Percentage change in femoral cartilage cross-sectional area due to the braced and nonbraced conditions in all participants. The percentage change in ultrasonic femoral cartilage cross-sectional area due to a standardized 3000-step walking protocol both with (braced) and without (nonbraced) a knee brace designed to offload articular tissues for all individuals (n = 33). The horizontal line indicates the median. The upper and lower hinges correspond to the first (25th) and third (75th) quartiles, respectively. The interquartile range is the distance between the first and third quartiles. The whiskers indicate the smallest and largest data points within 1.5 × interquartile range of the respective hinge.
