Figure 2.

A) Representative T2 maps of the IPFP in four individuals with TKA (76 yr. old female with no scarring, 57 yr. old female with mild scarring, 57 yr. old female with moderate scarring, and 62 yr. old male with severe scarring), displaying shortening of T2 with increasing levels of IPFP scarring. B) Box plot of mean T2 values of IPFP full volume regions vs. IPFP fat pad scarring. T2 values of abnormal regions were shorter in individuals with severe scarring compared to those with moderate, mild, and no scarring. For each box, the central mark indicates the median, and the bottom and top edges of the box indicate the 25th and 75th percentiles, respectively. The whiskers extend to the most extreme data points not considered outliers, and the outliers are plotted individually using the red ‘+’ marker symbol
