OA knee patients, especially patients who have varus malalignment, had higher peak adduction moments in comparison to the normal population. This acts to rotate the tibia medially on the femur while walking.
The knee adduction moment tends to force the knee outwards, compressing the medial joint compartment and stretching the lateral joint structures. This adduction moment also relates to the severity and progression of the disease, higher adduction moments are related to a higher rate of disease progression.
High, peak knee adduction moments were positively associated with greater pain and were negatively associated with the knee functional score in OA knees.
Therefore, it is always better to either increase the strength of the abductors or reduce the strength of the adductors. By doing so, we can easily stop the progression of OA knee and improve the functions with time.
OA knee (Uni-compartment) is very responsive to conservative treatment if used appropriately and on time.
Surgery can be avoided if intervention is directional and timely interventions.
