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+ - NCT04901273Recruiting
PRP shot vs placebo for knee osteoarthritis in adults 65+
This trial compares an injection made from your own platelets (PRP) to a placebo shot to see if it helps knee osteoarthritis symptoms and function. It is designed for people over 65 with arthritis affecting only one knee.
BolognaAges 65 years+ - NCT07640516Recruiting
Pain Relief Comparison for Amputation Surgery in High-Risk Patients
This study compares two medications (dexmedetomidine and fentanyl) mixed with a numbing agent to see which works better for blocking pain during above-knee amputation surgery in patients with serious heart or lung disease. Both drugs are already used in anesthesia, and this trial tests which combination is safest and most effective for you.
CairoAges 18 years+ - NCT04960098Recruiting
Survey after hip or knee replacement surgery
This study asks people who have had a hip or knee replacement to share how they’re doing over time. It’s testing whether patient-reported survey answers can help measure recovery and outcomes.
MilanAges 18 years+ - NCT04998188Recruiting
Hydrolyzed collagen for one knee with osteoarthritis
This trial tests whether a hydrolyzed collagen drink or supplement can reduce knee pain and symptoms compared with a placebo (inactive treatment) in people with osteoarthritis. It may help if you’ve tried standard non-surgical treatments and still have ongoing knee trouble.
BolognaAges 18–75 - NCT05039463Recruiting
Platelet-Rich Plasma and Hyaluronic Acid for Knee Arthritis
This trial tests whether combining two types of injections—platelet-rich plasma (a concentration of healing cells from your own blood) and hyaluronic acid (a natural lubricant)—can reduce knee osteoarthritis pain and improve function over one year. You're eligible if you've already received or are about to receive these injections at Amiens University Hospital.
AmiensAges 18 years+ - NCT05073276Recruiting
Controlled weight-bearing after PCL or MCL knee ligament repair
This trial tests a specific, step-by-step approach to how much weight you put on your healing knee after surgery for certain ligament injuries (like PCL and/or MCL, and some combined cases). It may help you heal safely and recover function without putting too much strain on the repair.
Edina, MinnesotaAges 14–59 - NCT05100966Recruiting
Exercise program for people waiting for hip or knee replacement
This trial tests a “getting fit” program to help people who are somewhat frail before hip or knee replacement surgery. It aims to improve fitness while you wait for surgery, which may help you feel stronger for recovery.
Calgary, AlbertaAges 60 years+ - NCT05314608Recruiting
Testing IOBP treatment for knee bone lesions seen on MRI
This trial studies whether an IOBP® procedure can reduce knee pain in adults with a specific bone lesion under the joint surface. It focuses on people whose MRI shows one target lesion and who are already planned for IOBP surgery.
Denver, ColoradoAges 18–60 - NCT05332288Recruiting
Observing treatment outcomes for a knee cartilage defect
This observational study follows people with a specific knee cartilage injury from osteochondritis dissecans (OCD) to see how they do after standard care and rehab. It may help doctors understand which patients benefit most and what changes happen over follow-up.
BolognaAges 15–40 - NCT05378815Recruiting
Platelet injections for knee arthritis pain
This study tests whether platelet-rich plasma (a treatment made from your own blood) can reduce symptoms of knee osteoarthritis. It focuses on people with specific types of knee pain and X-ray findings, and compares against rules around current pain medicines and injections.
Créteil, Val-De-MarneAges 40–79 - NCT05423587Recruiting
Knee artery procedure for long-lasting knee arthritis pain
This study looks at whether blocking small blood vessels in the knee (genicular artery embolisation) can reduce pain from knee osteoarthritis when other non-surgical treatments haven't helped. It also checks safety and whether people can tolerate the imaging tests needed for the procedure.
ReadingAges 45 years+ - NCT05437562Recruiting
Trial compares recovery after lower-leg amputation in Veterans
This trial looks at outcomes after a below-knee (lower-leg) amputation in Veterans. It focuses on people who have blood flow likely to heal and who plan to join rehabilitation to walk again with a prosthesis.
Decatur, GeorgiaAges Any age - NCT05487053Recruiting
Nerve block type test after knee replacement
This study compares two pain-control methods for the leg after a total knee replacement: a single injection versus a continuous nerve-block catheter. It aims to see which option helps people recover and do rehab better.
MoscowAges 18 years+ - NCT05495334Recruiting
Add knee osteoarthritis outcomes to a patient registry
This study tests a new way to collect how people with knee osteoarthritis feel and function after usual care (like injections, nerve-blocking procedures, or knee replacement). It may help improve future treatment decisions by using your regular follow-up reports in an app or online.
Phoenix, ArizonaAges Any age - NCT05543941Recruiting
Test advanced irrigation during knee, hip, or shoulder replacement
This trial studies a cleaning solution used during surgery to lower the risk of complications and improve outcomes after joint replacement. It may be an option if you’re having a planned knee, hip, or humerus (shoulder) replacement and meet the specific health and allergy requirements.
Vancouver, British ColumbiaAges 18 years+ - NCT05559463Recruiting
