From: Ten-year survival rate after rotational acetabular osteotomy in adulthood hip dysplasia

Fig. 3

Kaplan-Meier survival analysis of rotational acetabular osteotomy for total hip arthroplasty (THA) requirement and osteoarthritis (OA) progression in the patients with postoperative center edge (CE) angle ≤ 40° (non-overcorrection group) and > 40° (overcorrection group). There was no significant difference in the THA-free survival rate between the 2 groups (a) and in the OA progression survival rate (b) during the 10-year follow-up (numbers at risk = 65 hips in the non-overcorrection and overcorrection groups)
