Patient Presentation:
A five year-old male presents with his grandmother to the sports medicine clinic with the chief complaint of left knee pain.

Ten days before presentation, the patient's sister landed on his left anterior knee at a trampoline park. Afterwards, he could not bear weight fully, and he had swelling prompting an emergency room visit where x-ray s were normal. He has been using ibuprofen three times per day for pain relief. He denied any giving way, catching, locking, popping, numbness, or tingling.
