Kaplan-Meier survivorship curve with conversion to total hip arthroplasty as the end point. We set up the time point from 0 month to 80 months postoperatively on the -axis. The -axis shows the survival rate. The dotted line shows the survival rate for all of the hips. The survival rate of the entire group was 83.87%. The result shows that the applied protocol can be used for end-stage ONFH.
