Figure 3 OKS T-scores feedback model stratified to patient demographics. Figure showing the longitudinal course of expected patient outcomes. The exemplary course (green line) of an individual patient undergoing total knee arthroplasty at 3 different points prior to and following surgery is presented in terms of t-scores against a background of an age and gender matched population. The dark grey area is the range for +/- 1 standard deviation of the appropriate matched population and the light grey area the range for +/- 2 standard deviation.
