Gender seems to play a role when it comes to the risk factor of developing Osgood Schlatter disease. The disease is more common in boys than in girls. The percentage of boys who develop the disease is higher than the number of girls overall.
However, over the past several years the gender gap in incidences of Osgood Schlatter disease has started to narrow. The main reason for this is likely because there are more and more girls playing sports. This increase in the number of girls playing sports is likely the main cause of the increase in the number of girls now developing this disease.
It seems that one of the highest risk factors of developing Osgood Schlatter disease is playing sports that are strenuous on the knees. This can happen to both boys and girls equally when they are playing the same types of sports or participating in the same types of activities.
