Study Notes

The knee joint moves through cycles of flexion and extension during the gait cycle
Knee flexion at loading response provides shock absorption and assists in weight transfer
Knee extension during midstance minimizes muscular effort during single limb weight-bearing
Maximum extension at the knee occurs during terminal stance
Knee achieves maximal stance-phase flexion at 35° to 40° by preswing
Knee flexes during initial and midswing to shorten the limb and clear the foot from the floor
Maximum knee flexion occurs during midswing at 60° to 65° of flexion
Knee extends during terminal swing to assist in achieving an adequate step length
Knee is near full extension at initial contact and achieves full extension during terminal stance
Knee assists other limb joints in advancing the limb and preparing for initial contact once again.
