Measurement of Tibial Tuberosity–Trochlear Groove Offset …
WebJul 26, 2015 · A TT-PCL distance ≥24 mm was found to be less predictive of recurrent instability in this series. For patients experiencing multiple episodes of patellar instability in the setting of a normal TT-TG distance, obtaining the TT-PCL measurement may provide a more focused assessment of the tibial contribution to tubercle lateralization. III. WebLateralization of the tibial tubercle is one of the predisposing factors for Patellar Dislocation. In this post we look at what the normal position is, how to measure lateralization and what the differences between CT and MRI … can phenylalanine be phosphorylated
