Right knee pain MENISCI: There are no meniscal defects.ARTICULAR CARTILAGE AND BONE: There are no fluid-filled cartilaginous defects.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: There has been prior MPFL reconstruction. The graft appears thick but intact, with metal artifact in the distal femoral diaphysis due to the fixation screw. There is mild thickening and irregularity of the lateral retinacular structures, likely representing surgical changes and scarring from prior release.ADDITIONAL
1. Surgical changes related to prior MPFL reconstruction and presumed lateral retinacular release, as described above.2. Borderline tibial tubercle-trochlear groove distance and mildly elevated Insall-Salvati ratio; subjectively, the femoral trochlea appears slightly shallow.
