Summary

Multi-ligament knee injuries (MLKIs) can occur during military training, sports injuries, or traumatic events such as motor vehicle accidents and can be devastating events. These complex injuries involving disruption of 2 or more ligaments often coincide with injuries to arteries, nerves, tendons, menisci, and/or fractures and can be devastating events. MLKIs often require complex treatments nearly 2 in 5 patients suffer complications after surgery. Loss of knee range of motion is the most common complication and is associated with military separation. There are also long-term effects of motion loss, as the need for motion-restoring surgery after MLKI is associated with an increased risk of osteoarthritis within 5 years of surgery. A person's ability to perform both activities of daily living and higher demand physical activities is often impaired both in the short and long term. In fact, only 1 in 3 people return to high-level sport after MLKI. The purpose of this translational randomized clinical trial is to determine if a 30-day course of oral Losartan improves a person's ability to return to work or sport, range of motion and strength, and reduce knee inflammation in the first year after surgical treatment of an MLKI.

Conditions

  • Multi-ligament Knee Injury

Interventions

DRUG

losartan 25 mg

Losartan is an angiotensin-II inhibitor that modulates the renin-angiotensin system by blocking the activation of angiotensin type 1 receptors, thus preventing binding with angiotensin-II and decreasing blood pressure. Losartan has a broader therapeutic potential for muscle healing and treatment for diseases ranging from rheumatoid arthritis, osteoarthritis, chronic kidney disease, Marfan syndrome, and fatty liver. TGF-β plays an active role in fibrosis leading to the formation of adhesions and scar tissue. By limiting the formation of adhesions and scar tissue, losartan may reduce pain, myofibroblast activity, synovitis, fibrosis, and cartilage degeneration.

OTHER

Placebo capsule

The placebo capsule will look identical to the active study drug, but will not have any active ingredient and will be filled with corn starch
