39-year-old male with left knee pain MENISCI: Small cysts are noted anterior to the anterior horn of the lateral meniscus, but we see no underlying meniscal tear. The medial meniscus appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is superficial degeneration of the articular cartilage of the lateral facet of the patella. There is also a linear focus of low signal intensity traversing the articular cartilage of the femoral trochlea centrally that may represent a cartilaginous fissure. The articular cartilage of the tibiofemoral compartment appears intact.LIGAMENTS: The ACL appears intact, but there are small linear foci of increased signal intensity between its bundles that may reflect mild mucoid degeneration. There is thickening of the proximal fibers of the MCL with ossification within its proximal fibers at its femoral attachment indicating prior injury, but we see no findings to indicate an acute tear. The PCL appears intact. The LCL appears intact.EXTENSOR MECHANISM: Subjectively, the quadriceps tendon appears slightly thickened with enthesophyte formation at its insertion on the patella, but we see no tear. The patellar tendon appears intact.ADDITIONAL
1. Patellofemoral cartilage degeneration with a borderline tibial tubercle trochlear groove distance.2. Other findings as described above.
