title: Editorial Commentary: Elevated Tibial Tubercle-Trochlear Groove Distance and Patellar Instability.
abstract: In patients with unilateral patellar instability, tibial tuberosity-trochlear groove, lateral patellar tilt, and subluxation are greater on the side of instability. Dynamic computed tomography scan may represent a more physiologic assessment of patellofemoral tracking. A laterally positioned tuberosity may be a predisposing factor for patellar instability, a role perhaps further defined by future dynamic studies of the extensor mechanism.
