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…

Researchers at Ohio State University are running a double-blind, randomized trial to compare three single-dose injections for knee osteoarthritis: Zilretta, Synvisc-One, and Monovisc. The study enrolls adults aged 25 to 85 with painful knee osteoarthritis that continues despite p…

This study tests whether a mindful walking program can help people with knee osteoarthritis walk better and more often. Participants are randomly assigned to either a mindful walking group or a self-care education group, both meeting over 11 sessions in 6 months. The study focuse…

This study looked at whether using a forced-air warming blanket during knee replacement surgery helps prevent hypothermia (low body temperature) and related problems like shivering. Researchers compared 240 patients who either got the warming blanket or standard care. The goal wa…

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 looks at how oxytocin, a natural hormone, affects the part of your nervous system that controls rest and digestion. Researchers will give a single injection of oxytocin or a placebo to 38 people (some with knee arthritis, some healthy) and measure tiny changes in pupil…

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, …
