- Discussion:
- ratio between perpendicular distance from
lower articular margin of patella
to
tibial plateau (A) and the
length of articular surface of patella (B)
(use lateral view w/ knee in at least 30 deg of flexion);
- AB ratio in 171 normal knees was 0.80 w/ no gender diff;
- Agliettis et. al. Clin. Ortho 1983
- 150 Rt. knees: AB ratio = 0.95 w/ range of 0.65 to 1.38;
