works better than a standard hyaluronic acid injection for knee osteoarthritis pain. Both treatments are injected into the knee to reduce pain and improve function.
Abu DhabiAges 18 years+ - NCT07409090Enrolling by invitation
Micro-Coring for loose skin on the knees
This trial tests a new, minimally invasive tool called Micro-Coring to tighten loose skin on the knees. It may be a good option if you have mild to moderate skin looseness on your knees and are looking for a non-surgical fix.
