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.
