Explanation
The knee joint is where the tibia and femur meet. Running parallel to the tibia is the fibula, the thinner and weaker bone of the lower leg. 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 The smaller bone that runs alongside the tibia (fibula) and the kneecap (patella) are the other bones that make the knee joint.So assertion and reason both are true But Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. Is the condition for classifying joint as hinge joint Answer : (d)
