Recruiting studies
- NCT06182059Recruiting
Pain after knee replacement study
This study looks at long-term pain after total knee replacement surgery. It may help understand why some people have persistent pain and find ways to prevent it.

Custom vs standard knee replacement for better fit
This trial compares custom-made knee replacements (built to fit your unique knee shape) with standard, off-the-shelf knee replacements. It aims to see if a custom implant leads to better function and satisfaction after surgery.
BolognaAges 40–70 - NCT06123715RecruitingPhase 2
Vitamin C to reduce pain after knee replacement
This study tests whether taking vitamin C before and after knee replacement surgery can reduce long-term pain. You may be eligible if you are having knee replacement for osteoarthritis and are generally healthy.
Toronto, OntarioAges 18 years+ - 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+ - NCT06038240Recruiting
Pain self-management program for knee replacement
This study is testing a program to help people manage pain on their own before and after total knee replacement surgery. It aims to improve recovery and reduce reliance on pain medications.
Charlottesville, VirginiaAges 18–85 - 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 - 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 - 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 - 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+ - NCT05288803Recruiting
Personalized rehab after knee replacement for veterans
This study tests a personalized rehabilitation program for veterans who have had a total knee replacement. It aims to improve recovery by tailoring therapy to each person's progress.
Aurora, ColoradoAges 40–90 - 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+ - 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 - 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+ - NCT04848896Recruiting
Safety and outcomes study of a smart knee replacement
This trial studies whether a “smart” knee replacement system (CORI) is safe and works well for people getting a total knee arthroplasty (TKA). If you’re a good candidate for a cemented standard knee replacement, the study follows you for two years to check results after surgery.
EppingAges 18 years+ - NCT05936814Recruiting
Study measures knee alignment in severe varus osteoarthritis
This study focuses on people age 65+ with severe “varus” knee alignment osteoarthritis (wear-and-tear arthritis that affects how the knee lines up). It aims to use your knee measurements and data to better understand the condition and guide care.
AnkaraAges 65 years+ - 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 - 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+ - NCT06383936Recruiting
Knee replacement for active sports lovers
This study tests a new knee replacement designed for active people ages 40 to 65 who used to play sports but had to stop due to knee pain. It aims to see if the implant helps you return to your favorite activities.
BolognaAges 40–65 - NCT07360392Recruiting
Nerve block comparison for knee replacement pain
This study compares two numbing techniques (nerve blocks) for pain relief after knee replacement surgery. The goal is to find which one works better and helps you recover with less pain.
AmasyaAges 18–80 - NCT03869996Recruiting
Fast-track recovery for knee replacement patients
This trial studies a faster recovery “fast-track” plan for people getting their first total knee replacement for arthritis. It may help by getting you back to movement and normal life sooner, while comparing outcomes against usual care.
BolognaAges 18–78 - NCT05302934Recruiting
Testing a knee-surgery app and sensor after knee replacement
This trial checks whether a data platform that uses a wearable sensor and a phone app works well for people getting a total knee replacement. It may help make follow-up care more organized and easier by capturing recovery information.
Konstanz, Baden-WurttembergAges 18 years+ - NCT07767097Recruiting
Low-dose radiation after revision knee replacement for stiffness
This study tests whether a single low dose of radiation after revision knee replacement surgery can help reduce stiffness and improve knee movement in people who had a stiff knee after their first replacement. The radiation is given along with usual care after surgery.
