Radiographs showing CMF of the tibia with postoperative appearances following curettage and cementoma. (a) Anterior-posterior radiograph of the left knee showing a lytic lesion (arrow) in the medial tibial plateau with a thin, partially sclerotic margin and very mild bone expansion. There is no appreciable matrix mineralisation, and the articular surface of the knee joint is well-preserved. (b) Anterior-posterior radiograph of the left knee following curettage and cementation (arrow), showing satisfactory post-operative appearance.
