A 15-year-old male reports dull pain in both knees. Sometimes one or both knees click, and the patient describes a catching sensation under the patella. In determining the causes of the knee pain, what additional history do you need? What categories can you use to differentiate knee pain? What are your specific differential diagnoses for knee pain? What physical examination will you perform? What anatomic structures are you assessing as part of the physical examination? What special maneuvers will you perform?

With regard to the case study you were assigned:

Review this week’s Learning Resources, and consider the insights they provide about the case study.
Consider what history would be necessary to collect from the patient in the case study you were assigned.
Consider what physical exams and diagnostic tests would be appropriate to gather more information about the patient’s condition. How would the results be used to make a diagnosis?
Identify at least five possible conditions that may be considered in a differential diagnosis for the patient.
