title: MRI findings of subchondroplasty of the knee: a two-case report.
abstract: Bone marrow lesions observed in magnetic resonance imaging (MRI) have been recognized as a source of knee pain. Subchondroplasty was developed to treat these lesions with a percutaneous injection of calcium phosphate bone substitute into the bone. As subchondroplasty may potentially become a more common procedure in the treatment of knee osteoarthritis, it is important for radiologists to recognize the typical MRI findings and not to confuse them with other pathology. Here we report the MRI findings for two patients following subchondroplasty.
