The Effects of Tibial Tuberosity-Trochlear Groove Distance on Lateral Translation of the Patella: A Cadaveric Biomechanical Study
Key Points
Lateral translation of the patella increases as tibial tuberosity-trochlear groove distance exceeds 20 mm, altering biomechanics.
A notable linear relationship exists between translational force and anatomic alignment with distances below 20 mm.
Cadaveric biomechanical study design confirms the influence of tibial tuberosity positioning on patellofemoral dynamics.
Understanding these thresholds is crucial for interventions aimed at correcting patellar alignment in clinical settings.
Abstract
The linear relationship identified between translational force and anatomic alignment, with TT-TG distances 20 mm confirms a threshold at which patellofemoral biomechanics are altered.
