BEIRUT – It takes him a good 20 seconds to get his bearings, but, sitting up in his bed, Matti Tourrani smiles, and, voice muffled by a drowsy cough, says hello. His right leg is swollen – so much that it is now twice as thick as his left. “It’s not so painful; I’m more concerned about my knee,” says the elderly man. Mr. Tourrani traveled with his wife Maysoun from their small village near Mosul in northern Iraq . He’s in Beirut for knee-replacement surgery, a procedure that will cost more than $23,000 and for which the family mortgaged their house. Their part of Iraq is still violent: Last week a bomb killed two people just a mile from their home. “We’re used to it by now,” Maysoun says. But the family is concerned that they might have traveled in vain. Before any knee surgery, the leg must heal more, says Irad Beldjebel, a doctor who works helping Beirut’s unknown thousands of refugees.
