Recruiting studies
- NCT07449442Recruiting
Pain relief study after knee replacement surgery

Guangzhou, GuangdongAges 45–90 - NCT06423716RecruitingPhase 4
Duloxetine to reduce opioid use after knee replacement
This study tests whether taking the pain medication duloxetine before and after knee replacement surgery can reduce the need for opioid painkillers. It may help patients manage pain with fewer side effects from strong narcotics.
Toronto, OntarioAges 50 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+ - NCT07509866Recruiting
Comparing pain relief options for knee replacement surgery
This trial tests two different numbing medicines for knee replacement surgery. It compares a long-acting numbing medicine (liposomal bupivacaine) with a standard one (ropivacaine) mixed with other drugs to see which provides better pain control. The goal is to find a way to reduce pain and improve recovery.
Wuhan, HubeiAges 18–80 - NCT07356323Recruiting
Study on antibacterial drape for hip or knee replacement
This trial tests if a special antibacterial drape reduces contamination during hip or knee replacement surgery. The drape is placed over the skin to help prevent infection.
Fishers, IndianaAges 22 years+ - NCT07017400Recruiting
Nerve block for knee replacement pain relief
This trial tests a nerve block called the sacral erector spinae plane block to see if it improves pain control after total knee replacement surgery. If you're having a knee replacement and staying in the hospital overnight, you may be able to join.
CrotoneAges 18 years+ - NCT03519269Recruiting
Robotic versus standard knee replacement for severe knee arthritis
This study compares a robotic-assisted knee replacement to a standard (non-robotic) knee replacement. It may help people with severe knee arthritis learn which approach improves pain and knee function after surgery.
New York, New YorkAges 40–85 - 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 - NCT05823727Recruiting
Collagen supplement study before and after knee replacement
This study tests whether taking collagen peptides can improve how knee tissues heal and remodel after total knee arthroplasty (knee replacement). It also looks at functional recovery and wound healing, especially during the physical therapy period in Little Rock.
Little Rock, ArkansasAges 50–75 - NCT05892133Recruiting
Exercise program before knee replacement to improve recovery
This trial studies whether doing a structured exercise or “prehab” program before total knee replacement can improve knee function and patient satisfaction after surgery. It may help you recover better and feel more confident in your outcome.
Molde, Møre og RomsdalAges 50–80 - NCT07694895Recruiting
AI-assisted education for knee replacement recovery
This trial tests if an AI-powered educational video before you get up and walk after knee replacement surgery can help reduce fear of movement and make you feel more ready to leave the hospital.
Kocaeli, İzmitAges 18–100 - NCT06557018RecruitingPhase 4
Numbing medicine injection for knee replacement pain
This study tests a long-lasting numbing medicine (liposomal bupivacaine) injected around the knee during total knee replacement surgery. It aims to see if this medicine helps control pain and reduce the need for other painkillers after surgery.
Dezhou, ShandongAges 18–80 - NCT07439575Recruiting
Wound closure methods in hip and knee replacement
This study compares different ways of closing the wound after hip or knee replacement surgery. It looks at which methods heal best with fewer problems.
Istanbul, IstanbulAges 30 years+ - NCT05616884Enrolling by invitation
Cemented vs cementless partial knee replacement study
This study compares two ways of fixing a partial knee replacement: cemented or cementless. It may help doctors learn which method works better for patients with certain types of knee bone.
Alexandria, VirginiaAges 18–85 - NCT06389435Recruiting
Robotic vs. conventional knee replacement study
This trial compares robotic-assisted knee replacement surgery to the standard, conventional method. It aims to see if the robotic technique leads to better outcomes for patients getting a total knee replacement.
StockholmAges 18 years+ - NCT04247672Recruiting
Study of knee replacement outcomes using a specific knee implant
This study follows people who need knee replacement for “end-stage” knee osteoarthritis and will receive a specific knee implant system as part of routine care. It aims to measure how well the knee replacement works for patients over time, which may help improve future care.
Hoofddorp, North HollandAges 21–90 - NCT07286513Enrolling by invitation
Study of a new knee replacement implant
This study follows patients who receive a specific type of knee replacement implant called the Persona® SoluTion® PPS, to see how well it works over time. If your surgeon recommends this implant and you meet standard health requirements, you may be able to join.
Denver, ColoradoAges 18 years+ - NCT06758297Recruiting
AI motivational talk after knee replacement
This study tests whether an artificial intelligence-guided motivational conversation can help reduce fear of moving after knee replacement surgery, and improve how much you can move.
Samsun, SamsunAges 18 years+ - 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+ - 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+ - NCT06120023Recruiting
Long-term follow-up of the Madison knee replacement system
This study follows patients in France who receive a Madison total knee replacement. It watches how well the knee works and how the patient feels over time, to make sure the implant is safe and effective.
Lyon, RhôneAges 18 years+ - NCT07020312RecruitingPhase 2
Brain training to improve muscle recovery after joint surgery
This trial tests whether brain-computer interface training can help you regain muscle control more effectively after knee or hip surgery. It focuses on four common procedures and uses neurofeedback to optimize muscle activation during recovery.
Chicago, IllinoisAges 18 years+ - NCT07526831Recruiting
Pain Relief Methods for Knee Surgery: Two Nerve Block Approaches
This study compares two ways of numbing nerves around the knee during surgery to see which method reduces pain better after the operation. Both methods use safe, well-established pain-relief techniques.
