Advance in Biomechanical Parameters of Knee Osteoarthritis (review) / 中国康复理论与实践

ABSTRACT

Knee osteoarthritis is a common chronic degenerative disease in the elderly. Its occurrence and development are closely related to biomechanical factors. The force of knee joint is affected by different factors, such as joint morphology, lower limb alignment, muscle contractions, external load, soft tissue traction and so on. Due to the limitation of in vivo measurement, biomechanical parameters based on motion analysis techniques have been widely used in clinical research. At present, biomechanical parameters which are widely studied and applied in clinical research include knee adduction moment, knee adduction impulse, knee flexion moment, and knee varus thrust. It is important to observe the changes of knee joint biomechanical parameters during the occurrence and development of knee osteoarthritis for researching etiology, diagnosis, intervention and treatment.
