Incidence of total hip arthroplasty in patients with Legg-Calve-Perthes disease after conservative or surgical treatment: a meta-analysis.

Patients with LCPD had relatively low incidences of THA. The greater the age at disease onset and longer the follow-up, the higher the incidence of THA; however, the Stulberg classification was not directly associated with the incidence of THA.
