Fig. 4. The regression lines of the medial meniscus extrusion (MME) increase rate in relation to the age, body mass index (BMI), femorotibial angle (FTA), and medial joint space width (MJSW). Scatter plots of the correlation between the MME increase rate and age (R2=0.019; A), BMI (R2=0.001; B), FTA (R2=0.031; C), and MJSW (R2=0.432; D).
