Blackburne and Peel Method
- 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;
- Aglietti, et al. (1983)
- 150 Rt. knees: AB ratio = 0.95 w/ range of 0.65 to 1.38
- Patellar pain and incongruence. I: Measurements of incongruence.
Observations on patellar height after proximal tibial osteotomy.
