medial compartment:
- interval subchondroplasty - stellate hypointense signal centrally within the medial femoral condyle corresponding to bone cement on x-ray
- mild interval collapse along previously-identified insufficiency fracture (best visualized on coronal T2FS)
- new partial thickness defects of central cartilage overlying the lesion, which may represent changes of chrondroplasty or chondrosis
-

- interval removal of loose body at posterior intercondylar notch
- mild improvement in small knee joint effusion and superficial edema/bursitis
