The Subchondroplasty® Procedure is a minimally-invasive, fluoroscopically-assisted procedure that targets and fills subchondral bone defects, sometimes called Bone Marrow Lesions (BML). It is usually performed along with arthroscopy, for visualization and treatment of findings inside the joint.

The procedure consists of four main components:

1. Preoperative plan: identify the patient's BML on fat-suppressed MRI, using at least two planes; plan approach and trajectory, based on BML location.

2. Target the BML: using intraoperative fluoroscopy and targeting assistance with an SCP® Navigation Guide, localize the bone defect relative to MRI findings.

procedure: navigate

3. Access the bone defect: insert the appropriate AccuPort® Cannula to the bone defect, using an orthopaedic wire driver.

procedure: access

4. Fill the bone defect: inject the desired volume of AccuFill® Bone Substitute Material (BSM) into the bony defect.

procedure: fill

Important Information: The use of AccuFill® BSM is not intended to be intrinsic to the stability of the bony structure. Radiographic studies should be used to confirm that the adjacent cortical bone is intact.
