Patella dislocation: During knee flexion, the knee cap or patella normally tracks in a groove in the distal femur called the trochlea. During a patellar dislocation, a traumatic event causes the patella to track outside of this groove while the knee flexes. This can injure some of the stabilizing structures surrounding the patella and can place a patient at risk fora future dislocation event.
