40-year-old female with a fracture of the right fibula. Evaluate for healing. MENISCI: The medial and lateral meniscus appear intactARTICULAR CARTILAGE AND BONE: There is a full-thickness articular cartilage cleft along the weightbearing surface of the medial tibial plateau with underlying subchondral signal abnormality likely representing a small nondisplaced subchondral fracture (image 20; series 7). There is linear signal abnormality traversing the proximal fibula at the insertion of the conjoined tendon consistent with the stated history of a nondisplaced fracture. There is a full-thickness articular cartilage cleft along the median eminence of the patella with underlying subchondral signal abnormality. There is partial-thickness articular cartilage degeneration along the medial facet of the patella. Increased signal abnormality within the medial femoral condyle and medial tibial plateau may reflect resolving bone contusions.LIGAMENTS: There is increased signal abnormality within the proximal fibers of the superficial band of the MCL indicating partial tearing (image 14; series 7). The LCL appears intact. The ACL and PCL appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
