Dynamic magnetic resonance imaging in cases of patello-femoral joint mal-tracking

Patello-femoral disorders commonly cause anterior knee pain and giving way. Axial X-rays will only reveal mal-alignment but not mal-tracking. In a group of 32 patients 54 knees were studied by dynamic MRI. Group A which presented with recurrent subluxation or dislocation showed more moderate and severe tilt and subluxation, than group B that presented with anterior knee pain. Dynamic MRI gives us a new perspective for dynamic study of the patello-femoral joint
