Which of these bones does not contribute to the knee joint? The biomechanics of the knee are detailed by describing the roles of the anatomic structures and their relationships in the uninjured knee. The ankle joint has a larger weight-bearing area compared with the hip and knee (1100–1300 mm 2) enabling the ankle to spread load over a large area and reduce stress across the joint. Altered knee joint biomechanics and excessive joint loading have long been considered as important contributors to the development and progression of knee osteoarthritis.
