In what seems to a medical first we have a pendant to cases of tennis elbow and joggers nipple, I bring you 'devotees knee'.
According to an article in the Copenhagen post, culled from the Jyllands-Posten, it appears that devout Muslims are prey to debilitating pains due to theposture they take up suring prayer.

"Some injuries in the back and knee are directly linked to the prayer posture, while others are not allowed to heal because they are strained five times a day during prayer,"
