Imaging Studies:
Radiographic evaluation is the first investigation performed. Whena lesion is detected radiolucenta appears in osteochondralarticular epiphysis. In early lesions patients may be normalradiographs. The affected knee medial femoral condyle lesionsare visualized.
Schintigrafia bone with techenetiu is important to assessosteocondritei dissected. The degree of abstraction is animportant indicator of bone healing osteocodnral fragment. The more so is the capture higher osteoblastic activity and canincrease healing conservative.
MRI is useful for evaluating patients with osteochondritisdissecans. Allows viewing of the body loses the degree of detachment. Lesions that appear normal on X-rays can bedetected with magnetic rezoannta. Allows determining the integrity of articular surfaces and fluid interfaces. It is useful to determineplanning perioperativa fragment detachment. Intra-articularinjection of gadolinium can be given because they increase thesensitivity and specificity of magnetic rezoanantei.
Sonography (ultrasound) is used to assess knee andosteochondritis dissecans of the humeral capitelum. The advantages of sonography are its low cost compared to theresonance tomography scanning and dynamic movement of theaffected joint.
