The movement of the torso that results when the non reference limb swings forward carries the torso over the reference limb. The knee joint of the reference limb assumes an extended position. This lengthens the limb facilitating the ability of the limb to support the weight of the torso.

The suprapatellar bursa permits free movement of the quadriceps tendon over the distal end of the femur and facilitates full extension and flexion of the knee joint.

Extension is the type of movement allowed by the knee joint, which increases the angle between the femur and tibia. The individual muscles comprising this group are the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris.

Table 2 indicates the mean and SD of pre- and post-operative ranges of active and functional knee joint motion for the affected knee. The mean value for active extension (flexion contracture) fell from 5.7° preoperatively to 0.8° postoperatively.

The knee-joint was formerly described as a ginglymus or hinge-joint, but is really of a much more complicated character. It must be regarded as consisting of ... This third phase by which all these parts are brought into accurate apposition is known as the “screwing home,” or locking movement of the joint.
