Reason: Left knee continued pain and swelling s/p microfracture of femoral trochlea, chondroplasty MFC, evaluate healing History: left knee pain MENISCI: The medial meniscus is intact. There is pulsation artifact which obscures the root of the lateral meniscus on multiple views and a root avulsion cannot be excluded. The remaining lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: Patellar and trochlear cartilage diffusely thinned but without focal defects. There is full-thickness cartilage loss along the posterior lateral femoral condyle measuring 5 mm in length which is new since the prior exam. Associated underlying marrow edema is also noted. Partial-thickness cartilage loss along the anterior femoral condyle as seen previously is improved status post microfracture, with resolution of associated subchondral cysts and marrow edema. Diffuse thinning of the articular cartilage is otherwise noted in both compartments.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: Patellar and quadriceps tendons are intact.ADDITIONAL
1.New focus of full-thickness cartilage loss along the posterior lateral femoral condyle with associated underlying marrow changes2.Increased cartilage along the anterior lateral femoral condyle status post microfracture.3.Moderate size joint effusion.
