Differential diagnosis is a process that examines the patient's signs and symptoms and leads the clinician to reach a diagnosis.  This website was designed by second year Physical Therapy Students at AT Still University in Mesa, AZ to guide clinicians through a differential diagnosis thought process in regards to knee pain.
