Long-term clinical success of KJD 53 3 Structural outcome In patients who survived for at least 9 years, the minimum JSWwas still statistically significantly increased at 7 years when compared to baseline (1.3 mm (IQR 2.5) and 0.3 (1.9), respectively; p= 0.017; Figure 3A). The mean JSW of the MAC in these patients was 3.0 (SD 2.3) mm at 7 years and 2.6 (1.6) mm at baseline ( p= 0.505; Figure 3B). The bone density at 7 years was 40.4 (SD 3.5) mm Al eq compared to 43.6 (6.5) mm Al eq at baseline ( p= 0.173; Figure 3C). In patients who received TKA in the years after KJD, no statistically significant differences in structural parameters were found between the last measurement and baseline. The minimum JSW was 0.4 (IQR 1.8) mm at last measurement compared to 0.2 (1.5) mm at baseline ( p= 0.161; Figure 3A dotted line). The mean JSW of the MAC was 2.5 (SD 1.8) mm at last measurement and 2.7 (1.2) mm at baseline ( p= 0.712; Figure 3B). The same was found for the bone density in patients who failed treatment, which was 41.3 (SD 4.9) mm Al eq at last measurement and 40.4 (2.9) mm Al eq at baseline ( p= 0.447; Figure 3C). Figure 3 : (A) Minimum joint space width (JSW) of the most affected compartment (MAC) of survivors 9 years after treatment versus patients whose treatment failed within 9 years. (B) Mean JSW of the MAC of survivors 9 years after treatment versus patients whose treatment failed within 9 years. (C) Mean bone density of the MAC of survivors 9 years after treatment versus patients whose treatment failed within 9 years, shown relative to baseline as survivors have a higher baseline bone density. Mean values and standard errors are shown.
