Early Complications of using Dual Mobility Cup in Total Hip Arthroplasty. A Systematic Review

Abstract

ual mobility THAs are a good alternative to traditional bearing surfaces with long survivorship and low rates of instability after primary and revision THA. Reducing or preventing medical and mechanical complications such as instability will be of paramount importance particularly in an emerging health care environment based on patient quality of life and functional outcomes. The incidence of complications of primary dual mobility THAs is lower than that in revision dual mobility THAs with the exception of intra-prosthetic dislocation. The rate of complications which are unique to the procedure, including intra-prosthetic dislocation, is relatively low and limited mainly to earlier designs. High-quality, prospective, comparative studies are needed to further evaluate the use of dual mobility in primary and revision THA.
