Basically, it consists of three bones and two joints. The bones are Femur, Tibia and Patella while the joints are tibiofemoral and patellofemoral joints. The tibiofemoral joint is a complex hinge joint between tibia and femur.The patellofemoral joint between femur and patella is a gliding synovial joint.rticular surfaces of knee joint: Superiorly, there are rounded condyles of femur and below are the condyles of tibia and their cartilaginous menisci. In the front, the articulation takes place between more or less flat surface of patella and lower end of femur on the anterior side.
