Patellar orientation
WebPatellar orientation is defined as the tri-planar position of the patella within the femoral sulcus. The four components of patellar orientation described by McConnell (21) are pa- tellar tilt, glide, anteroposterior tilt, and rotation.

WebA patella dislocation occurs when the knee cap pops sideways out of its vertical groove at the knee joint. It’s usually caused by force, from a collision, a fall or a bad step. A dislocated patella is painful and will prevent you from walking, but it’s easy to correct and sometimes corrects itself. Appointments 216.444.2606 Appointments & Locations Webties. Realignment of the patella through conservative techniques has become the main emphasis of treatment. Due to this emphasis on patellar realignment, a need for a quantitative measurement of patellar orientation has developed. The A-angle is a goniometric measurement that assesses the relationship of the patella to the tibial tubercle.
