Technical report: radiological evaluation of patellar malalignment using a new frame for axial imaging of the patellae.
Axial radiographs were performed on 59 children and adolescent patients with patellar malalignment using the method described by Laurin. A special frame was used to keep the knees in 20 degrees flexion and to maintain standard conditions. Radiological indices were measured before realignment surgery. A statistically significant difference (P < 0.0001) in the lateral patellofemoral angle was observed comparing malaligned and control patellae. Laurin's technique using a special frame provides a method of obtaining standard radiological measurements of patellar malalignment for use in surgical planning.
