Jolt Test \/ Nakajima N-Test | Anterior Cruciate Ligament Tear<\/h2>\nAround the time that the Pivot Shift test<\/a> of Macintosh for the ACL was proposed, Nakajima et al. (1972)<\/a> observed a similar jolt of the ACL-deficient knee during examination using their \u201cn-test\u201d. However, this procedure has not undergone diagnostic accuracy assessment and the clinical value thus remains questionable.\n

We are going to describe the procedure for the right knee.\n\nThe patient\u2019s knee is flexed to 90\u00b0. Using your right hand, pick up the patient's leg by grasping the lateral side of the ankle and applying internal rotation.\n\nYour left hand rests on the lateral aspect of the patient\u2019s knee and applies a valgus force. At the same time, place your thumb on the posterior aspect of the head of the fibula.\n\nThe knee is then gradually extended.\n\nThe test is positive if the tibial plateau suddenly subluxates anteriorly and medially with a palpable jolt that usually occurs at around 40-20 degrees of extension. The patient may also report that sensation as the \u201cgiving-way\u201d feeling they experience during activities.\n\n[cta]\n\nOther common tests to assess for an ACL tear are:\n
