title: A novel functional correction method for habitual patellar dislocation using autologous hamstring tendon: a case report.
abstract: Habitual patellar dislocation is an uncommon condition. In this case, a patient demonstrated lateral patellar dislocation in the middle or terminal range of flexion. A functional correction of the patella was devised so that the fixation site of the autologous graft on the femur was able to stabilize the patella selectively during the middle or terminal range of flexion. It is not the anatomical medial patellofemoral ligament attachment of the femur that is essential, but that a relevant fixation point on the femur should be sought in each patient to obtain stabilization of the patella to reverse habitual patellar dislocation.
