Variables	Scores^a	Group 1 (n = 22)^b	Group 2 (n = 22)^b	p-value
1. Degree of defect repair and filling of the defect	20	14.89 ± 3.39	14.32 ± 4.40	0.63
2. Integration of the border zone	15	10.85 ± 3.69	9.83 ± 3.67	0.36
3. Surface of the repair tissue	10	7.73 ± 2.55	5.68 ± 2.31	0.008
4. Structure of the repair tissue	5	3.24 ± 1.99	2.27 ± 2.17	0.13
5. Signal intensity of the repair tissue	30	14.32 ± 8.83	8.01 ± 4.43	0.005
6. Subchondral lamina	5	2.95 ± 1.83	1.93 ± 2.17	0.10
7. Subchondral bone	5	2.16 ± 2.22	2.61 ± 2.14	0.49
8. Adhesion	5	4.55 ± 1.19	4.77 ± 0.63	0.43

Total Scores	100	64.49 ± 18.27	53.01 ± 12.14	0.018

^aThe highest scores possible for each variable. ^bValues are given as the mean ± standard deviation. MOCART = magnetic resonance observation of cartilage repair tissue, Group 1 = experimental group (microfracture + atelocollagen augmentation), Group 2 = control group (microfracture alone)
