FIGURE 42.9 Approach to the patient with a subacute knee injury. AP, anteroposterior.
Often, a patient may come to the ED with a history of trauma and knee pain
that has been present for more than 2 or 3 days (see Fig. 42.9 ). In addition to the
standard AP, lateral, and patellar views, a tunnel or intercondylar view should be
taken to exclude fracture, tumor, and OCD. If the initial knee and hip
examinations do not suggest a diagnosis and no signs of infection exist, the
diagnostic maneuvers in Table 42.2 should be completed. The patient may have a
subacute collateral ligament, cruciate ligament, or meniscal injury and require an
orthopedic referral.
