The research area of knee focuses on studying the structure, biomechanics, function, and potential treatments for issues related to the knee joint. This includes understanding the causes and mechanisms of knee injuries, such as ligament tears, meniscus tears, and osteoarthritis, as well as developing new surgical techniques, rehabilitation protocols, and non-invasive treatments to improve knee function and reduce pain. Researchers in this field may use a variety of techniques, such as imaging, biomechanical analysis, and clinical trials, to advance our knowledge and improve outcomes for individuals with knee-related problems.
