In the CR group, movement from full extension to maximum flexion resulted in average AP translations for the medial and lateral condyles of 4.3 [+ or -] 3.5 mm (−3.0-9.4 mm) and 7.9 [+ or -] 4.2 mm (2.4-10.6 mm), respectively.
It was observed at the tendomuscular junction, articulating with posterior aspect of the lateral condyle of the tibia and lying close to the head of the fibula.
The latter, in addition, depends on another preponderant factor such as the considerably larger size of the medial condylar surface of the humerus compared to the lateral condyle (Taylor).
In fractures of lateral condyle, ORIF is indicated when lateral tilt or valgus mal-alignment more than 50, articular step off more than 3mm or condylar widening more than 3mm.(26)
