Leg/Knee Case 6 History/Physical Exam
Patella Dislocation
History and Physical Exam
Patella dislocations often occur when the patient pivots quickly with the knee flexed. The rapid forceful contraction of the vastus lateralis dislocates the patella. Common mechanisms are dancing, gymnastics, and trying to catch oneself from falling.
Patients complain of severe knee pain. The knee is held in slight flexion. The patella is usually in an obvious lateral position. A neurovascular exam should be performed before and after reduction.
