Patellofemoral disorders presenting as bilateral locked knees in achondroplasia.
Patellofemoral disorders in achondroplasia, to our knowledge, have not been reported in the literature. We describe an unusual case of bilateral locked knees in an achondroplastic patient secondary to intra-articular subluxating patellae and symmetrical chondral flap lesions of the femoral trochlea which were treated by arthroscopic resection. We suggest that abnormal kinematics may cause patellofemoral complications in achondroplasia.
