How is the knee joint formed?
Knee Joint. … The knee, also known as the tibiofemoral joint, is a synovial hinge joint formed between three bones: the femur, tibia, and patella. Two rounded, convex processes (known as condyles) on the distal end of the femur meet two rounded, concave condyles at the proximal end of the tibia.
How does a hinge joint work?
These joints are formed when two or more bones meet and move along an axis to bend. Consider how our elbows bend when we lift a glass or how our fingers curl when we make a fist. Hinge joints are assisted by other tissues, including cartilage and ligaments, to connect and bend.
How do cruciate ligaments provide stability?
Ligaments attach from bone to bone and provide the stability around a joint. … The posterior cruciate ligament (PCL) prevents the femur from sliding forward off the top of the tibia. As is characteristic of all hinge joints, collateral ligaments are found at the sides of the knee joint.
