Magnetic resonance imaging analysis four years after transplantation of the graft in focal degenerative cartilage defects

Characteristic	Magnetic resonance imaging score
	1 (normal)	2 (mild)	3 (moderate)	4 (abnormal)
Defect filling	11 (complete filling), including 3 with minimal hypertrophic changes (<125%)	5 (>50%)	1 (<50%)	0 (no filling)
Signal intensity	8 (normal)	8 (some hyperintense areas)	1 (hyperintense areas)	0 (no signal)
Subchondral edema	4 (no edema)	7 (mild edema)	5 (moderate edema)	1 (distinct edema)
Effusion	1 (no effusion)	11 (mild effusion)	4 (moderate effusion)	1 (distinct effusion)
