Patellar maltracking is the most common complication of primary TKA.
The dynamic forces affecting patellar tracking are represented by the Q-angle, formed by a line from the ASIS to the patella and from the tibial tubercle to the patella. A normal Q-angle is between 12-20°.

The static transverse stabilizers of the patella include the medial/lateral retinaculum and medial/lateral patellofemoral ligaments.
The dynamic transverse stabilizers include the IT band and vastus medialis/lateralis.
