Reason: R knee OCD lesion assessment s/p fixation History: R knee pain/swelling MENISCI: The medial meniscus appears intact. Lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There are 4 radiolucent tubular fixation devices present within the medial femoral condyle extending to the articular surface. There is mild heterogeneity of the lateral articular cartilage of the medial femoral condyle as well as a tiny partial-thickness defect immediately distal to one of the screws, but otherwise the surface of the articular cartilage appears smooth and we see no full-thickness fluid-filled defect. There is mild edema within the marrow along the fixation devices, which is of questionable significance. Of note, the orientation of the distal end of the most posterior fixation device within the articular cartilage is slightly different than that of the remainder of the device, which could represent shearing, but this is of uncertain significance.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: There is thickening of the proximal patellar tendon with linear intermediate signal intensity traversing the tendon on the axial images, that may represent a combination of tendinosis and tearing or postsurgical changes. The quadriceps tendon appears intact.ADDITIONAL
