This study tests whether a wearable bioimpedance wristband (like a fitness tracker) helps people with severe obesity and knee osteoarthritis improve their body composition—gaining muscle and losing fat—before joint replacement surgery. All participants receive coaching on body co…

This study tested an experimental drug called LNA043, given as injections into the knee, to see if it could slow cartilage loss and reduce pain in people with knee osteoarthritis. The trial planned to follow 576 participants for up to 5 years, but it was terminated early. The mai…

This study tested a drug called lorecivivint, given as a knee injection, to see if it could safely slow knee osteoarthritis and improve pain and function over two years. It enrolled 276 people who had already completed an earlier study. The trial was terminated early, so the full…

This small, early-phase study tested a single injection of lorecivivint into the knee joint of 13 people with moderate-to-severe knee osteoarthritis. The goal was to see if the drug could slow cartilage loss, measured by MRI scans. The trial was terminated early, so the results a…

This early study tested whether a single infusion of zoledronic acid, a drug used for osteoporosis, could improve bone health and slow joint damage after an ACL tear. Only 4 people were enrolled before the trial was terminated, so the results are very limited. The study aimed to …

This study tested whether injecting a person's own fat-derived stem cells into arthritic joints could safely reduce pain and improve movement. Only 14 people with osteoarthritis of the knee, hip, ankle, shoulder, or wrist took part before the study was stopped early. The results …

This study looked at how well a custom knee replacement system worked for people with knee osteoarthritis. Researchers tracked complications in 52 adults who had the surgery. The study was stopped early, so results are limited.

This study aimed to see if bariatric surgery or medical weight loss (diet and exercise) helps severely obese patients lose enough weight to safely undergo hip or knee replacement. Only 3 people took part before the study was stopped early. The goal was to get patients to a BMI of…

This study looked at how well the P.F.C. Sigma knee replacement implant works in people with severe knee arthritis. Researchers planned to follow 723 patients for at least 5 years after surgery, tracking pain, function, and any complications. However, the study was terminated ear…

This study tested whether special treadmill training before knee replacement surgery could help prevent falls afterward. Participants practiced recovering from trips or pushes on a treadmill. The trial was stopped early and only enrolled 5 people, so it is not clear if the traini…

This study looked at whether adding an iPACK nerve block to standard pain treatments (adductor canal block and local injections) helps people feel less pain and recover faster after total knee replacement. Only 10 people were enrolled before the study was stopped early. The goal …

This study looked at whether a drug called ZYNRELEF can control pain and reduce the need for strong opioid painkillers after knee replacement surgery. It included 29 adults aged 35-70 with knee osteoarthritis. The study was terminated early, so results are limited.

This study tested an investigational drug called QUC398 in 101 people with painful knee osteoarthritis. Participants received either QUC398 injections or a placebo. The goal was to see if the drug could reduce knee pain and improve cartilage health. The trial was terminated early…

This study tested an injection called lorecivivint for people with knee osteoarthritis. The goal was to see if it safely reduces pain and improves knee function over three years. The study was stopped early and included 72 adults aged 40 to 80.

This study tested whether a digital home exercise program (SimpleTherapy) could work as well as standard in-person physical therapy for people with chronic knee osteoarthritis pain. The plan was to have 32 adults with knee pain do exercises at home three times a week for six week…

This study compares a new minimally invasive procedure called genicular artery embolization (GAE) to standard steroid injections for reducing knee pain from osteoarthritis. It was designed for adults over 40 whose knee pain hasn't improved with other treatments. The goal is to se…

This study tested an experimental drug called GSK3858279 in 314 adults with moderate to severe knee osteoarthritis pain. The goal was to find the best dose that reduces pain safely. However, the trial was stopped early, so we have less information than planned.

This study tested a temporary peripheral nerve stimulation system (SPRINT PNS) placed near the knee for up to 60 days to relieve chronic pain from osteoarthritis. Only 12 people were enrolled, and the trial was terminated early. Researchers measured pain intensity, quality of lif…

This study tested two injected drugs, canakinumab and LNA043, for people with painful knee osteoarthritis. It aimed to see if they could reduce pain and improve cartilage. The trial was stopped early and included only 23 participants, so results are limited.

This study tested whether teaching people recovering from ACL reconstruction to run with a forefoot strike and a faster step rate could reduce knee pain and improve function. Ten active-duty soldiers and cadets participated. The approach is non-invasive and focuses on retraining …

This study tested a custom knee orthosis (brace) in people with medial knee osteoarthritis. Participants wore the brace for 8 weeks and completed a questionnaire about pain, stiffness, and function. The study was terminated early and only enrolled 2 people, so no firm conclusions…

This study looked at whether people with nickel allergy do better with special nickel-free knee implants. Researchers compared standard implants to nickel-free ones in 9 patients with self-reported nickel sensitivity. The goal was to see if nickel allergy affects pain, function, …

This study aimed to see if using a patient's healthy knee as a guide for aligning a new knee joint during replacement surgery leads to better results than the standard method. Researchers planned to compare two groups of people with arthritis in one knee, using CT scans to plan t…

This study collected bone, cartilage, skin, and fat tissue from 50 patients undergoing surgery at Children's National Medical Center. The goal was to grow cells from these tissues in the lab and analyze them to better understand bone and connective tissue diseases. The study was …

This study looked at whether a single IV dose of oxytocin, a natural hormone, could reduce pain from heat on the skin. It included 7 people — some healthy and some with severe knee arthritis. Researchers measured pain scores during a 5-minute heat test. The study was terminated e…

This study looked at different X-ray views and MRI scans to see which best shows cartilage damage in arthritic knees. Researchers planned to include 225 people with knee osteoarthritis, but only 8 were enrolled before the study was stopped. The goal was to improve how doctors dec…
