Subchondroplasty: What the Radiologist Needs to Know.
OBJECTIVE
Subchondroplasty is a novel minimally invasive procedure that is used to treat painful bone marrow lesions in patients with knee osteoarthritis or insufficiency fractures. The objective of this article is to describe the surgical technique and the pre- and postoperative imaging findings of a small case series acquired at a single center.


CONCLUSIONS
The radiologist should be familiar with the anticipated postoperative imaging appearances after subchondroplasty and the potential complications.
