Fig. 1 Contributions of mechanical factors to knee joint contact force (output), illustrating the potential variation in each factor (sliding colour scales) and the variable influence of load modifying interventions, such as lateral wedge insoles (input). External loads include ground reaction forces and body segment accelerations (A); muscle forces originate from both knee-spanning and other lower limb muscles (B); constraint is also provided by passive structures such as ligaments (C) and altered joint geometry may alter the patterns of focal stress in the knee joint (D). The influence of each factor may also change according to the severity of knee OA, altering the capacity of load modifying interventions to modify each component and its contribution to joint contact force.
