Peeler J, Leiter J, MacDonald P. Accuracy and reliability of anterior cruciate ligament clinical examination in a multidisciplinary sports medicine setting. Another test for diagnosis is the Pivot shift test which is done by going from extension to flexion of the knee,and the tibia will be reduced at 20-30 degrees of flexion.The test measures the functional instability of the knee or the giving away of the knee.Pivot shift is pathognomonic for a ACL tear and is best demonstrated in the chronic setting.It is a more difficult test than the Lachman test. Explain the interprofessional team strategies for the prompt evaluation of patients with suspected anterior cruciate ligament (ACL) injuries to expedite diagnosis and management.
