Reason: R knee medial femoral condyle OCD lesion History: R knee pain/swelling MENISCI: The medial and lateral menisci appear intact.ARTICULAR CARTILAGE AND BONE: Again seen are four tubular fixation devices within the medial femoral condyle extending to the articular surface. The most anterior device appears to penetrate the anteromedial cortex with its end lying just deep to the medial patellofemoral ligament, but this is unchanged from the prior study. Marrow edema along these fixation devices appears less prominent on the current study than on the prior study. There is minimal heterogeneity of the articular cartilage as well as slight thinning of the cartilage along the anteriormost fixation device, but we see no full thickness fluid-filled defect. The articular cartilage of the lateral and patellofemoral compartments appears normal. LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: Again seen is thickening of the proximal patellar tendon, although signal abnormality within this portion of the tendon has normalized. This may reflect healing tendinosis or postsurgical changes. The quadriceps tendon is normal in appearance. ADDITIONAL
Surgical changes of osteochondral defect fixation as described above with improving bone and soft tissue edema. Although there is minimal heterogeneity and thinning of the articular cartilage of the medial femoral condyle, we see no fluid-filled cartilage defect or other complication. Other findings as above.
