49-year-old female with right knee pain, history of right knee arthroscopy with medial and lateral partial meniscectomies, grade 3 chondromalacia of the patella was chondroplasty, extensive microfracture of the patella, medial femoral condyle and lateral tibial plateau (6/4/2015) MENISCI: Linear intrasubstance signal abnormality within the posterior horn of the medial meniscus extending to the femoral articular surface consistent with a tear. Interval increase in degree of extrusion of the body of the medial meniscus. Intermediate signal within the inner edge of the body of the medial meniscus reflective of a radial tear.New globular intermediate signal within the anterior horn of the lateral meniscus extending to the femoral articular joint may represent degenerative tearing.ARTICULAR CARTILAGE AND BONE: Grade IV chondromalacia of the medial tibiofemoral compartment with joint space narrowing, bulky osteophytosis, subchondral sclerosis, and thinning of the articular cartilage. Focal fissuring/laminar tearing is noted along the posterior medial femoral condyle. Focal full-thickness signal abnormality in the posterior medial femoral condyle cartilage with underlying subchondral edema type signal.Grade 1-2 chondromalacia of the lateral tibiofemoral compartment with focal full-thickness chondral defect of the tibial articular cartilage measuring 7 mm in the AP dimension, worsened in the interval. A focal delamination defect is present along the medial aspect of the femoral trochlea. Edema type marrow signal is noted within and around the lateral tibial spine.Grade 2-3 chondromalacia of the patellofemoral compartment worst along the patellar ridge. Postsurgical appearance of microfracture of the lateral facet of the patella.LIGAMENTS: The cruciate ligaments are intact. The collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.New tearing of the body and posterior horn of the medial meniscus with interval increase in degree of extrusion. 2.New globular intermediate signal within the anterior horn of the lateral meniscus extending to the femoral articular joint may represent degenerative tearing.3.Focal fissuring/laminar tearing is noted along the posterior medial femoral condyle is new. Focal delamination defect is present along the medial aspect of the femoral trochlea.4.Worsened focal full-thickness chondral defect in the lateral tibial articular cartilage measuring 7 mm in the AP dimension.5.Severe osteoarthritis affects the right knee, worst at the medial tibiofemoral compartment. 6.Interval resolution of joint effusion. Interval decrease in size of Baker's cyst now containing a 7 mm loose body.
