A 48-year-old male presented to the Emergency Department for bilateral anterior knee pain after playing pick-up basketball.

History:
A 48-year-old male with no significant past medical history and not on any medications presented to the Emergency Eepartment for bilateral anterior knee pain. While playing pickup basketball, he jumped for a rebound, landed on both feet, and felt a pop on the anterior aspect of his both knees. He was unable to ambulate or fully extend his knees despite being able to fire his quadriceps muscles. He reported he was recently training for a sprint triathlon and bicycling more than usual but denied any previous knee issues.

Physical Exam:
