Fig. 5A–C.

Kaplan-Meier survivorship curves of eccentric acetabular osteotomy with the end point defined as conversion to THA are shown for older patients (Group O) and younger patients (Group Y). The 95% CIs are shown on only one side of each curve. Survivorship is shown for (A) all patients, (B) patients with unilateral surgery only, and (C) patients with bilateral surgery only. Survivorship was similar (p = 0.644) in both groups regardless of age and whether the osteotomy was unilateral or bilateral.
