The knee joint is the largest and most complicated joint in the body, formed by the fusion of the femur, tibia, and patella bones. It contains several ligaments like the anterior and posterior cruciate ligaments that provide stability, as well as menisci that act as shock absorbers. Injuries to the ligaments and menisci are common and can be diagnosed using clinical tests, with treatments including physical therapy, surgery such as arthroscopy, or in severe cases, knee replacement surgery.
