Patient History: A 22-year-old woman presents to the emergency department with left knee pain after a motor vehicle accident. Her left knee struck the dashboard during the accident, and it now hurts with any movement. Physical Examination: She has tenderness to palpation and ecchymosis over the left patella.

She has no deformity of the patella and is able to straight leg raise. Active knee extension increases her pain. Anteroposterior and lateral X-rays of the left knee show a non-displaced transverse patella fracture. Source: Clinical Advisor
