From: Increased lower limb length ratio in patients with patellar instability
Measurement of lower limb length ratio. a The femoral length was measured from the superior center of the femoral head (A) to midpoint of the distal femoral condyle (C) when the mT/F ratio was calculated. The femoral length was measured from the top of the greater trochanter (B) to the center of the femoral condyles when the aT/F ratio was measured. b Tibia length was measured from the tibial plateau (D) to center of ankle joint (E)
