Figure 1

AViKA treatment arms. This figure depicts the two treatment arms of the AViKA study: the care navigator arm and the usual care arm. Patients in both arms received questionnaires at baseline and post-operative months three and six. Patients in the care navigator arm also receive regular phone calls from the care navigator. The time points designated in parenthesis indicate the post-operative time point (that is, “Call from care navigator (week 4)” indicates that the care navigator called the patient one month after the date of the patient’s TKA).
