Medial marginal fracture of the patella following patellar dislocation

摘要: Among patients with patellar dislocation, a small fragment is occasionally found along the medial border of patella. However, detailed pathology this fracture has not been clearly described, especially in relation to patellofemoral ligament (MPFL). The purpose study was describe MPFL. subjects were seven an acute primary dislocation showing marginal An open exploration performed confirm relationship between and MPFL repaired by re-attachment patella anchors. site determined location anchors post-operative plain radiograph. fragments continuous thick taut all cases. Re-attachment stabilized against lateral shift manual force improving tracking. All returned their pre-injury activity level without any episodes recurrent or subluxation at final follow up (av. 31 months). Medial avulsion that occurred middle one-third
