Mahmoud is an eight-year-old child, who lives together with his family in a house that lacks the most basic necessities of life and does not protect them from the cold winter nights. Mahmoud's father does not work, and has sold some of his furniture in order to provide for his family. Mahmoud suffers from left arthrofibrosis in his knee that was caused by the extension of the left knee bone. This resulted in his inability to move and walk and he is today in dire need of a patellar tendon transfer operation. Would you help us relive the pain of this child?
