52 Chapter 3 Survivors reported improvement in pain, stiffness, and function 9 years after treatment compared to baseline (32 points (95%CI 20.1–45.1; p< 0.001), 22.4 points (3.6–41.2; p= 0.026), and 31.0 points (17.1–44.8; p= 0.001), respectively). In patients who obtained TKA in the years after KJD, increases for pain, stiffness, and function were observed at last reported scores compared to baseline, 16.7 points (-7.0 to 40.3; p= 0.143), 18.7 points (-2.7 to 40.2; p= 0.079), and 21.0 points (-2.3 to 44.3; p= 0.072), respectively. Both survivors and those that underwent TKA reported a statistically significant average improvement in VAS pain scores compared to baseline (-46.8mm (95%CI -31.6 to -61.9; p< 0.001 and -25.4mm (-3.2 to -47.7; p= 0.030; Figure 2B). Last-reported VAS pain scores were better in survivors (25.0 (10.9–39.1) and 48.9 (28.4–69.4); p= 0.046).
