Marie Madeleine walking for the first time after surgery with Suzette Griffioen, Physical Therapist. See SWNS story SWOCknee. A teenager who had a disability which meant her knee bent backwards had life-changing surgery – so now she can walk to school with pride. Marie Madeleine, 13, developed an unusual disability as a young child which meant her knee bent backwards. As Marie, from Senegal, grew to a teen it worsened and she had to limp to school each day – and she often struggled to keep up with her friends. Although her family supported her, they started to worry how her condition would hold her back in life – and prayed for a “miracle” so she could be like every other schoolgirl.
