Introduction: The severity of the symptoms and the risk factors connected to them have not been described, but knee pain can be a common complaint during pregnancy. The purpose of this study was to identify knee-related dysfunction in a general obstetric population and to list risk factors. Material and Methods: In this systematic review, Patients in obstetric clinics completed the Pregnancy Physical Activity Questionnaire (PPAQ), a validated instrument to measure physical activity, as well as the International Knee Documentation Committee (IKDC) questionnaire to assess their knee function. To find independent associations with IKDC score and identify predictors of knee dysfunction, analyses of age, weeks of gestation, height, weight, and history of knee issues prior to pregnancy were performed. Results: A mean PPAQ score of 248 MET-h/wk, with a range of 40 to 805 MET-h/wk, was used to estimate physical activity in the study population. With no discernible differences between trimesters (7.3 percent, 6.3 percent, and 6.1 percent in the first, second, and third trimester groups, respectively), twenty (6.5 percent) women reported having a PPAQ greater than 500 MET-h/wk. Seventy-six (24%) of the women in this study reported a history of knee surgery, an injury, or other knee issue. Conclusion: A high level of activity, younger age, higher BMI, and a history of knee problems were all associated with severe knee dysfunction, which was reported by 26.1% of pregnant women. These findings might have consequences for pregnant women who want to stay active and fit during their training. Future research is advised to evaluate the need for intervention and to determine the best ways to prevent and treat symptoms in this population.
