Biomechanics- GaitNormal gait is defined as (form of bipedal locomotion) or as a method of locomotion involving the use of the two legs, alternately , to provide both support and propulsion at least one foot being in contact with the ground at all times . Van Eijden came up with a series of nine non‐linear equations which could be used to describe: (1) the position of patellar ligament, patella, and quadriceps tendon; (2) the contact point of the patellofemoral joint; and (3) the ratio between the patella tendon force: quadriceps force and the quadriceps force: patellofemoral joint contact force ratio for a given knee and flexion angle. See our User Agreement and Privacy Policy. Abstract: Functionally, the knee comprises 2 articulations—the patellofemoral and tibiofemoral. transmits tensile forces generated by the quadriceps to the patellar tendon ; increases lever arm of the extensor mechanism patellectomy decreases extension force by 30%; Biomechanics patellofemoral joint reaction force . J Rehabil Res Dev. When standing on one leg, on tiptoe, the joint reactive force is approximately 2.1 times body weight, while the Achilles tendon force reaches approximately 1.2 times body weight.
