Genu valgum, commonly called "knock-knee", is a condition in which the knees angle in and touch each other when the legs are straightened. [1] Individuals with severe valgus deformities are typically unable to touch their feet together while simultaneously straightening the legs.
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
The tibia (/ ˈ t ɪ b i ə /; pl.: tibiae / ˈ t ɪ b i i / or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle.
Kneeling with only one knee, and not both, is called genuflection. Kneeling is a primate behavior used to convey deference by making the figure that is kneeling appear smaller than the other.

Coming to a sudden stop when running; A direct contact or collision to the knee (e.g. during a football tackle or a motor vehicle collision) [1] These movements cause the tibia to shift away from the femur rapidly, placing strain on the knee joint and potentially leading to rupture of the ACL. About 80% of ACL injuries occur without direct ...
