Evaluation the Association between Adduction Moment and Pain in Subjects with Knee Osteoarthritis: A Systematic Review of Literature

Background: There is no doubt that the number of subjects with knee Osteoarthritis (OA) is increasing. Most of the subjects with knee OA have functional limitations due to pain. However, in most research studies on knee OA and investigation of the influence of various treatment interventions, the magnitude of adductor moment has been used to represent the severity of OA and the effects of interventions. However, the main question posed here is that is there any association between pain and adductor moment in the knee joint. Therefore, this study aimed to investigate the association between knee pain and adduction moment.

Method: This was a systematic review in which, a search was done in some databases including PubMed, ISI web of knowledge, Embase, and Scopus for a period between 1960 and 2020. Some keywords such as knee pain, orthosis, wedge, rehabilitation, exercise were used in combination with knee pain and adduction moment. The quality of studies was evaluated by the Pedro scale.

Results: 21 papers were selected for final analysis with quality varied between 6 and 9. 9 papers focused on both adduction moment and pain without any intervention, 2 papers on the effect of using a brace on knee adduction moment and pain, 6 papers on the use of exercise on knee pain and moment and 4 papers on influence of insole on knee pain and adduction moment.

Conclusion: Although most investigators claim that there is a positive association between adduction moment and pain, this correlation is controversial. Therefore, it is recommended to determine the association between these parameters in a big study.
