Female, 57 years old. Status post right knee arthroscopy microfracture of medial femoral condyle and trochlea. MENISCI: There is fragmentation of the body of the lateral meniscus with a prominent horizontal tear extending from the body into the anterior horn. The posterior horn of the medial meniscus appears small, which likely relates to prior partial meniscectomy. Abnormal fluid signal between the medial meniscus and MCL may also be related to previous procedure.ARTICULAR CARTILAGE AND BONE: Marrow signal abnormality at the lateral femoral condyle is increased in prominence from the prior study, with overlying cartilage thinning with small focal full-thickness defect. There is diffuse cartilage thinning elsewhere in the medial and lateral compartments, without additional full-thickness defect identified. There is a full-thickness cartilage defect at the femoral trochlea near the apex measuring up to 7 mm, with underlying mild marrow signal abnormality which may in part relate to prior microfracture procedure. Patellar cartilage is grossly intact.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1.Tear of the body and anterior horn of the lateral meniscus. Changes compatible with prior partial meniscectomy of the medial meniscus.2. Focal cartilage defects involving the lateral femoral condyle and the trochlea with additional mild scattered cartilage thinning as above.
