Case:The cause of osteochondritis dissecans is unknown. Various hypotheses suggest mechanical, ischemic, and hereditary causes. We describe a 13-year-old girl with spastic diplegia, a form of cerebral palsy, who had an associated crouch gait and presented with bilateral osteochondral defects of the medial and lateral femoral condyles.Conclusion:This case highlights the potential role of repetitive microtrauma, likely due to the poor biomechanical forces in a crouch gait, and provides support for a mechanical cause of osteochondritis dissecans.
