What degree of flexion does the knee reach during midstance?

• A. 15-18 degrees
• B. 30 degrees
• C. 5 degrees
• D. Fully extended

Answer: (D)

During midstance in gait, the knee generally approaches a position that is close to fully extended. In this phase of walking, the body weight is directly over the supporting leg, and the knee is stabilized to support the weight. A fully extended position allows for maximal stability and the ability to transfer weight smoothly to the opposite leg while minimizing energy expenditure. The midstance phase is characterized by the alignment of the body so that it can effectively balance and propel forward. While some degree of residual flexion may be present due to individual differences or specific gait patterns, the normative biomechanical understanding of midstance indicates that the knee is predominantly in a neutral to fully extended position. Thus, this phase is crucial for maintaining stability and creating a smooth transition in the gait cycle.
