T Mapping of Patellar Cartilage After a Single First-Time Episode of Traumatic Lateral Patellar Dislocation.

Background: In most cases, lateral patellar dislocation (LPD) is accompanied by chondral injury and may initiate gradual degeneration of patellar cartilage, which might be detected with a T mapping, a well-established method for cartilage lesions assessment.

Purpose: To examine short-term consequences of single first-time LPD in teenagers by T mapping of the patellar-cartilage state.

Study Type: Prospective.
