Anterior cruciate ligament rupture

This study looks at whether the amount of tension applied to a new ACL graft during knee surgery influences the development of arthritis over at least 15 years. About 168 people with a torn ACL in one knee will be followed, comparing two common tension settings. The goal is to se…

This study looked at two ways to do revision ACL surgery—using an Achilles tendon graft alone or with an extra InternalBrace for support. Thirty-two people with a failed ACL graft were randomly assigned to one of the two procedures. Researchers measured knee function, symptoms, a…

This study looked at 70 people who had surgery to fix a torn ACL in their knee. Doctors compared two different types of tendon grafts—one from the quadriceps (thigh) and one from the hamstrings (back of thigh)—to see which led to better knee function and stability. Participants w…

Researchers compare the Werewolf FLOW 50 electrocautery device with standard care during ACL reconstruction in patients aged 12 to 18. The trial measures how many participants develop arthrofibrosis, a complication that restricts knee movement, and tracks knee range of motion and…

This trial explores whether using a custom 3D-printed knee extender, along with a home exercise program, helps people regain knee motion after ACL surgery. Participants who had an ACL tear will use the device at home and report their progress. The study measures how quickly they …

This study looks at two different tendon grafts used to repair a torn anterior cruciate ligament (ACL) in the knee. Researchers want to see if one type of tendon heals better and causes less change to the bone tunnels than the other. The study involves 58 people aged 18 to 45 who…

This study looked at 29 people who had ACL surgery using their own hamstring tendons. Researchers used a special ultrasound to check how stretchy the healed tendons were and compared them to the healthy leg. They also tested leg muscle strength to see if tendon quality affects re…

This study looked at whether adding brain-focused education and cross-training (exercising the uninjured leg) early after ACL surgery helps recovery. 29 adults aged 18-40 who had ACL repair participated. Researchers measured leg strength, brain structure, and brain activity to se…

This study looked at 120 children who had ACL surgery using one of two techniques: an older method that drills across the growth plate, or a newer method that avoids it. Researchers checked X-rays, knee function, and patient questionnaires to see which approach caused fewer growt…
