Web30 de jul. de 2024 · A review regarding the quality assessment of radiological measurements identified the following metrics as most useful for the assessment of trochlear dysplasia 11: the lateral trochlear inclination (LTI), the crossing sign, the trochlear bump, the TT-TG for planning treatment, the trochlear depth and the ventral trochlear prominence. See also WebA TT-TG distance of more than 20 mm is nearly always associated with patellar instability, and is a measure for lateralization of tibila tuberosity more reliable than the Q angle because it is not dependent on patella position. Values of 15–20 mm are considered borderline and distances less than 15mm are considered normal.
