Knee Joint Force in Normal and Pathological Gait

  • Ian J. Harrington


Knee joint loading in normal adults is characterized by three distinct joint force peaks corresponding to force actions generated in the hamstring, quadriceps and gastrocnemius muscles. These peaks tend to be absent during load transmission in pathological knees. The resultant knee joint force is transmitted primarily through the medial joint compartment in normal knees but in pathological joints, particularly those with varus-valgus angulation, its force (the centre of joint pressure) is frequently unpredictable and there are no distinct peaks. The magnitude of the knee joint bearing force tends to increase with increasing angular deformity but does not exceed normal joint loading values. Joint force transmission in prosthetic knees does not follow a normal loading pattern but is more typical of pre-operative loading profiles.
