Combination Exams and Selection of Knee Ligament Special Tests:

The routine combination of patient history, physical examination and radiographs, is as accurate as MRI for diagnosing anterior cruciate ligament (ACL) injury (1, 4 - 15). The combination exam is also very accurate for posterior cruciate ligament (PCL) injuries (1, 9, 15 - 17), and is specific, but may lack sensitivity, for collateral ligament injuries (1, 16, 17). Unfortunately, these studies lack the detail necessary to identify an optimal set of subjective exam questions, special tests, movement assessments, and/or radiographs that could be recommended to other professionals. At this point, no studies could be located regarding a "test-item cluster" for knee ligament injury, but based on results from the combined exams, more consideration should be given to this line of
