Table 3 Consensus meeting modifications
Domain | Modification |
|---|---|
Volume filling of cartilage defect | Now includes 3 categories representing “complete cartilage volume filling”, “any overfilling or underfilling”, and “complete void” |
Cartilage Integration | Integration described as “complete”, “incomplete”, or “no integration” |
Surface of Repair tissue | Surface described as “intact”, “not intact”, or “no repair tissue present” |
Structure of the Repair Tissue | Structure defined as “homogeneous”. “heterogeneous”, or “no repair tissue present” |
Bony Changes | Modified to focus on bony overgrowth as opposed to defects. New criteria included “no intralesional osseous overgrowth”, “some intralesional osseous overgrowth”, or “complete intralesional osseous overgrowth” with more bony overgrowth representing a worse score |
Subchondral Changes | Criteria for “edema-like marrow signal” were removed and simplified into “no intralesional subchondral changes”, “presence of intralesional edema”, or “present of intralesional subchondral cyst” |
Cartilage Delamination | Although initially part of the volume filling of cartilage defect domain, given the different mechanism from volume filling delamination given its own domain evaluating the presence or absence of delamination at the chondrolabral junction |
Signal Intensity of Repair Tissue | Domain removed entirely given difficulty in assessment with poor-quality MRI |
